Why is the brake light on?

But let's start with the design features of the brake system alarm. Previously, cars used only one sensor - the level of brake fluid in the system, which sent a signal to the warning lamp. Since fluid is the main working element of the system, and its leakage leads to the brakes stopping working, naturally, the designers installed a sensor to monitor the level.

Additionally, the car also has a parking brake, the use of which must be monitored by the driver. On some models, the warning lamps for the working and parking systems are separated. The warning light with an exclamation mark in a circle is responsible for the fluid level, and the indicator marked with the letter “P” signals that the handbrake is engaged, and it turns off after the car is released from the handbrake.

But often a car has only one warning light, to which both the liquid level sensor and the handbrake sensor are “attached”.

Modern cars use circuits that additionally include brake pad wear sensors and brake light lamps. Failure of these elements causes the lamp on the dashboard to light up.

There are other design nuances that cause the indicator to glow. On VAZ models of the 10th family of the first years of production, a starter protection relay was included in the circuit, which forcibly turned it off after starting the engine. In this circuit, the designers connected the power supply circuit for the brake system lamp to this relay.

Why does the brake warning light on the dashboard come on or does not go out after starting the engine? If this happens while moving, it is better to stop moving and carry out diagnostics. If the light does not go out after starting the engine, it is better not to drive until the problem is resolved.

Checking the serviceability of the handbrake

Every car enthusiast can carry out the simplest diagnosis of proper operation of the parking brake. Select a section of road with a slope of 23–25%. Stop, put the gear in neutral and tighten the handbrake. If the car does not move after releasing the main brake pedal, then the handbrake operates.

How to use the handbrake

On a note. Car maintenance service workers recommend checking the operation of the parking brake at least once a month.

When tightening the parking brake lever, pay attention to the number of clicks of the ratchet mechanism. If the handbrake is in good condition, there should be from two to four clicks. If there are fewer of them, then you need to release the parking brake drive. Otherwise we tighten it up. Let's look at step-by-step adjustment of the handbrake using the example of a Lada Kalina car.

Possible reasons why the handbrake light is on: opinions of car owners

1. Changed the hubs. “The light in my car blinked sometimes. At first I decided that the problem was with the pads. But later I remembered - I replaced the pads not so long ago. I checked the brake, everything is fine. And then I thought about why the problem could arise? I didn’t think of anything and stopped worrying. The indicator continued to flash periodically... As a result, the right hub bearing began to make noise, after a while it began to hum so loudly that the sound simply made my head split. I first purchased one hub. Then I thought that it would be better to change both parts at once - or rather, this should be done. I bought a second one, changed it, and the problems all disappeared: no noise, no blinking light.”
2. Got a good technician! “The handbrake light would come on from time to time while driving. Quite often this happened after bouncing on the pit. I went and bought a brake fluid. And I found a specialist right at the dealership. He then flooded it. He also climbed under the handbrake and said that perhaps the microphone at the lever was acting up (it seems like this happens sometimes). Take the train and watch. But the problem disappeared after filling the brake fluid. The handbrake no longer lights up. By the way, I met an excellent specialist and looked for the problem for free, with pleasure and without showing off.”

3. Depending on the situation, “If the light starts to light up after shocks, for example, on a hole or bump, then, most likely, the brake fluid level is on the verge of the required level or lower. You just need to add it and that's it. If it lights up when braking, the pads are definitely worn out completely. I went through this myself in my VAZ.

Options for self-diagnosis of the system if ABS lights up on the instrument panel

The on-board computer reports the presence of errors in the functioning of a particular unit. The display will show a code corresponding to the specific problem.

Important! The set of error codes and their designations vary. It all depends on the manufacturer

It is necessary to clarify the decryption in the user manual or on the Internet.

Diagnostics can be done on your own. You can do something from the list below.

Self-control test. On a dry section of a normal road we accelerate to 100 km/h. Turn off the radio, close all the windows, listen carefully. Did you hear a cracking sound (from the front, rear, right or left side)? There may be play in the hub bearing. Visiting a car wash

During the cleaning process, instruct that special attention be paid to the discs and hubs. Thorough cleaning will eliminate the spontaneous ignition of the ABS check. Checking fuses

If the one responsible for the anti-lock braking system has burned out, replace it. We put the car on a jack, carefully examine the sensor area, and check the integrity of the cables. Noticed corrosion or dirt? We clean it carefully. After this, the ABS activation should disappear.

