Fig. 6.12. Check of the course of a pedal of a brake at the switched-off engine


Press a brake pedal several times with the switched-off engine and be convinced that the stock of the course of a pedal does not change (fig. 6.12).
Press a pedal of a brake and start the engine. If the pedal of a brake smoothly goes down, the vacuum amplifier is efficient.

Fig. 6.13. Check of the course of a pedal of a brake at the working engine


Start the engine and stop after one – two minutes of work. Slowly press a brake pedal several times (fig. 6.13).
If the pedal falls below by the first pressing, than at the second and third – the vacuum amplifier is tight.
Press a brake pedal at the working engine and stop it at the pressed pedal. If the distance between a floor and the pressed pedal within thirty seconds does not change – the vacuum amplifier is tight.
