Replacing brake fluid on a VAZ 2114 - which one to choose, when to change it

The VAZ 2114 car is equipped with a brake system with a hydraulic drive. A special feature of the vehicle on this machine is the diagonal distribution of the brake circuits. If one of them fails, the second provides braking with high efficiency. The working substance for vehicles is brake fluid VAZ 2114 “Rosa”, “Rosa-3”, “Rosa-DOT-4”.

WHEN TO CHANGE

The main reason for changing brake fluid is moisture getting into the system. This leads to unpleasant consequences. For example, it can simply freeze in winter (this cannot happen with a clean one), and this can cause not only brake failure, but also damage to pipes and other elements of the car. And replacing brake hoses on a VAZ2114 is not a pleasant matter. However, this process is quite long, and takes about 2-3 years, in the absence of breakdowns in the system, after which it is necessary to replace the brake fluid of the VAZ 2114.

In summer this problem is also relevant. Moisture, as you know, tends to boil. So, prolonged braking can lead to exactly this, as a result of which the car simply stops braking.

Mileage and intensity of brake use also affects fluid performance. For the VAZ 2114, it is recommended to change the fluid in the entire system after 30,000 kilometers. Detailed operating rules are listed in the vehicle documentation.

Bleeding brakes on a VAZ 2110

The brake system is a very important component of any car, regardless of its brand and other characteristics. Malfunctions of the brake system are one of the common troubles that arise every now and then during the operation of a car. However, in most cases they can be avoided if preventive measures are taken in time.

Why do you need to bleed the brakes?

Thus, one of the most common measures to prevent and ensure the stability of the brake system is bleeding the brakes. The essence of this event is to remove “excess” air and foreign liquids from the system. There may be several prerequisites for the appearance of “foreign” substances in the brake system:

• spare parts were replaced in the unit,
• violation of the integrity of the hoses,
• use of low-quality brake fluid, etc.

In addition, it should be understood that brake fluid has the property of being hygroscopic, that is, it has the ability to accumulate water. For this reason, sooner or later the liquid must be drained and the system, accordingly, must be pumped. Replacing brake discs with your own hands, by the way, also entails the need for bleeding, just like any other intervention in the brake system.

SIGNS OF PROBLEM

When the fluids are partially used up, the brake system begins to work incorrectly. The pedal begins to sink or becomes soft. Braking occurs silently, and the braking trail gradually increases. The car may skid when the brakes are pressed.

Having discovered one of the signs, the first thing you should do is look into the brake fluid reservoir. A cloudy color and the presence of sediment are an alarming signal; it’s time to go shopping, because you urgently need to change the brake fluid on your VAZ 2114.

How to carry out pumping yourself?

There are many ways to bleed the system yourself. The simplest, perhaps, is to use a fitting and a tube (or a tubeless spare tire). The bottom line is that the VAZ 2114 brakes are pumped using the pressure that is created in the expansion tank by connecting a chamber with air to it. To do this, you need to slightly alter the cover by screwing a fitting with a spool into it. But this method has a huge drawback - you will lose a large amount of liquid if you miss the moment. In addition, it is necessary to constantly monitor the fluid level.

REPLACEMENT PROCESS

Before starting work, you need to stock up on the following tools:

• Hose 10-15 centimeters long and 6 mm in diameter;
• Wrenches for 8 and 10;
• Plastic bottle;
• Gloves (work clothes and safety glasses are also a good idea);
• Hydraulic fluid (there are a lot of manufacturers, each with its own characteristics).

Having collected all the tools, you can start working. The procedure is not complicated and does not require any professional skills. Most motorists do the replacement themselves.

It is extremely difficult to do this kind of work alone, so I recommend taking a friend with you who will undoubtedly help in the process. This will not only save time, but will also greatly simplify the procedure.