The most reliable way (and the most expensive) is to send the car for diagnostics to a service center. Thanks to special equipment, specialists can find faults quickly and accurately. Alternatively, you can take care of purchasing such equipment, but its price may be completely unaffordable for some.

How is the replacement performed?

When replacing Renault Logan parking brake cables, our video will show you what to do when doing the repair yourself. It is worth noting that the right and left rear cables are changed in the same way.

To restore the handbrake of Renault Sandero, LADA Largus, the installed cable is removed and replaced as follows:

1. The tension of the drive cables is loosened by unscrewing the adjusting drive nut on the handbrake.
2. The brake drum is removed.
3. The rear brake pad is removed, and the cable tip is disconnected from the lever, which removes the pad itself.
4. The cable sheath clamp is compressed.
5. The cable is removed from the hole.
6. The cable is removed from the holder located on the beam lever.
7. It is necessary to pull it a little into the cabin, and then remove it from the equalizer.
8. We completely remove it from the hole in the body.

When replacing the handbrake cable on a Logan, you may encounter a situation where it cannot move freely in the sheath. Therefore, it must be lubricated with transmission or engine oil (at your own discretion).

Even before replacing the handbrake cable, it is important to make sure that the new cable is long enough to be installed on the vehicle. Otherwise you will have to buy a new consumable.

As is clear from the instructions, the procedure is quite simple. The parking brake will be repaired only if all operations for independently replacing the cable and checking its operation by placing the car on an incline on the handbrake are followed. The new part is guaranteed to last for several years without any problems.

Parking brake device

Before replacing the handbrake cable or tightening it, you need to understand the design of the mechanism. It is designed quite simply and consists of the following main parts:

1. Lever with spring-loaded button and latch. Located in the cabin on the right hand of the driver.
2. A metal rod with a pin at the end and a rocker arm for installing the cable is located under the bottom of the car and attached to the lever. This is the “handbrake” tensioning device.
3. The ends of the cable (or two cables), installed on the rocker arm, are attached to the brake levers of the rear wheels - disc or drum.

The parking brake works like this: when the driver lifts the lever in the passenger compartment, the rocker moves forward and acts on the pads through a cable drive. In drum mechanisms, the brake pads move apart, and in disc mechanisms, they converge. The “handbrake” holds only the rear wheels and functions independently of the main brake system, which is activated when the pedal is pressed.

When to tighten and when to change?

During operation of the machine, the steel cable gradually stretches and begins to sag. Then part of the lever stroke is used to remove this slack (the first 2-3 clicks), and only then the force is transferred to the brake pads of the rear wheels. As a result, they are weakly pressed against the surface of the discs or drums and the car does not brake reliably.

The first sign of a malfunction is that the handbrake stops working on the first two clicks of the handle and is raised by hand without any effort. In this case, it is definitely necessary to tighten the hand brake, or rather the cable drive.

But the operation of the mechanism also depends on other factors:

• on the degree of wear of the brake pads;
• from the depth of excavation on the surface of the steel disk or drum.

Abrasion of the linings does not have much effect on the operation of the main system, since the stroke of the hydraulic pistons is quite large. But the effect of the mechanical “handbrake” gradually weakens. To return it to working condition, it is necessary to compensate for the wear of the elements by tensioning the drive.

The cable is replaced in the following situations:

1. The element has stretched to such an extent that at maximum tension the pads do not grip the discs and the car rolls away on any slope.
2. Due to the constant ingress of water under the cable casing, it rusted and became tightly jammed. This happens when a motorist rarely uses the handbrake.

Cable jamming also occurs in winter, when water trapped under the casing freezes inside. In this situation, do not rush to change it; first warm up the car in the garage, and then drive out the moisture using WD-40 aerosol lubricant.

Instructions for tensioning and replacing the drive

Since the parking brake system mechanism is located under the bottom of the car, an inspection ditch, overpass or lift is needed to perform the work. In extreme cases, you can do without them, but then you will have to hang out the back of the car and lie under it, which is not only inconvenient, but also dangerous. Before tightening the cable, securely secure the front wheels of the vehicle with wheel chocks.

Then act in the following sequence:

1. Set the handbrake lever to the down position.
2. Jack up any of the rear wheels.
3. Armed with two open-end wrenches that fit the tensioner nuts, go down into the inspection hole.
4. While holding the main nut located on the stud near the rocker arm, loosen the locknut.
5. Tighten the tension nut, periodically checking the rotation of the suspended wheel by hand. To prevent the pin from spinning, it must also be held with pliers or a wrench.
6. Stop tightening the cable as soon as the pads begin to grip the wheel. Make 1-2 turns of the nut back and check the operation of the handbrake. It should fire after the second click.
7. Tighten the locknut, lower the jack and test the handbrake on a slope.

