The vacuum amplifier of a brake
For revealing of the possible reasons низкоэффективной works of brake system owing to defects of the vacuum amplifier it is necessary to spend following works.
| PERFORMANCE ORDER |
| 1. At the idle engine 4 - 5 times press a pedal of a brake and leave a pedal pressed. |
| 2. Start the engine. In process of increase of number of turns easing of influence of a pedal on a foot that specifies in occurrence in the vacuum amplifier should be felt. |
| 3. Allow to work to the engine of 2 minutes and stop it. |
| 4. Press a brake pedal (ask the assistant) and put an ear probably more close to the vacuum amplifier. By pressing a pedal "the hissing" accompanying process of formation of vacuum should be audible. The sound disappears after 4 - 5 pressing a pedal. |

Removal
Kind of the vacuum amplifier of a brake
Explanatories are resulted in positions in the text.
| PERFORMANCE ORDER |
| 1. Removal of the vacuum amplifier is made according to иллюстрациейВид the vacuum amplifier of a brake. Thus the description concerns model from the middle of 1995 of release. On earlier models removal process is carried out similarly. |
| 2. Disconnect a cable of weight from the storage battery. |
| 3. Remove the main brake cylinder (1) as it is described for the car of corresponding year of release. |
| 4. Ослабьте a collar also remove a vacuum hose (2) from a branch pipe on the vacuum amplifier. |
| 5. Disconnect from outside salon a plug (3) from a brake pedal. For this purpose remove a spring clip from the end of a finger of a pusher. |
| 6. Turn away four nuts of fastening (4) amplifiers (5) from a forward wall of an impellent compartment. To turn away the bottom nut it is possible with the help шарнирной heads with the extension piece. |
| 7. Take out the amplifier from an impellent compartment, in appropriate way having developed it. |
|
External details of the vacuum amplifier
At repair the details shown on an illustration are subject to replacement only. Explanatories are resulted in positions in the text.
| PERFORMANCE ORDER |
| 1. Turn away a counternut (2) and a plug (1). |
| 2. Remove a clip (3). |
| 3. Remove a protective cover (4) cases of the valve. |
| 4. Remove the shock-absorber (5). |
| 5. Remove the filter (6), two consolidations and one remote washer (7). |
| 6. A screw-driver remove the holder (8) on other party of the amplifier of a brake and squeeze out a lath and consolidation (9). |
|
Before installation of any details it is necessary to check up a plug, a protective cover, the shock-absorber, the filter and a lath with consolidation and if necessary to replace them.
Assemblage
Assemblage is carried out according to an illustration External details of the vacuum amplifier in the shown sequence. The nut of fastening of a plug is tightened by the moment of 20 Nanometers.
Installation of the vacuum amplifier is carried out in the way described more low. If the vacuum amplifier is replaced, it should be adjusted. Thus it is necessary to distinguish old and new executions:
| PERFORMANCE ORDER |
| 1. Establish the vacuum amplifier and fix its nuts. On the car to the middle of 1995 of release of a nut tighten the moment of 21 Nanometers. |
| 2. At putting on of a vacuum hose it is necessary to pay attention to an arrow direction on a hose. The arrow should specify towards the engine. |
| 3. Other works are spent to sequences, return to removal. |
| 4. In summary check up working capacity of the vacuum pump as it is described in the beginning of the present section. |
|
If the vacuum amplifier was replaced with the new
If the vacuum amplifier of a new series from the middle of 1995 of release was replaced, it is impossible to adjust a pusher usual means, since. The vacuum pump and calibre for this purpose are required. Here it is necessary to hope only that adjustment of the removed detail corresponds to adjustment of a new detail.
| |
At the car of a back issue the pusher can be measured and adjusted. The acting part of a pusher from a flange plane on the vacuum amplifier till the end of a pusher is measured. On an illustration it is the size "And". If this size falls outside the limits 18.0 - 18.2 mm, the pusher counternut is weakened also a pusher turns. The nut is tightened by the moment of 27 Nanometers. |
