Replacing Kalina brake discs with your own hands: repair features

Brake discs are an important component of the braking system. The amount of time it takes to stop the car depends on the type of disc, quality and material of manufacture, and degree of wear. Often, due to wear, the wheel moves to the side, the working cylinder and pads jam.

Systematic technical inspection of the car, its elements, and assemblies will prevent negative consequences and premature breakdowns.

The process of replacing discs yourself is not at all difficult; every car owner can do the job. If you don’t have time, contact the service center to provide qualified assistance.

What front brake discs can be installed on Lada Kalina 2

By default, non-ventilated discs with grooves from a domestic manufacturer are installed on cars of the Lada family. The workmanship is not bad, but it is not enough for a long time.

We felt vibrations and beating in the steering wheel - the first sign of uneven wear. Carry out preventative maintenance as soon as possible, followed by replacing worn out elements.

The standard disc size is 19.0 mm. The maximum permissible minimum thickness of use is 17.8 mm, after which it is unsafe to use the brake system element. Similar standards apply to Lada Largus, Granta, Priora, Niva.

Advantages and disadvantages of different types of brakes

People tend to quickly get used to the conveniences that various technical means provide them. Do you have a desire to find out what is good about the rear disc brakes installed on Kalina?

Many experienced drivers will argue that rear disc brakes are much more effective than drum brakes. And we can quite agree with them. Naturally, skeptics will find shortcomings in such a braking system.

It's no secret that rear disc brakes are much more expensive than drum brakes. Caring for a disk system is much more difficult because it really does not like dirt. Particular difficulties arise if the car is an SUV. In general, there are many opinions from both experienced and novice drivers about which brakes are best.

Kalina Sport brakes are very effective

Not long ago, a comparison was made of the performance of rear disc and drum brakes. The difference of two meters in braking distance speaks for itself. The only condition for this check was that the brake system must have a certificate of conformity, which would guarantee the car’s ability to easily pass state technical inspection.

As a result, it was proposed to test two similar configurations, but different ones were provided by the first Ford Focus model, and the AvtoSportTekhnika organization provided the Chinese Cherry. As a result of the tests, the opinions and assumptions of skeptics were successfully debunked.

Reinforced hoses - advantages

Reinforced hoses were developed to complete sports and track versions of cars. The average pressure for which the tube is designed exceeds 300 bar. This means that the car can experience emergency braking several times a minute at a speed of at least 150-170 km. at one o'clock. The high-speed distance is not much less than that of a car with rubber hoses, and the price of the product is quite high.

Each driver will decide for himself whether to replace the standard hoses in his car with reinforced ones.

The fact that the brake pedal becomes more “obedient” is true, but only when the driver rushes along city roads at a speed of at least 150 km. per hour, while making turns on turns, and spits on all the rules, other drivers, pedestrians and inspectors, feeling like a local Schumacher.

Among the advantages of a reinforced hose are the following:

1. Under pressure, a rubber hose is subject to greater tension than a line protected by a steel braid. The service life of a reinforced part is three times longer.
2. Braking time is reduced by 50% due to the instant transfer of kinetic energy to the pad-disc pair after pressing the brake pedal.
3. Reinforced hoses do not allow air to pass through, which prevents water droplets from accumulating in the brake fluid.

• type of thread on the fitting;
• fitting size;
• hose angle;
• The fixing mount when turning the wheel does not correspond to the factory one.

How to do the replacement yourself

Before starting repair work, we carry out comprehensive diagnostics in order to study the general technical condition of the car, identify the breakdown, calculate time, effort, and resources. Often the cause is a faulty working cylinder, system depressurization, or pipe damage.

We carry out diagnostics by placing the car on the inspection channel, jacking up each wheel one by one, and measuring the thickness of the disk. If the actual value is less than 17.8 mm. - replace it with a new one, subsequent operation is unsafe. Otherwise, we continue the inspection and troubleshoot the brake pads and working cylinder.

Preparing to replace the AP

Having determined that the TD is faulty, you need to prepare to change them yourself. To do this, you first need to buy a new spare part from a car store.

When choosing brake discs for his car, the car owner must take into account his driving style. Does he like to accelerate sharply and actively maneuver? How often does he use the brakes? He drives a lot around the city or mostly intercity trips on the highway.

The spare part from which manufacturer you need to buy depends on these factors. Discs can be standard or sports.

• Standard TD - made of cast iron, the casting is processed on a milling machine. They are ventilated and non-ventilated. Without ventilation, it is a single disc that is pressed on both sides by brake pads. A disk with ventilation is easy to distinguish - it is two disks connected by bulkheads. Ventilation occurs during movement due to air entering between these pancakes. Some of the respected manufacturers of these products are Bosh, Zimmerman, ATE.
• Sports TD - made of durable and ultra-strong gray cast iron, as well as austenitic stainless steel. These are considered to be more durable products that can last much longer and with more aggressive driving. Such discs are produced by EBC, DBA, Brembo.

The driver must remember that when the front brake discs are replaced, they must be changed in pairs, even if one of them is suitable for further use in all respects. The same rule applies to rear brakes.

