Brake fluid for VAZ 2114: selection, replacement

According to statistics from the European Motorists' Community (ECA) for 2015 - 2021, 23% of accidents are caused by a faulty brake system.

Owners often underestimate the importance of brake circuit prevention (hereinafter referred to as TC). Late replacement of friction linings, late fluid renewal and monitoring of fluid levels are the most common factors.

The process of independently servicing the fuel tank and replacing the fluid is not at all difficult, but it requires attentiveness on the part of the technician. Violation of the regulations is unacceptable.

What brake fluid should be used in a VAZ 2114 car

According to the manufacturer's recommendations, set out in the VAZ 2114 operating instructions, the “update” of the TZ is carried out every three years or 45 – 50 thousand km, whichever comes first.

Since 1995, DOT-4 has been added to the brake circuit. Previous classes were canceled due to ineffectiveness and non-compliance with standards.

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.

What is the function of brake fluid

The brake fluid transfers kinetic energy from the cylinder to the pads when the brake pedal is pressed. The length of the braking distance required to completely stop the car depends on the completeness and timeliness of the transfer of pressure.

Often an old car leads to brake failure. Which is extremely dangerous when driving at high speeds.

You can update the TZ yourself; it is not at all necessary to contact a service station if the factory warranty has already expired.

Note to the driver!!! DOT-4 is an aggressive liquid; if it comes into contact with the skin of the hands, it can cause an allergenic reaction. Be extremely attentive and careful. Don't forget rubber gloves.

How much lubricant is in the circuit: the volume of lubricant in a VAZ 2114 car is 1.0 liter. Buy one and a half liters so that you always have a supply of bunkers at hand. The manufacturer of the bunker is not important, the main thing is that the liquid is class four.

The most popular are American and European brands, namely: Castrol, Liquid Moly, Shell, Mobile, Neva, DOTs.

To replace you will need:

new DOT-4;
plastic container for draining waste;
rubber hose to change the “lubricant”;
key to “10”;
rags;
additional lighting;
new rubber boots on the working cylinders if the previous ones have become unusable.

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.

Welcome! Brake fluid - and it’s the only thing that slows down the car, although not everyone knows this, but in fact, only this fluid stops your car when you are rushing at high speed and you need to stop quickly. From what you read above, you understood that brake fluid is very necessary for a car, because if it weren’t for it, the car would not be able to be stopped at all (Not counting the hand brake, it only works by hand, that is, mechanically, and brake fluid for it is not needed at all), so this liquid must be changed periodically, since any liquid ages and thereby loses its properties.

Note! To change the brake fluid on a Samara 2 family car, you will need to stock up on: Be sure to have a set of wrenches or a set of spanners that will include a wrench of about 8 or 10, and you will also need to take with you a short hose with a diameter of 6 mm, and you will also need to stock up on a transparent bottle, it is best to use a bottle with a plastic body!

Summary:

When should you change your brake fluid? First, let's look at the timing and only then move on to the moments of how the car will behave with spoiled fluid, in general, let's start with the timing first. If you believe the regulations, it states that this liquid must be changed every 2-3 years, because from time to time moisture gets into the liquid and therefore the liquid is diluted with water, and because of this it can simply freeze in winter (Pedal In this case, the brakes will be hard, and thus the car will slow down worse when you press the pedal), and liquid diluted with water is prone to boiling after long braking, especially in the summer (the pedal in this case will be soft and the car will also brake worse).

Now let's get closer to the mileage, that is, the frequency of replacing brake fluid by mileage; for passenger cars, this frequency mainly rests on the mark of 30,000-40,000 thousand km, and it is with this frequency that the brake fluid needs to be replaced.

Note! For more information about the timing of replacing this fluid, look in your service book, everything is detailed there, what needs to be replaced and when!

What will happen if the brake fluid deteriorates, we are often asked such questions, there are answers to them a little higher, but still we will note a few nuances when the car’s brakes are getting worse and worse every day and you haven’t climbed into the car before and If your brake pads do not creak, this only means that the fluid is gradually beginning to lose its properties, immediately after detecting poor braking, unscrew the lid of the brake reservoir and look at the color of the fluid in it, it should be transparent, or at least a little dark sometimes even happens because different dyes are added to the liquid so it can be red and yellow, so if you open the lid of the tank and find that your liquid is no longer so transparent, but is all cloudy and there is sediment at the bottom or top , then in this case this fluid must be immediately replaced with a new one.

How to properly fill brake fluid on a VAZ 2114

The procedure for replacing the TJ is as follows:

Place the car on a roadside overpass (inspection hole);
Open the hood, unscrew the cap from the expansion tank of the master brake cylinder;
If necessary, remove the wheel after hanging the car;
Ask your partner to bleed the brake pedal and hold it in the down position;
Remove the rubber cap on the working cylinder, put the hose on the grease fitting, and lower the end into a plastic container;
Using the key “10”, unscrew the grease fitting, drain the fuel fluid, tighten the valve;
Repeat the pumping procedure until clear DOT-4 liquid flows from the hose.

In practice, 3–4 flushes are enough to update the system. At the same time, do not forget to replenish the missing amount of DOT - 4 in the expansion tank after each cycle. Otherwise, you risk introducing air into the system, which is extremely undesirable and dangerous.

After updating the contour of one slave cylinder, move on to the next one. Don't forget about the diagonal principle. DIY replacement completed.

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.

Signs of brake fluid loss of quality

Increasing the length of the path to a complete stop of the car;
Pressing the brake pedal requires force;
The pillbox in the expansion tank changed color from light to dark;
At the place where the tank is installed, traces of lubricant leakage are visible, the level is below normal;
The yellow indicator light is on on the dashboard.

If one or more signs are detected, stop the car, turn off the engine, and inspect the brake circuit and master cylinder. If traces of depressurization of the circuit are visible, then call a tow truck to deliver the car to a service center. Subsequent operation of the technical device is unsafe.

Recommendations for servicing the brake circuit of the VAZ 2114

Conduct scheduled technical inspections of the vehicle in a timely manner;
When purchasing, carefully check the catalog numbers with the data specified in the instruction manual;
Use the services of certified points of sale.

Service station experts recommend purchasing DOT-4 on semi-synthetic and synthetic bases. It is “synthetics” that meets many modern requirements and quality standards.

Mineral-based lubricants are not always effective for high speed conditions and systematic loads. If you have any difficulties choosing a technical vehicle for a VAZ 2114, contact service station specialists and auto store managers for help.

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.

Change brake fluid immediately - if necessary
