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 should be displaced a little forward.

Tightness check

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

Removal

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

PERFORMANCE ORDER
1. Remove the main cylinder.
2. Remove a podkolennik from the driver and find a fork of a pusher of the amplifier (shooters are specified шплинты axes of a fork of a pusher and a nut of fastening of the amplifier of brakes).
3. Rasshplintuyte fork axis.
4. Holding a pusher fork, release a fork lock-nut.
5. Disconnect from the amplifier of brakes a hose.
6. Unscrew four nuts of fastening of the amplifier of brakes to a partition of a motor compartment.
7. Carefully submit 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 established, 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 piston dredging. It is the size C.
6. The gap between a pusher and the piston is equal (In – C) – And and should be equal 0.
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 establish 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.