When to tighten the nut

If this does not help you, you will have to use the adjusting nut to adjust the brakes. To do this you need to do the following.

1. Open the plastic plug under the handle. It can be easily removed.

2. Remove another plug, under which there is an adjusting nut.

3. Take a long 10mm socket and tighten the nut.

This completes the adjustment of the hand brake on the Lada Vesta. But I didn’t do this on my car (or rather, not mine, but my wife’s), because I think that automatic adjustment was enough. Therefore, I also advise you to use the automatic function first. If this is not enough, then tighten the nut.

On the Lada Vesta, to adjust the handbrake you no longer need to crawl under the car, as before on the “nines” and “fours”. I hope that the review was useful for someone, and someone probably already knew this trick. Thank you for reading, good luck on the roads everyone!

Adjusting the hand brake on Lada Largus

The first step is to unscrew the bolt securing the plastic casing under the handbrake lever, which is clearly shown in the photo below:

Then remove this cover completely so that it does not interfere.

Then, under the lever itself, we bend the so-called cover to the side, and there we see a nut on the rod. You need to tighten it clockwise if you want to tighten the handbrake. After several revolutions, it is advisable to check the operation of the handbrake so that it is not overtightened.

It is most convenient to tighten using not a regular open-end wrench, but a socket wrench or a deep socket with a crank.

When the adjustment is completed, you can put all the removed interior parts back in place.

Typically, adjustment is required very rarely and it is possible that during the first 50,000 km you will never even do this once, since it will not be necessary.

Components

In such a situation, there are 2 scenarios:

1. Carry out modifications in accordance with the factory diagram;
2. Purchase components from another manufacturer.

And so, one of the owners of the Lada Vesta in the Exclusive configuration said that he was able to find out from an AvtoVAZ employee exactly what components were needed to replace drum brakes with disc brakes.

According to an employee of the plant, there is no need to replace the beam or reflash the ABS block, and this significantly speeds up and reduces the cost of the work.

In addition, the picture clearly shows that there is a standard spacer between the axle and the beam and it is to this spacer that the boot is fixed. From the factory, the hub and disc come separately, so after installing the rear disc brakes on the Lada Vesta yourself, there is no need to replace the bearings if you need to replace the disc.

All the components necessary to replace the brakes with your own hands are presented in the table along with the article numbers.

The estimated cost of the entire kit for self-installation of rear disc brakes on a Lada Vesta is about 30,000 rubles.

The principle of adjusting the handbrake

1. Fully lower the handbrake lever in the cabin.

Lower the handbrake handle

• Place the car on a pit or lift it on a lift. Some car owners manage to adjust the handbrake “from the curb” - but this is inconvenient and dangerous.
• Find the resonator from the bottom of the car and remove it from the rubber brackets.
  Remove the muffler from its mounting to the body

  Using a ratchet, unscrew the 4 bolts securing the protection of the handbrake adjustment mechanism (protective screen).

  Remove and set aside the protective screen

  Next, you can either remove the protective screen, but it seems to me that it is easier to move it forward behind the muffler, which will free up space that is enough for free work.

  The mechanism looks like this

  Loosen the first nut with a 13mm wrench.

• By tightening the adjusting nut, tighten the handbrake cable that comes out of the passenger compartment.
• Ask a partner to check the stroke of the lever handle, or check it yourself.
• As soon as the handbrake moves 3-4 clicks, tighten the lock nut.
• Before the final stage of work, it is necessary to check the functionality of the brake mechanism. To do this, hang the rear wheels and watch how they rotate with the hand brake off. They also check how the wheels grip when the handbrake is raised.

The principle of operation of the handbrake on Grant

Why does it need to be tightened frequently?

This is the peculiarity of the mechanism, which is why you often have to tighten the handbrake. Plus low-quality spare parts from the beginning, and a design that has not changed since the time of Tsar Pea!

In foreign cars (not all of course), the rear brake mechanism (drum or disc) has self-tensioning springs, which are tightened depending on the wear of the pads.

How a properly configured handbrake should work

The handbrake movement in a Lada Granta car should be no more than 6 clicks from the moment it is raised. It is possible to increase the handbrake stroke to 8 clicks, but it is not recommended.

