General information about the brake system According to its purpose and functions, the brake system includes working, spare, parking and emergency systems. The service brake system regulates the speed of the vehicle and stops it with the necessary efficiency....
Brake system technical data Below in table. 11.1 shows the general, adjustment and reference data of the brake system, and in table. 11.2 - tightening torques of the main threaded connections.
Anti-Lock Braking System (ABS) Braking efficiency is greatest when the grip of the tire with the road surface is maximum. During braking, the tire slides on the surface, and the speed of rotation of the wheel becomes less than the speed of the car....
Elements of the anti-lock braking system Modulator It consists of an electric pump and four solenoid valves. An electric pump pressurizes and fills the reservoirs in the modulator. The pump and reservoirs are located in the modulator block. Solenoid valves...
Removal and installation of elements of anti-blocking system of brakes ABS modulator Pic. 11.10. ABS modulator for models up to 2001 (modulator of 1996 4WD models has minor differences): 1 - bolt; 2, 4 - pillow; 3 – ABS modulator; 5 – modulator bracket; 6 – a reservoir of the amplifier of...
Replacing the front brake pads Attention! Be sure to replace all pads on the same vehicle axle, even if only one pad is worn. If the brake pads will be reinstalled, mark them before removal. Warning! Brake pads generate brake dust, which contains...
Replacing the front brake caliper Warning! Brake pads generate brake dust, which contains asbestos, which is harmful to health, so do not use compressed air or inhale the dust when cleaning brake pads. Attention! To clean the brake mechanisms, use only...
Check and replacement of brake disks — removal, check and installation Attention! If one brake disc needs to be replaced, replace both to ensure uniform braking. When replacing the brake discs, also replace the brake pads. Examination Apply the parking brake and chock the rear wheels....
Replacing the rear brake pads Attention! Be sure to replace all pads on the same vehicle axle, even if only one pad is worn. If the brake pads will be reinstalled, mark them before removing them. Warning! Brake pads generate dust that contains...
Replacement of the working brake cylinder Attention! Be sure to replace the working brake cylinders in pairs, even if only one brake cylinder has failed. Note. If there are brake fluid leaks from the working brake cylinder, it is recommended to replace it...
Replacing the master brake cylinder Removing On models before 2001, remove the air filter cover and the fuse and relay box from the left side of the engine compartment. Pic. 11.35. Master brake cylinder: A - electrical connector; B - places of connection...
Replacing the O-rings of the brake reservoir The brake reservoir can be replaced without removing the brake master cylinder. If there are brake fluid leaks between the brake master cylinder and the reservoir, replace the reservoir o-rings. Remove the cap from the...
Replacement of brake pipes and hoses Brake pipes and hoses are used to supply brake fluid from the master brake cylinder to the working brake cylinders. Pipes are connected to brake cylinders and distributing devices by union nuts. The ends of the tubes...
Bleeding hydraulic brake drive Bleeding the hydraulic brake drive is necessary to remove air, which significantly reduces braking efficiency. Air can get into the hydraulic drive due to depressurization of the system when repairing or replacing the...
Checking and replacing the vacuum brake booster Examination The vacuum brake booster increases the force applied to the brake pedal, thereby making driving easier. The principle of operation of the vacuum brake booster is based on the use of vacuum in the intake...
Parking brake adjustment If, when tightening the parking brake lever to the stop, it goes from 5 to 8 clicks, then the adjustment is correct. If the stroke is less than 5 clicks, then the brake pads will be partially pressed against the brake...
Replacing the parking brake cables Rear cable replacement The rear parking brake cable connects the rear wheel brakes to the compensator. Relieve pressure in the fuel system and disconnect the wire «masses» from the battery. Block the front wheels with...
