General information
Vehicles covered in this manual. equipped with front and rear brake systems with hydraulic drive and vacuum booster. Front brakes - disc type, rear - disc. or drums.
The brakes of the front and rear wheels are self-adjusting, i.e. brake pad wear is automatically compensated (for disc brakes). To compensate for the wear of the drum brake pads, there is a special mechanism that is activated every time the brake pedal is pressed or when the hand brake is tightened.
The hydraulic brake system consists of two independent circuits. If one of the circuits of the brake system fails, the second circuit retains its ability to work. There is a warning light on the dashboard. which warns of a drop in the level of the reserve liquid in the tank below the permissible level.
Master cylinder
The master cylinder is bolted to the vacuum booster. The vacuum booster is mounted on the engine bulkhead on the driver's side. Above the master cylinder is a large brake fluid reservoir. This tank is made of plastic and is attached to the cylinder with bushings and a screw. In addition to the brake system, this reservoir also feeds the clutch hydraulic system.
The master cylinder consists of two independent circuits and has independent pistons for the two brake circuits.
Pressure regulator
The pressure regulator is mounted on the engine bulkhead, next to the master cylinder. It is designed to reduce the pressure in the rear brakes during emergency braking (to prevent the rear wheels from locking). Under normal conditions, full pressure is applied to the rear brakes. If this pressure is exceeded in advance, the pressure in the rear brakes is limited.
The pressure regulator is a maintenance-free element of the system. If the valve is defective, it must be replaced.
Vacuum booster
The vacuum booster works due to the vacuum created in the intake manifold, and is designed to reduce the effort on the brake pedal. The booster is installed on the engine bulkhead.
Parking brake
The parking brake is installed on the rear wheel brakes and is actuated by cables. The parking brake is controlled using a lever installed in the passenger compartment. When the parking brake is applied on models with drum rear brakes, cables deploy levers that press the pads against the drum. When the parking brake is applied on models with rear disc brakes, cables deploy levers attached to the screw actuators of the wheel cylinders. These mechanisms move the pistons of the wheel cylinders and the pads are pressed against the brake discs.
Cautions
The following are the most important warnings to read before working on brake system components:
- a) Use only DOT 3 brake fluid.
- b) Asbestos fibers are used in disc and drum brake linings, which can be harmful to your health if inhaled. When working on brake system components, first clean them thoroughly with a brake cleaner. When cleaning brake system components, wear a respirator and do not blow out the brakes with compressed air.
- V) Be very careful and careful when servicing the brake system. Do not use poor quality parts or fasteners. Make sure that all clearances and tightening torques of the connections are correct Technical Data. If you are unsure of your abilities, contact a service station. After carrying out any work on the brake system, before driving on public roads, first check its operation in a safe place.
- G) If there is a malfunction in the brake system, you must stop driving until it is repaired.
