Check of operation of the brake amplifier

There are two ways of performance of this survey, with a tester and without it. It is usually possible to define approximately a condition without tester use.

For carrying out this check, be convinced that in the hydraulic highway there is no air.

Survey without a tester

Air impermeability check


  1. Start the engine.
  2. Stop the engine after it will work 1-2 minutes.
  3. Press several times the brake lever with that effort, as at usual braking and pay attention to a pedal course. If the pedal the first аз leaves deeply, but its course decreases at the second and the subsequent pressing, necessary degree of air impermeability is reached.
1 — the 1st
2 — 2nd
3 — 3rd
  1. If the course of a pedal does not change, necessary degree of air impermeability, is not reached.

In case of malfunction, examine vacuum lines of consolidation and replace any faulty elements.

  1. After that repeat all procedure of check.
1 — the 1st, the 2nd, the 3rd

Work check


  1. When the engine is stopped, several times press the brake lever with the same effort and be convinced that the course of a pedal does not change.
  2. Start the engine, having pressed the brake lever. If the pedal course increases a little, the brake works normally. If the course of a pedal does not change, it testifies to malfunction.

Air impermeability check under loading


  1. When the engine works, press the brake lever. Then stop the engine, holding the brake lever the pressed.
H — hold
  1. Hold the brake lever pressed during 30 seconds. If the height of a pedal does not change, a brake condition the good. But if the pedal rises, a brake condition the bad.

H — hold
T — 30 seconds
