11.1. General information and security measures

General information

All wheels of the cars considered in the present manual are equipped with disk brake mechanisms. The brake disks ventilated. The system of anti-blocking of brakes (ABS) is regularly installed. In addition system of automatic stabilization of stability with the regulator of traction effort / the system of dynamic stabilization of stability (ASC+T/DSC), the ABS systems working at a basis are established.

The brake system is divided according to the diagonal scheme into two independent hydraulic contours and consists of the main brake cylinder (MBC), the vacuum amplifier and brake mechanisms. At refusal of one of contours (for example, as a result of sealing violation) the second continues to function in the normal mode, providing adequate braking of the car. Liquid pressure in both contours is created by the main brake cylinder (MBC) having a tandem design. Activation of GTTs happens when squeezing a pedal of a working brake.

The tank with brake fluid is fixed on GTTs. The amplifier of brakes accumulates a part of the vacuum created in the inlet pipeline of the engine.

The parking brake with the manual lever drive influences through cables the shoe assemblies which are a part of brake mechanisms of back wheels.

Pumping and check of the brake system, and also replacement of brake fluid are described in the Sections Check of the Brake System and Coupling and Replacement of Brake Fluid and Pumping of the Brake System of the Head Nastroyki and routine maintenance of the car.

Security measures

Brake fluid is among highly toxic and chemically aggressive connections and at contact with body panels destroys a paint and varnish covering.

The dust produced in the course of wear of brake shoes may contain unhealthy asbestos of the person, - at all do not inhale it when cleaning brake mechanisms!

Work with the brake system demands special purity and exact observance of instructions. In the absence of necessary experience it is expedient to address on HUNDRED.

At movement along wet roads it is necessary to press periodically a brake pedal for removal of moisture from brake disks; In the course of rotation of a wheel moisture under the influence of centrifugal force is dumped from brake disks, but there is a silicone film, rubber attrition products, lubricant and other pollution reducing efficiency of braking!

The disk brake mechanisms damaged by corrosion when braking create the effect of jolting which is not disappearing over time. In that case it is necessary to replace disks.

Burning of dirt to a surface of brake shoes leads to formation of furrows on a surface of brake disks that leads to decrease in efficiency of braking.
