What is the solution for brake booster failure?
2 Answers
Brake booster failure solution is: it is necessary to check whether there is any air leakage in the vacuum pump or pipelines, and also to check whether the vacuum pressure sensor is malfunctioning. If there is a malfunction, it needs to be repaired in time to avoid accidents. The reasons for brake booster failure include: 1. Loose connection or air leakage in the brake booster vacuum hose; 2. Poor quality of brake shoes or lining blocks; 3. Bent or broken brake shoes; 4. Blocked or obstructed brake pipelines. The brake booster is a widely used brake assist device from light-duty vehicles to medium-duty vehicles, which can be roughly divided into vacuum assist, hydraulic assist, and pneumatic assist.
Speaking of brake booster failure, I've encountered this situation several times. The solution is to first identify the cause. It could be a vacuum pump leak, a cracked hose, or a blocked vacuum line, all of which make the brake pedal hard to press. Emergency measures? Immediately press the pedal hard several times, downshift to slow down if the speed is high, and pull over as soon as possible. For a long-term solution, have a professional mechanic inspect the vacuum system, such as using a pressure test to find leaks and replacing damaged hoses or pump components. Safety first—I always recommend not trying to fix it yourself and going straight to a reputable repair shop. Prevention is also important; have the booster system checked during maintenance every six months to avoid regrets later. Remember, if the car isn't handling well, turn it off and don't risk driving.
