Removal, check and installation of the amplifier of brakes

Components of installation of the vacuum amplifier of brakes

1 — the Collar
2 — the Vacuum hose
3 — Laying
4 — the Vacuum amplifier

5 — the Bracket
6 — the Returnable spring
7 — the Pin
8 — Shplint
9 — the Holder



  1. Squeeze out a pedal of a working brake several times at the switched-off engine and make sure that the course of a pedal does not change.
  2. Squeeze out a pedal of a brake and start the engine. If the pedal slowly falls, the vacuum amplifier is serviceable.
  3. Start the engine and muffle it through 1÷2 minutes. Slowly squeeze out a brake pedal several times. If the pedal is deeply pressed the first time, and in the second or third attempt its course gradually decreases, the amplifier is tight.
  4. At the working engine squeeze out a pedal of a brake and, without releasing it, muffle the engine. In confirmation of tightness of the vacuum amplifier the pedal should not change the course in 30 seconds of its keeping.



  1. Remove GTTs (see. Section Removal and installation of the tank and main brake cylinder (GTTs)).
  2. Disconnect from the vacuum amplifier a vacuum hose.
  3. Liberate from the holder (9) three tubes.
  4. Remove a returnable spring.
  5. Take шплинт and take out a pin.
  6. Give 4 nuts and remove a bracket.
  7. Remove the amplifier together with laying.



  1. Establish the amplifier with new laying.
  2. Establish on a rod of the amplifier a bracket.
  3. Tighten nuts of fastening of the amplifier with effort of 13 Nanometers.
  4. Insert a pin into a bracket and a pedal of a working brake and fix its shplinty.
  5. Establish a returnable spring of a pedal of a brake.
  6. Establish on GTTs new laying.
  1. Establish on laying the special adaptation and lower an adaptation core till a contact with the piston.
  1. Remove the special adaptation from GTTs and establish on the amplifier.
  1. Measure a gap between a rod of the amplifier and a core of the special adaptation, - it should make 0 mm.
  2. Adjust a ledge of a rod of the amplifier so that his end slightly concerned a core of the special adaptation.

Adjustment make in the absence of the negative pressure attached to the amplifier (for this purpose at the muffled engine several times squeeze out a brake pedal to level pressure in the amplifier with atmospheric pressure).

  1. Establish GTTs, connect to the amplifier a vacuum hose, fix brake lines in the holder.
  2. Fill the tank with brake liquid, pump over brake system and check it on leaks.
  3. Adjust a pedal of a working brake (see. Section Check and adjustment of a course of pedals of the working and parking brake). Make a trial trip.
