1 Answers
The brake vacuum pump may be leaking air. You need to check whether it's the pipeline or the brake drum specifically. Symptoms of damage: The symptoms of a faulty brake vacuum pump include poor braking performance or no braking effect. Operating principle: During the braking process, the vacuum entering the booster pump is controlled to move the diaphragm. Through a linkage device, the push rod on the diaphragm assists the driver in stepping on and pushing the brake pedal, thereby amplifying the force applied by the driver. Specific function: The vacuum booster pump uses the vacuum generated by the engine during operation to provide some assistance to the driver when stepping on the brake, making braking feel lighter. If the vacuum booster pump is damaged, there will be no assistance, making the brake pedal feel heavier. The vacuum pump cannot be repaired and must be replaced.
