The brake system is hydraulic with a hydraulic vacuum booster, dual-circuit. Master brake cylinder and hydraulic booster «dozens» the same as in «nines».
«Dozens» have three types of front brakes.
On a VAZ-2110 car, a brake disc, a caliper, a pad guide and a protective cover from 2108 are installed.
On a VAZ-21102 car, a ventilated disc with an index of 2110, a caliper 2110, pad guides 2110 and a protective casing 2112 are installed.
On VAZ-21103, VAZ-21113 and VAZ-2112 vehicles, the following are installed: a ventilated disc with an increased diameter of 2112, the caliper is the same for everyone - 2110, the shoe guide is its own - 2112 and a protective casing 2112. Ventilated front brake discs have an internal hole through which it cools the disk is still inside.
Practice shows that ventilated brakes, and especially those with larger discs, are much more effective than «Samara». Translate «Samara» brakes on brakes «Lada-112» it is possible, but for this you need to have all the equipment of the front brakes «Lada-112». But you should always remember: brakes with large diameter discs need a 14-inch wheel.
The brake mechanisms of the rear wheels are similar to the brake mechanisms of the family «dozen».
Parking brake
The parking brake device is almost the same not only on domestic cars, but also on imported ones. But, given the importance of the parking brake, which many drivers forget, you should pay attention to its operation.
When the parking brake lever is lifted up, the cable pulls on the special lever of the rear brake mechanism parking drive, the pads are pressed against the brake drum, visual forces are created between the pads and the drum, and the kinetic energy of the car is converted into thermal energy of the brake mechanism. This is how the parking brake works, it is used when the car is parked on a hill, when the car is braking on a slippery road, when braking with a service brake leads to a skid or skid of the car. Well, its main purpose, which you need to remember, is that it acts as a spare brake. When the service brake fails, when its pedal fails, immediately the right hand should pull the parking brake lever up.
The parking brake cable is located in a casing, the ends of which are closed with caps. It is necessary to monitor their condition, they should not have cracks. If they appear, moisture will get into them, the cable will rust and will not move. Before the caps, the cable must be lubricated.
When tensioning the cable, it must not be overtightened; there should be at least 4-5 clicks when the brake lever is raised. A tight cable limits the operation of the pads even when the service brake is operating. We must remember this.
Brake hoses and fluid
We have just considered the actions of the driver in the event of a sudden failure of the brake pedal. The reason for this can basically only be a rupture of the brake hose. Other elements that are out of order, as a rule, tell the driver: this element needs to be changed. This clue may be brake fluid leaks on the wheels and on the road, a decrease in fluid in the reservoir.
Therefore, every self-respecting driver who cares about the health of his «friend» and about the safety of himself and his passengers, he must regularly monitor not only the level of brake fluid in the reservoir, but also the condition of the brake hoses and the presence of brake fluid leaks.
The working conditions of the brake hoses, and other elements of the brake mechanisms are quite difficult. Water, dirt, ice, salt, sand, stones, as well as internal pressure and vibrations, constantly put almost all elements of the brake mechanism to the test during operation. And brake hoses are additionally subjected to bending and twisting both during operation and during the repair of all elements of the brake system.
If the old hose failed, you did not pay attention that it cracked, there are cracks or cuts, you were waiting for better times to replace, the driver is to blame. But if you only replaced the old hose without cracks and cuts, which served faithfully for almost ten years, with a new and clean one, you didn’t manage to drive even a hundred kilometers on it, when you had to apply your art in managing your «friend», when his pedal failed so as not to crash the car... - It's a shame and it hurts, especially because such cases were less common before.
When choosing brake hoses at the time of purchase, be very careful and pay attention to the inscriptions, they must be of high quality (it is desirable that the manufacturer is known) and should not stretch out.
Brake fluids also play a significant role, so it is important to know their name, what is their quality and who made them.
To the brake system «dozens» filled with brake fluid such as DOT-3 or DOT-4, ROSA, ROSA-3, ROSA-DOT-4 and so on - they are indicated in the instruction manual. Of the imported ones, the following are interchangeable with them: Motul DOT-4, Castrol DOT-4.
