Functioning check, removal and installation of the vacuum amplifier of brakes

Components of assembly of the vacuum amplifier of brakes (the model since 1994 is shown to the issue - on models of 1993 of the issue instead of a lock ring on a finger of a bar of a pusher the clip is applied)

Functioning check

 PERFORMANCE ORDER

  1. Several times squeeze out a brake pedal at the switched-off engine and make sure of lack of a difference in the size of reverse motion of a pedal at each muscleman.
  2. Squeeze out a pedal and start the engine. If at the same time the pedal fails a little more, the amplifier functions normally.

Tightness check

 PERFORMANCE ORDER

  1. Start the engine, later a couple of minutes switch off it. Several times slowly squeeze out a brake pedal. If the pedal fails with each pressing less, sealing of the amplifier is normal.
  2. Squeeze out a pedal at the working engine, then muffle it without releasing a pedal. If changes in the size of reverse motion of a pedal after keeping its squeezed out within 30 seconds do not happen, sealing of the amplifier is normal.

Removal

 PERFORMANCE ORDER

  1. Disunite the electric socket of the sensor of the course of a brake pedal.
  1. On models 1993 and 1994 of of the issue disunite the electric socket of the sensor of the course of a pedal of a brake.
  1. Otboltite the main brake cylinder from the block of the vacuum amplifier of brakes (The section Removal and installation of the combined valve (regulator)) and carefully delay the cylinder forward.
  2. Disconnect a vacuum hose of the inlet pipeline from the vacuum amplifier.
  3. By means of a small lamp find back (turned to a pedal) the end of a pusher of the amplifier. This end of a pusher fastens to the top part of a pedal of a brake by means of a small finger.
  4. Remove a fixing clip (model of 1993 of the issue) or a lock ring with the flat and goffered washers (models since 1994 of the issue) and take a finger from a pusher. Disunite the electric socket of the switch of stoplights.
  5. Give four fixing nuts and remove the amplifier from a partition of a motive compartment. Nuts are under the dashboard and for simplification of performance of a task it is necessary to use a small lamp (see an illustration).
  6. Take away the amplifier from a partition so that hairpins completely left fixing openings, then take the amplifier together with arms and laying from a motive compartment.

Installation

You make installation upside-down. Tighten nuts of fastening of the amplifier with the required effort.
