Is the Sound Like Pumping Air When Braking Normal?

[SanElle]

The sound like pumping air when braking is a normal phenomenon. Causes: The brake system uses a vacuum-assisted braking system, and the operation of the booster pump will produce intake and exhaust sounds. The brake pedal, as the name suggests, is the pedal that limits power, i.e., the pedal of the foot brake (service brake), used for deceleration and stopping. Methods to Extend Brake Pad Life: Emergency braking causes significant damage to brake pads. When driving normally, pay attention to braking slowly or using intermittent braking (pumping the brakes), which results in less wear on the brake pads. Develop good habits to reduce braking frequency while driving. For example, use engine braking to lower the speed before applying the brakes for further deceleration or stopping. Downshifting can also help in slowing down the vehicle. If the vehicle shows signs of pulling to one side, promptly perform a wheel alignment to prevent tire damage and uneven wear on the brake pads on one side of the vehicle.
