Servo
Check
| PERFORMANCE ORDER | | Verifying | | 1. Depress the pedal and start the engine. If the pedal is slightly lowered, then booster is defective. | | 2. Depress the brake pedal several times with the engine running and check to reserve the brake pedal travel has always been the same. | | Leak test | | 3. Start the engine and stop it after a couple of minutes. Slowly depress the brake pedal several times. Stroke of the brake pedal should decrease each time. | | 4. Depress the brake pedal with the engine running, then shut off the engine, hold the brake pedal. If the pedal does not drop within 30 seconds, then booster is sealed. |

Withdrawal
| PERFORMANCE ORDER | | 1. Remove the brake master cylinder. Disconnect the vacuum hose from the amplifier. | | 2. Disconnect the pushrod from the brake pedal. |  | 3. Unscrew the four nuts and remove the amplifier. |
|
Setting
| PERFORMANCE ORDER | | 1. Installation is spent upside-down removals. | | 2. Connect the vacuum pump to an amplifier and create a negative pressure of 500 mm Hg. |  | 3. Measure the distance from the servo to the pusher - the distance "A". |  | 4. Measure the distance from the mounting flange to the end of the master cylinder - the distance "B". |  | 5. Measure the distance from the end of the master cylinder to the recess in the piston - is the distance "B". | | 6. Subtract the value of "B" from the value of "B", subtract the value obtained from the value of "A". The result is the value of the gap servo pusher. |  | 7. Adjust the length of the pusher (1), if necessary by loosening the lock nut (2) and tighten up control pusher. |