It shouldn’t be like this (the brakes don’t grab the rear wheels)

Ideally, of course, 3-4 clicks. With this setting of the handbrake, you will have a reserve of movement when the cable weakens and the wheels begin to grip later.

If you experience a situation where the handbrake is “pulled out” to its fullest extent, but the wheels do not grab, then the following reasons are possible:

1. rear brake pads are worn out;
2. the handbrake cable is broken or stretched/

Causes of malfunction and their elimination

As a rule, the reasons why the handbrake does not work are quite simple and do not require long or expensive repairs:

How to solve such a problem?

Some may sigh and say that they have finally reached the goal of this article. If so, then I would like to offer some tips for solving such problems:

• Check that all device contacts are securely connected. There are only five of them in the system, one near each wheel and the fifth is located in the engine compartment of the car. The check is easy to do; you need to disconnect all contacts, clean off any dirt and oxidation. When all this is done, they are installed in their place;
• If the reason for the warning light to turn on is the ABS control unit, it is almost impossible to solve this problem on your own. In cars with an on-board computer, you can see the error code for this system. If you know how to decipher these errors, you can learn about the problem more specifically, but this does not mean that you can solve it yourself.

If the ABS light on the instrument panel lights up, this indicates a malfunction in the vehicle's anti-lock brake system. In most cases, this icon lights up simultaneously with the icons of other related systems: ESP, ASR (exchange stability, traction control, etc.)

The ABS error indication shows the complete inoperability of the system, and not the error of its individual elements, as in the case of an error in the engine management system. The ABS system, as a rule, does not have emergency operating modes. A malfunction of one of the devices leads to a complete failure of the entire system.

This is especially dangerous when operating a vehicle on poor road surfaces. It is necessary to carry out computer diagnostics in order to find out why the ABS light comes on - to identify all possible causes of the malfunction, and take measures to eliminate them.

Checking the mechanical component

Self-diagnosis is a simple operation. It is divided into two components - mechanical and electrical. The first is very important, since it evaluates the condition of the brake system drive and determines its performance.

Checking the mechanical component is reduced to assessing the level of brake fluid in the reservoir and the condition of the drive lines and system components - the master brake cylinder and operating mechanisms.

The brake reservoir is located in the engine compartment, on the right near the rear panel of the engine compartment. It is not difficult to find it, since there are two wires going to the tank cap.

When checking, disconnect the wires and unscrew the cap to determine the brake fluid level. There are marks on the walls of the tank, by which you can understand how much liquid is left. A level above the middle between the marks is considered normal.

For an additional check, we start the car and press the brake pedal a couple of times, after which we roll the car back and inspect the surface of the ground for traces of leaking fluid, and check the fluid level. If it is detected, the brake line is damaged, and the amount of fluid will decrease.

If there is a brake fluid leak, the car cannot be used because the car does not have brakes. The best option in this case is to call a tow truck to deliver the car to the repair site. But if you have enough driving experience, then we get to the service station or garage on our own. Car brake systems usually have two circuits, and if the line of one of them is broken, the second continues to work.

Sometimes there is a problem with the warning light coming on when you press the brake pedal. The reason for this lies in two factors - low fluid level in the reservoir and worn disc brake pads. When braking, fluid flows into the working cylinders and the amount in the tank drops below a critical level, which is why the lamp lights up. This can be treated by installing new pads and adding fluid to the reservoir.

Recommendations for the braking system

• We recommend that you replace the brake fluid at least once every 1.5-2 years. During operation, brake fluid inevitably absorbs moisture, and its boiling point decreases. During intense braking, it can boil in the working cylinders, and an air plug appears in them, which will not allow creating the required pressure, and the efficiency of the braking system will sharply deteriorate. Check the brake fluid level periodically. If it begins to decrease quickly, it means there is a leak - contact service immediately. If the level decreases, but slowly (smoothly over a run of about 10-20 thousand kilometers) and reaches a minimum, check the condition of the brake pads.

It is advisable to change brake pads/discs if the wear percentage reaches 70% or more, because it is impossible to monitor their condition frequently, and besides, the inner pad wears out more. Maintaining the brake system in good condition is the key to the safety of you and your loved ones on the road.

Use only original and high-quality spare parts in the car’s brake system. Brake pads of questionable quality may not withstand the heat during emergency braking and will not stop the car. They may have a shorter service life, squeak when braking, or wear out the brake rotors quickly.