This rule is explained by the fact that unequal weight of the same type of spare part on the wheels of the same axle will lead to loss of directional stability.

Sequencing

• We install the machine on a flat surface; for convenience, you can use a hydraulic lifting mechanism;
• Remove the wheel, unscrew the upper and lower guide on the caliper. We move it to the side and do not unscrew the brake fluid supply line. To make work easier, simply hang the caliper from the front strut (spring) housing;
• To dismantle the disk, unscrew the two bolts on the hub and hold the disk from turning;
• If necessary, tap the disc around the perimeter with a hammer from the end part. Direct impacts are prohibited, as there is a high probability of chamfer deformation;
• After removing the disk from the splines, we carry out troubleshooting, clean it of debris, and apply a thin layer of graphite lubricant to the guides;
• We install a new disk and assemble the structure in the reverse order.

When finished, press the brake pedal 3–4 times, bleed the system, and check the DOT level -4. We fill the missing amount as needed in the expansion tank of the master cylinder.

This completes replacing the brake disc with your own hands. Next, we carry out the procedure similar to the second wheel.

Changing the rear pads

Replacing the rear brake pads of a Lada Kalina is a complex operation, and it’s good that it is recommended to perform it every 60,000 km (4th scheduled maintenance). The principle of operation of drum brakes is easy to explain: there is a cylinder installed under the drum and two pistons that press on the pads. But in practice, disassembling the drum mechanism turns out to be more difficult than changing disc brake pads.

Steps to replace drum brake pads, VAZ-2192/2194

First of all, you will need to fix the car body on the support stand, and only then can you remove the rear wheel. Next, the sequence of actions looks like this:

1. The handbrake handle is lowered all the way down;
2. 7 wrench (socket wrench with a hex head), unscrew the two studs holding the drum;
3. The brake drum must be removed: the body is turned by lightly hitting it with a hammer through a block in the “toward” direction;
4. Remove the upper and lower tension springs, remove the pad stops from the piston slots;
5. Short guide springs are disconnected from each of the pads (there will be two in total);
6. The block located closer to the front side of the body is removed. Then, remove the spacer bar;
7. The second block is removed along with the parking brake lever.

Finally, the block and the handbrake lever will need to be disconnected (just remove the mounting cotter pin). Installation is carried out in reverse order. To quickly secure the guide spring, insert a wire into its eyelet and pull it towards you.

Installation of brake pads in drums, VAZ-2192/2194

The photos posted in this chapter show parts with serial number 3502090-01 (“Standard”). More expensive trim levels use pads 3502090-10, which have a slot for the ABS sensor.

Check out what we said in the previous chapter. New pads must first be allowed to “break in”. Their effectiveness can be assessed after several hours of continuous use.

When considering how to replace the cabin filter, we listed the manufacturers of parts and the differences in designations. In this case, the parts are designated the same: 3502090-01 or 10 (rear pads). As for the front pads, there will be several options:

• 1118-3501080-00 – manufacturer is AvtoVAZ;
• 1118-3501080-05 – issued by JSC TIIR;
• 1118-3501080-15 – the same as “05”, but with an anti-squeak plate;
• 2192-3501080-19 – the same as “05”, but with an anti-noise complex.

Don't go wrong with your choice! As a last resort, you can contact specialists, but preferably not the ones shown here.

Algorithm for replacing rear discs on a second generation Lada Kalina

The process is similar to installing the front ones, except for the shape and method of fixation.

• We jack up the rear wheel, block the front part with wheel chocks;
• Unscrew the bolts, remove the wheel, unscrew the two mounting bolts, and remove the drum. If dismantling is difficult, carefully tap along the perimeter so as not to damage the edge;
• We carry out troubleshooting of brake pads, pressure springs, spacer bars, and handbrake cables. Replace with new ones as needed;
• We put on a new drum disc, screw in two bolts, and complete the installation.

When finished, bleed the system by repeatedly pressing the brake pedal. We replenish the missing amount of brake fluid in the reservoir.

Subject to compliance with installation technology, purchase of original consumables, moderate driving style, subsequent maintenance after 35,000 km. Which brake discs are better - obviously with factory catalog numbers and in the original design.

Features of Kalina Sport

Lada Kalina Sport was created in 2008. After the release of the first car, the state registration of the model was successfully completed. Soon Kalina Sport cars were sent to Yaroslavl, Moscow, Izhevsk, Vologda, Voronezh, Perm, Volgograd, Kirov, Orenburg, Krasnoyarsk and other cities of the country.

Lada Kalina Sport is very similar to the Lux model. The sports version of Kalina differs in that it contains quite a lot of different original parts. These are door moldings, an exhaust pipe nozzle, a combination of various instruments with white scales and orange backlighting, original bumpers, a spoiler, and a nameplate on the fifth door. The interior of Kalina Sport is made in an elegant dark color, which gives it a special chic and uniqueness. The car is equipped with special sports pedal pads.

If we talk about brake discs on Kalina Sport, then most car enthusiasts claim that they are better on a regular Kalina. Of course, opinions differ, so which brakes to choose when purchasing a car is up to the buyer himself to decide. Good luck in choosing a car!
