When the air is good, the vacuum state can be maintained for a long time. I habitually brake several times before departure. If there is an abnormality, the vacuum booster that is started obtains the vacuum guide source from the intake duct of the
New Car engine and stores it in the vacuum tank. If it is found that the vacuum booster cannot work properly, it is necessary to check the vacuum booster.
When there is no fault, in order to avoid damage to the booster, do not dismantle the vacuum booster casually. If the vacuum booster is damaged, it needs to be replaced as a whole. For the braking system using a vacuum booster.
Usually, the brake pedal is stepped on several times with the force used when braking. If there is no change in each stroke, it means that the vacuum booster or vacuum tube has air leakage and needs to be repaired. When the
Fuel Car engine is not working, the brake pedal is generally stepped on several times with the force used when braking to ensure that the pedal stroke does not change, and then put it in the position of the brake pedal and start the Fuel Car engine.
At this time, the pedal height drops slightly, which means that the vacuum booster works well. Step on the brake pedal when the New Car engine is working, then turn off the New Car engine and keep it in the position of the pedal. If the pedal height remains unchanged, the sealing effect will be good.