We are changing bunker - 4 in the VAZ 2114 in stages:

1. We park the car on a pit or overpass;
2. Remove the cap from the brake reservoir;
3. We go into the pit. Here we need a fitting located on the rear right wheel;
4. It is closed with a cap, which we remove;
5. Take a bottle and pour some DOT-4 into it;
6. We put the hose on the fitting and lower the other end into the bottle (do not forget to lower it to the bottom);
7. Now you need someone to press the brake pedal. Smoothly 7-8 times in a row, and the last press all the way and hold;
8. Unscrew the fitting a couple of turns;
9. We observe how the waste product comes out;
10. When 1-1.5 centimeters remain in the tank (it is important not to be late, otherwise air will enter the system), tighten the fitting and release the pedal;
11. Add the missing DOT-4 to the tank (up to the Maximum mark);
12. Then we repeat the procedures with the fitting and pressing the pedal until clean pillbox flows into the bottle;
13. We tighten the fitting and move on to the next wheel.

There is a specific order in which the replacement must be performed. After the left rear wheel, we need the right front, then the left rear and finally the right front. If you started doing everything according to the instructions, then this is the sequence in which the bunker runs.

WHICH LIQUID TO CHOOSE

The technical documentation describes in detail recommendations on what brake fluid to fill in the VAZ 2114. However, many motorists choose the product individually for themselves. Some prefer Bosh bunkers, others Ferodo or TRW. There are many brands of manufacturers with different technical properties to choose from. If the recommended product does not suit you in any way, you can contact a service station for help. There they will describe to you in detail the pros and cons of all famous brands. In our case, DOT-4 synthetic is recommended. This is an excellent brake fluid for VAZ 2114.

When choosing, you can pay attention to the technical properties of the product. The best samples should have high scores in the following parameters:

• Boiling temperature;
• Viscosity;
• Anti-corrosion.

DOT 4 Ferodo
The higher these parameters, the better. Choose wisely.

HOW MUCH TO BUY

The VAZ 2114 system has a volume of 750 milliliters. Taking into account pumping and unforeseen situations, one liter is enough. There will be some left over for topping up. There is no need to carry it with you and constantly top up the pillbox. You can buy it in any quantity at any gas station. Motorists who have been driving for several years can always find out how much brake fluid is in the VAZ2114 system.

It must be remembered that DOT-4 is extremely toxic, so spilling it on open skin is highly undesirable. Therefore, it is not worth storing it in the trunk.

REPLACEMENT

Some drivers don’t even know where to fill the brake fluid in the VAZ 2114 (even though the VAZ brake fluid reservoir is visible), not to mention the rules. DOT-4 needs to be added only if its level in the tank has dropped below the halfway point between the MIN and MAX marks. To do this, simply unscrew the tank cap and fill it to the top mark. The brake fluid volume should not exceed the maximum mark.

Do not under any circumstances mix products from different manufacturers and brands. This may lead to system failure, which will adversely affect your financial situation when contacting the service. Be sure to ask an expert how to add brake fluid.

In general, if all necessary conditions and rules are observed, everything is done quite simply. Any measures to normalize the operation of a car require certain tools and special clothing. This should not be forgotten, since contact with human skin of chemicals contained in fuels and lubricants is extremely dangerous to health.

But whatever one may say, in the quest for durability and reliability of your car there is nothing you can do. The acquired skills can be applied not only to the VAZ 2114, but also to other models of the domestic automobile industry. For example, the VAZ 2115 has an absolutely identical device.

Why do you need a pressure regulator?

Not every owner of a domestic “ten” will understand why the brake pressure regulator on a VAZ 2110 needs to be replaced. Simply, this name is not familiar to everyone. A popular designation for a regulator is a sorcerer.

This very sorcerer is located on the rear suspension of your car. It has a lever with a movable position. Depending on the moment of load on the spring, its position changes.

The voltage generated during actuation is directed and distributed to the brake piston. Pressing the piston pedal reduces the load on the rear pads. If the brake system is working properly, the loads are distributed evenly.

In order for the unit to function efficiently and without errors, it is necessary to adjust the brake pressure regulator on your VAZ 2110. This way you can prevent untimely wheel locking.
