Inspection on automobile
1. Check the vacuum booster
(a) Check the gas sealed performance.
(1) Start the engine, and extinguish after one or two minutes,
then step and release brake pedal slowly several times.
Hint: if the first step is lowest, second and third step
rise gradually, and this shows the gas sealed per-
formance of booster is normal.
(2) Step down brake pedal when engine is running, then
extinguish the engine.
Hint: if the distance from pedal to floor does not
change in 30 seconds, this shows gas seal perfor-
mance of booster is normal.
(b) Working inspection.
(1) When engine is at parking state, step brake pedal sev-
eral times to check brake pedal.
The height from floor should not change.
(2) Step down brake pedal, then start the engine.
Hint: if pedal drops a little, this shows working is
normal.
2. Check vacuum check valve
(a) Check vacuum check valve.
(1) Remove pipe clamp, and disassemble vacuum pipe.
(2) Disassemble vacuum check valve.
