Work check

PERFORMANCE ORDER
1. Press several times a brake pedal on the idle engine. The pedal course by each pressing should not change.
2. Press a pedal and start the engine, – the pedal has to be displaced a little forward.

Tightness check

PERFORMANCE ORDER
1. Start the engine, 1–2 min. later stop.
2. Slowly press a pedal several times, – the course of a pedal has to decrease gradually.
3. Start the engine and press a pedal.
4. Holding a pedal of pressed, stop the engine, – during 30 sec. after a stop the provision of a pedal should not change.

Removal

If the amplifier is faulty, then he will lie down to replacement, repair of the unit is impossible even in the conditions of car service.

PERFORMANCE ORDER
1. Remove the main cylinder.
2. Remove a kneeboard from the driver and find a fork of a pusher of the amplifier (shooters specified forelocks of an axis of a fork of a pusher and nut of fastening of the amplifier of brakes).
3. Rasshplintuyte fork axis.
4. Holding a pusher fork, release a fork lock-nut.
5. Disconnect a hose from the amplifier of brakes.
6. Turn off four nuts of fastening of the amplifier of brakes to a partition of a motor compartment.
7. Carefully give the amplifier and remove when hairpins leave a partition.

Installation

PERFORMANCE ORDER
1. Installation is carried out upside-down.
2. If the new unit is installed, then adjust a vystupaniye of a pusher of the main cylinder over the case of the amplifier. For this purpose execute the following.
3. Measure a pusher vystupaniye. It is the size A.
4. Measure distance from an end face of the main cylinder to a flange. It is the size B.
5. Measure distance from a cylinder end face to the bottom of dredging of the piston. It is the size C.
6. The gap between a pusher and the piston is equal (In – C) – And yes 0 has to be equal.
7. Rotating a pusher tip, establish such vystupaniye And that the gap was equal In – S. Snova check a gap.
8. If necessary repeat adjustment.
9. Upon termination of install the main cylinder, attach tubes, adjust height of a pedal and a free wheeling (see subsection 2.34).
10. Remove air from a hydraulic actuator.
