Check without the measuring device Stage 1
| PERFORMANCE ORDER |
| 1. At the switched-off engine several times press a brake pedal. | | 2. Holding a pedal pressed, start up the engine. | | 3. If the pedal of a brake moves down at once after engine start-up, it testifies to normal operation of the vacuum amplifier of brakes. | |
Stage 2
| PERFORMANCE ORDER |
| 1. Start up the engine. | | 2. In 1–2 minutes stop the engine. | | 3. Press a brake pedal 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 operation of the vacuum amplifier of brakes. | | 5. Otherwise, check the unilateral vacuum valve or a vacuum hose on absence of damages and check reliability of their fastenings. | |
Stage 3
| PERFORMANCE ORDER |
| 1. Start up the engine. | | 2. Press a brake pedal with usual effort. | | 3. Stop the engine. | | 4. Slowly press a pedal of a brake and hold it pressed during 30 pages. |
| 5. If the height of a pedal does not change, the vacuum amplifier of brakes works normally. |
6. Otherwise, check the unilateral vacuum valve or a vacuum hose on absence of damages and check reliability of their fastenings.
If malfunction still is not eliminated, execute more detailed survey, using a manometer and the vacuum gage. | |
Check by means of the measuring device Connect a manometer, a measuring instrument of vacuum and a pressure force measuring instrument on a pedal, as is shown in drawing. After air removal from a manometer carry out the test according to 3 points given below.
Prevention
Use sensors available on sale and a pressure force measuring instrument on a pedal.
а) Check of reduction of vacuum Not loaded condition
| PERFORMANCE ORDER |
| 1. Start up the engine. | | 2. Switch off the engine when indications of a measuring instrument of vacuum become equal 500 mm Hg. |
| 3. Watch indications of a measuring instrument of vacuum during 15 pages. If they are in limits of 475-500 mm Hg, the system means is serviceable. | |
The loaded condition
| PERFORMANCE ORDER |
| 1. Start up the engine. | | 2. Press a brake pedal with effort of 196 N. | | 3. Holding a pedal pressed, switch off the engine when indications of a measuring instrument of vacuum will make 500 mm Hg. | | 4. Watch indications of a measuring instrument of vacuum during 15 pages. If indications of a measuring instrument of vacuum are in limits of 475-500 mm Hg, the system is serviceable. | |
b) Check of hydraulic pressure
| PERFORMANCE ORDER |
| 1. If at the switched-off engine (vacuum of 0 mm Hg) pressure of liquid corresponds to the requirements provided below, the system is serviceable.
| Force of pressing a pedal | Pressure of liquid | | 196 N | 1,177 kPas | |
| 2. Start up the engine. Press a brake pedal when indications of a measuring instrument of vacuum will make 500 mm Hg. If pressure of liquid corresponds to the requirements provided below, the system is serviceable.
| Force of pressing a pedal | Pressure of liquid | | 196 N | 1,177 kPas | |
