GENERAL INFORMATION

The vacuum amplifier of brakes reduces effort on a brake pedal, facilitating thereby driving. Operation of the vacuum amplifier of brakes is based on depression use in an inlet collector. At an exit of the vacuum amplifier out of operation operability of brake system is not broken, but for pressing of a pedal of a brake it is necessary to make the bigger effort is considerable.

Check

PERFORMANCE ORDER
1. Press a brake pedal several times at the idle engine to create in cavities of the vacuum amplifier identical pressure close to the atmospheric.
2. At the same time on the effort enclosed to a pedal, define, whether there is no jamming of the case of the valve.
3. Stop a brake pedal in the middle of its course and start the engine.
4. At the serviceable vacuum amplifier the brake pedal after start of the engine should leave forward.
5. If the pedal does not leave forward, check fastening of a tip of a hose, connection of fastening of a flange of a tip in the amplifier, a hose and union condition.
6. On cars with diesel engines check operability of the vacuum pump.

Removal

PERFORMANCE ORDER
Cars for right-hand movement
1. Disconnect a vacuum hose from the vacuum amplifier of brakes.
2. Unscrew the nuts, fixing the main brake cylinder to the vacuum amplifier of brakes.
3. Remove the main brake cylinder from racks of the vacuum amplifier of brakes and move forward, without deforming thus brake tubes.
4. In salon of the car remove the switch of stoplights from an arm of a pedal of a brake.
5. Remove a spring bracket from the sharnirny finger, a pusher of the vacuum amplifier of brakes fixing a fork to a brake pedal.
6. Remove a sharnirny finger.
7. Remove a fairing located in the lower part of a windscreen, then remove screen wiper levers, the engine and drafts of a screen wiper.
8. Remove two caps closing bolts of fastening of the vacuum amplifier of brakes.
9. Using a face key, unscrew bolts and remove the vacuum amplifier from a partition of a motor compartment.
10. If access to bolts of fastening of the vacuum amplifier is complicated, it is possible to unscrew four nuts of fastening of an arm of the vacuum amplifier to a partition of a motor compartment.
11. Remove the vacuum amplifier of brakes from the car.
Cars for left foreign movement
12. Operations on removal of the vacuum amplifier of brakes are similar stated above.
13. Turn off three nuts of fastening of the vacuum amplifier of brakes on cars with left foreign movement.
14. For access to the bottom nut of fastening of the vacuum amplifier without removal of steering transfer it is necessary to use a natural adapters.

Installation

PERFORMANCE ORDER
1. At installation of the new vacuum amplifier of brakes rearrange on it with old a collar and a lock-nut.
2. Before installation of the vacuum amplifier of brakes check length of a rod with a fork.
3. Measure distance And from an end face of the case of the vacuum amplifier of brakes to the opening center in a fork which should make 278,5 mm.
4. Further installation is made in sequence, return to removal taking into account the next moments.
5. If the vacuum amplifier of brakes acted in film from an arm, establish it on hermetic.
6. Check that the place for connection of a vacuum hose (it is specified by an arrow) is in demanded situation.
7. For fastening use new самоконтрящиеся nuts.
