The replacement of brake hoses is regulated differently by each manufacturer, on average it is 3-5 years or approximately 100 thousand km. However, all this is individual, hoses can fail earlier or later, it all depends on the operating conditions and the quality of the brake hoses themselves. From time to time you should carry out a visual inspection of the hoses, and the entire vehicle as a whole, this is the only way you can avoid troubles on the road.

The appearance of microcracks in rubber hoses or metal tubes is a reason to immediately replace the brake hose or part of the damaged line. Damage to the tightness of the line manifests itself in different ways, but one thing will always remain the same - the absence of brakes, that is, when you press the pedal, it will fail, and the car will not stop. Damage to the hose can also be detected by a wet trail after a long period of parking.

new fluid, it is recommended to pay attention to the DOT-4 class.

Tube installation design

The front tube runs from the brake master cylinder under the engine hood.

Replacing the brake pipe of a VAZ 2109

The brake cylinder has two working compartments.
The front brake system pipes are installed in the compartment located first from the vacuum booster.
The left tube is in a free position, mounted on the front pillar along with a rubber hose.
The tube for the right wheel is fixed to the partition separating the engine compartment from the passenger compartment.
At the attachment point, two more tubes pass to the rear cylinders. They are attached to a screw hinge using one strip and a nut.
The right tube has a second mount, below under the car body.

The work of replacing tubes is carried out in a garage with an inspection pit.

Work procedure

Rear brake pipes VAZ 2109

Before you take action, you need to prepare first. During the preparatory work, it is necessary to clean the surface of the fitting tubes from contamination. You also need to apply a special compound to all threaded connections, this will make it much easier to unscrew the nuts. In addition, you need to prepare a wrench, spare brake fluid for topping up, a small container to drain the remaining fluid from the system and a suitable vinyl tube. For convenient repairs, it is recommended to install the machine either on an overpass or on a pit for inspection:

First, use a Phillips screwdriver to unscrew two self-tapping screws that secure the tube to the body of the vase.
Using a suitable wrench, unscrew the 2 fittings through which the tubes are attached to the hose with the regulator.
The tube is removed.
After all necessary work has been carried out, the tubes are installed in the opposite order to dismantling.
Add brake fluid.
The quality of repaired brakes is checked.

On newer VAZ models, the tubes are first unscrewed from the main cylinder and brake hose, only after that the holes are plugged. In this case, you will have to unscrew the 3 fastening nuts and remove the plastic covering. Next, dismantle the metal plates and disconnect the necessary tubes from the clamps; if they are damaged, they will need to be replaced.

Signs of air penetration into the system are considered to be increased travel and softened sagging of the brake pedal when pressed. It is necessary to follow a certain sequence of bleeding the brakes:

rear right;
front left;
rear left;
front right.

In addition to changing the brake line, the brake hose may also need to be replaced.

What causes brake lines to become sour?

In the initial state, the nut has an anti-corrosion coating, but the tightening torque is such that its integrity is broken and direct metal-to-metal contact is formed. In order to reduce the cost of construction, both mating parts are made of iron alloys, which are easily subject to corrosion when in contact with oxygen and moisture.

In addition to the external influence of substances aggressive to iron, internal factors can also play a role. This is the ingress of decomposition products of brake fluid components and galvanic effects due to the combination of various metals in one contact.

The result is always the same - corrosion products accumulate between the turns of the thread, which have a significant volume and push the thread apart with great force. It becomes impossible to unscrew it using conventional methods.

In addition to souring of the thread, sticking of the brake pipe to the union nut also occurs. If the tube needs to be replaced, then this does not play any role, but when you try to preserve the original part, difficulties begin. Even when the nut begins to rotate, turning the tube together with it does not allow making even one full turn.

How to repair brake pipes

This process requires the car enthusiast to have extensive locksmith skills and the ability to use special tools. Repairs are carried out in cases where it is not possible to replace the damaged line; it involves saving money on the purchase of a new pipe system and extends the service life of the old one.

To carry out repairs you must:

1. Unscrew the damaged tube from the cylinder or brake caliper.

2. After disconnecting, it is necessary to cut off the damaged area using a pipe cutter.

3. Clamp the tube 50 millimeters from the edge of the cut and chamfer the edge of the tube using a drill.

4. Remove all that remains of the chips and insert a fitting intended for connecting the tube to the brake operating mechanism into the cut area.

5. Insert the end of the tube into the special equipment and flare it. The main line that has undergone repairs must be purged with compressed air. And only after this is it installed with a working mechanism or another pipeline system using an adapter.

As for the length of the tube, this parameter depends on the car model. On some cars, the brake pipes have a reserve that allows you to shorten the pipe and reconnect it to the working mechanism. The metal from which the brake tube is made is flexible, so there should not be any difficulties with its position.

What to do to prevent brake pipes from souring in the future

There is no universal recipe here, it all depends on the time. But the use of penetrating anti-corrosion compounds for hidden body cavities, which envelop parts, prevent the development of corrosion due to the inhibitors contained in the composition, and do not allow water and oxygen to pass through to the threads, helps a lot.

The connection of the tube, nut and mating part is generously moistened with one of these compounds. After drying, they remain in a fairly elastic state.

On top of this treatment, you can apply a layer of protection with more durable characteristics. These can be compositions such as anti-gravel or other body sealants. If necessary, they are easily removed.

Before screwing, the thread itself is coated with a special lubricant containing finely dispersed copper. Such auto chemical goods have recently been widely used during repair installations, significantly facilitating subsequent unscrewing.

