Brake system

Management of functioning of brake system is made by means of the double-circuit main brake cylinder (GTTs) of the dual type jointed with the vacuum amplifier (the servo-driver block) brakes.

Forward wheels of the car are equipped with disk brake mechanisms, back - drum-type (with a vertical arrangement of boots). The option of a complete set of all wheels disk mechanisms is possible. For safety reasons contours of lobbies and back brakes are divided and work independently from each other.

The hydraulic system of some models is equipped sensitive to car loading by the valve - the pressure regulator, allowing to avoid premature blocking of back wheels.

The valve is established under the bottom of the car and is connected by a stretching spring to the back bridge.

Into structure of assemblies of disk brake mechanisms enter the brake disk fixed on a nave of a wheel and a support, located on a rotary fist (forward mechanisms), or on assembly of the back bridge. Disk brake mechanisms do not need adjustment.

Drum-type mechanisms consist of the bilateral wheel cylinder which pistons influence for the top ends of brake boots. Bottom parts of boots are fixed motionlessly. Adjustment of drum-type mechanisms is made automatically in the course of braking.

The parking brake is executed in the form of the drum-type assembly established in a back part of transmission and equipped with a hummock drive.

Disk brake mechanisms of models of 4.2 l of EFI late (since 1992) years of release are modified at the expense of application of 2-piston supports and bigger diameter of brake disks. Thus all stated below procedure of repair and service remain invariable. Components of a 2-piston support are shown on an accompanying illustration.
