13.2. Check of the vacuum amplifier of brakes with use of devices
THE GENERAL DATA

After installation of the vacuum amplifier of brakes execute following actions:

      – Add a brake liquid and remove from it air;
      – Check up all connections of hydraulic system of brakes on absence of leaks;
      – Check up and, if necessary, adjust work of a pedal of a brake;
      – Check up working capacity of brake system.

Step 1

PERFORMANCE ORDER
1. At the switched off engine some times press a brake pedal.
2. With the pressed pedal of a brake start up the engine.
3. If the brake pedal moves downwards at once after engine start-up, it testifies to normal work of the vacuum amplifier of brakes.

Step 2

PERFORMANCE ORDER
1. Start up the engine.
2. In 1–2 minutes stop the engine.
3. Press a pedal of a brake with usual effort.
4. If the first course of a pedal – a long and second course, is shorter than the first course, it testifies to normal work of the vacuum amplifier of brakes.
5. Otherwise check up the unilateral vacuum valve or a vacuum hose on absence of damages and check up reliability of their fastenings.

Step 3

PERFORMANCE ORDER
1. Start up the engine.
2. Press a pedal of a brake with usual effort.
3. Stop the engine.
4. Slowly press a pedal of a brake and keep its pressed during 30 with.
5. If the pedal height does not change, the vacuum amplifier of brakes works normally.
6. Otherwise check up the unilateral vacuum valve or a vacuum hose on absence of damages and check up reliability of their fastenings.

If malfunction still is not eliminated, execute more detailed survey, using a manometre and the vacuum gauge.

CHECK OF THE VACUUM AMPLIFIER OF BRAKES WITH USE OF DEVICES


The prevention

For carrying out of tests use the accessible vacuum gauge and the device for measurement of effort of a brake applied on a pedal.


Connect the vacuum gauge And and the device for effort measurement In, a brake applied on a pedal. After air removal conduct the tests resulted more low.

Check of deduction of vacuum

PERFORMANCE ORDER
1. Start up the engine.
2. Switch off the engine when the vacuum gauge will show depression 66,7 кПа (500 мм.рт.ст.).
3. Observe of indications of the vacuum gauge during 15 with. If the vacuum gauge shows depression 63,3–66,7 кПа (475–500 мм.рт.ст.), the vacuum amplifier means works normally.

Vacuum check under loading

PERFORMANCE ORDER
1. Start up the engine.
2. Press a pedal of a brake with effort 196 Н (20 kg).
3. At the pressed pedal of a brake switch off the engine when the vacuum gauge will show depression 66,7 кПа (500 мм.рт.ст.).
4. Observe of indications of the vacuum gauge during 15 with. If the vacuum gauge shows depression 63,3–66,7 кПа (475–500 мм.рт.ст.), the vacuum amplifier means works normally.

Check of hydraulic pressure

PERFORMANCE ORDER
1. If at the switched off engine (depression 0 кПа) hydraulic pressure is in demanded limits, means, the vacuum amplifier works normally.

2. Start up the engine. When depression will reach 66,7 кПа (500 мм.рт.ст.), press a pedal of a brake and check up hydraulic pressure. If hydraulic pressure is in demanded limits, means, the vacuum amplifier works normally.
