12.13. A servoamplifier of brakes - check, removal and installation

1. Squeeze out a brake pedal some times at the switched off engine and check up, that the course of a pedal of a brake did not change.

2. Squeeze out a pedal of a brake and start the engine. If the pedal hardly has fallen, means, the servoamplifier is serviceable.

3.  Start the engine and allow to it to work one-two minutes. Slowly squeeze out a brake pedal some times. If the course of a pedal of a brake gradually decreases, means, the servoamplifier is tight.

4. Squeeze out a brake pedal when the engine works, then muffle the engine, not releasing a brake pedal. If the pedal does not fall within 30 seconds, means, the servoamplifier is tight.

5. The servoamplifier is not subject to repair. If it has failed, it is necessary to replace it.

6.  For  servoamplifier removal  remove the main brake cylinder.

12.7 Get to the check and a pin, then turn off Fixing nuts of a servoamplifier (are specified by arrows) (model Precis is shown - the others are similar) 9. Ask to press the assistant a brake pedal some times, then to squeeze out a pedal up to the end.

7. Find the pusher plug, connecting the amplifier with a pedal of a brake (12.7).

8. Get to the check and remove a plug pin.

9.   Keeping  a plug  flat-nose pliers,  turn off a counternut and disconnect a plug.

10. Disconnect a vacuum hose from the amplifier.

11.  Turn off four nuts and remove washers (12.7).

12. Remove the amplifier from a back wall of an impellent compartment.

13. Installation is spent upside-down removals.

14. Measure and adjust a backlash between the piston of the main cylinder and a servoamplifier pusher

12.14а the Backlash between a pusher of a servoamplifier and the piston of the main brake cylinder should be such as it is specified in section of technical characteristics-. If the backlash is too small, brake overlays will not depart from a disk; if the backlash is too great, the brake pedal will have excessively free course 1. A backlash

12.14б For adjustment of length of a pusher of a servoamplifier keep a pusher flat-nose pliers and tighten up an adjusting nut

Tighten up an adjusting nut (it is specified by an arrow) for correct adjustment of a course of the lever of a manual brake (is shown model Galant) (12.14а and 12.14б), having tightened up an adjusting nut on the end of a pusher of a servoamplifier.

15. On termination of installation of the main cylinder and a servoamplifier pump over brake system.
