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 — the Lining
4 — the Vacuum amplifier

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

Check

 PERFORMANCE ORDER

  1. Squeeze out a pedal of a working brake some times at the switched off engine and make sure that the pedal course does not vary.
  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 some times. If the pedal is deeply pressed the first time, and at 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. Confirming to tightness of the vacuum amplifier the pedal should not change the a course in 30 seconds of its keeping.

Removal

 PERFORMANCE ORDER

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

Installation

 PERFORMANCE ORDER

  1. Establish the amplifier with a new lining.
  2. Establish on an amplifier rod bracket.
  3. Tighten nuts of fastening of the amplifier with effort of 13 Nanometers.
  4. Insert a pin in bracket and a pedal of a working brake and fix it pinом.
  5. Establish a returnable spring of a pedal of a brake.
  6. Establish on ГТЦ a new lining.
  1. Establish on a lining the special adaptation and lower a core of the adaptation till the moment of a contact with the piston.
  1. Remove the special adaptation with ГТЦ and establish on the amplifier.
  1. Measure a backlash 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 its end slightly concerned a core of the special adaptation.

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

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