When control sensors indicate a breakdown of the brake system

The “breakdown” symbol appears on the control panel if there is a low level of brake fluid in the reservoir, then you need to plan to bleed the system and decide how to replace the brake hoses on a VAZ 2114 yourself or with the help of a specialist.
There is also a sign on the panel that the parking brake is engaged. It must be turned off at the moment you start moving, otherwise damage cannot be avoided, and then all the problems will follow each other, and a situation will arise with a solution to the question of how to replace brake hoses on a VAZ 2114.

Thus, vigilance and vigilance again are the main things that the driver must remember when entering the garage and while driving along the route every day and every second. It’s better to sit down and figure out how to replace brake hoses on a VAZ 2114 than to experience stress at speed when the brake pedal simply falls under your foot and the car does not stop on demand.

Let us remind you how to check the condition of the brake system without leaving the garage.

A situation arises when the engine is idling and the gear lever is in neutral. The driver must press the brake pedal and hold it in this position for several minutes. If the pedal fails very easily, then there is reason to suspect that there is a malfunction in the system. You need to think about how to replace brake hoses on a VAZ 2114, which specialist you should trust to solve an important issue.
The contents of the master brake cylinder are checked regularly; if the fluid level drops, you need to sound the alarm and take the car to a service station using an emergency light. Even if there is a slight decrease in the level of contents in the tank, this condition can still be considered a sign of wear on the brake system components. This means that you need to decide how to replace brake hoses or pads on a VAZ 2114. If you notice the rapid disappearance of liquid from the barrel in a short period of time, this means that there is a leak, and it is strictly prohibited to drive such a machine. We remind you that depressurization of the system can be internal or external, and the first can only be recognized by the condition of the tank, while the second leaves its traces in the area of the wheel mechanisms.

Brake fluid VAZ 2114
An important rule for a novice driver is to learn how to check the condition of the hydraulic and parking brakes. It wouldn't hurt to know how to regulate them. And the aerobatics for a newbie in the car industry is to know how to replace brake hoses on a VAZ 2114, especially since this car brand is a debut for many.
It is imperative to inspect the condition of the wheels and “adjacent areas” before leaving. If you notice dampness on the surface being inspected, react immediately - check and figure out how to replace brake hoses on a VAZ 2114.
Beginners should also study the control panel inside the car. Sensors there are always triggered if any of the important parts are worn out or suddenly fail. Always pay attention to the brake warning lights. So, for example, at the moment the ignition signal is given, the brake warning lamp should be on, and go out when the car is started and begins to move. Then everything is in order and you don’t have to think about how to replace the brake hoses on a VAZ 2114 this time.

Required Tools

In order to replace the brake cylinder you will need the following tools:

wheel wrench;
jack;
WD-40;
socket wrench 10;
a device for unscrewing fittings if necessary;
metal brush;
rags;
pliers;
a screwdriver or pin for tensioning the springs.

Before starting all types of work, be sure to provide a place for laying out all spare parts; when removing them, it is advisable to remember the sequence and methods of removing them. This will make the reverse process much easier. In addition, before such a procedure, it is advisable to stock up on a set of brake pads, because they still need to be changed every year depending on the intensity of driving. And besides, they don't cost that much. So, having everything listed in our arsenal, let's get to work.

REAR BRAKE CYLINDER

The working rear brake cylinder on a VAZ is a device in which two pistons, under pressure created by the liquid, push the rear pads apart. The pads are pressed against the drums and braking occurs.

The rear brake cylinder for 2114 (ZTC) can be of different manufactures. In Russia there are quite a lot of enterprises specializing in the production of spare parts for cars. The original parts are produced by AvtoVAZ; many spare parts for VAZ cars are produced in Samara. But there are also products from other companies (including foreign ones):

Ate, Germany;
Samco, Italy;
Lucas;
Fenox;
AP Lockheed;
"Basalt";
"Craft".

ZTC Kraft
Among all the listed companies, according to customer reviews, the products of ATE have proven themselves the best. Among Russian brands you can about

Depending on the manufacturer and region of sale, the price of a cylinder on average ranges from 250 to 700 rubles (as of 2105). There is no difference between the VAZ 2114 and VAZ 2115 models; the parts are completely interchangeable with each other.

On a fully assembled car, it is not visible where the rear brake cylinder is located; it is located inside the rear drum. But you can understand where it is by looking at the brake pipe that goes to the cylinder.

What brake hoses should I buy and what spare parts should I buy to replace the brake hoses?

Brake hoses have proven themselves well , they are of good quality and a little expensive. If you want to save a little, you can buy brake hoses produced by DAAZ , which are also of good quality.

You should also buy copper washers 1.5 mm thick, brake fluid, which is necessary for bleeding the brake system. I recommend buying brake fluid DOT 4 400 grams.

Do-it-yourself replacement of brake hoses on a VAZ 2115

A properly functioning brake system is the key to your safety! I talked about this a long time ago, in one of my previous articles. Today I am no less confident in this, and I want to talk about brake hoses, or more precisely, about how to replace them on a VAZ 2115.

Only regular maintenance and monitoring of all components of the brake system can provide confidence that the brakes will not fail at the most inopportune moment. One of the most important components of the brake system (BS) is the line through which the brake fluid (FL) is delivered to the brake cylinder and calipers. A leak in one of the hoses can lead to a malfunction of the vehicle, as a result of which the fuel fluid will leak out, and you will simply find yourself without brakes.
