What Causes the Brake Pedal to Make Abnormal Noises?
2 Answers
Introduction to the causes of abnormal noises from the brake pedal: 1. Friction between pedal components. If the internal parts of the brake pedal rust, it can cause friction issues between the components, leading to abnormal noises when the pedal rebounds. This situation is relatively simple to resolve—just remove the brake pedal, reapply lubricating oil for lubrication. 2. Intervention of the car's ABS system. When the car experiences sudden braking, the ABS system intervenes in the braking system to prevent wheel lock-up. At this time, the brake pedal may feel like it's pushing back, and the "clicking" sound is quite normal. Precautions to take when braking: 1. Brake slowly and avoid sudden stops whenever possible. 2. Anticipate deceleration, maintain a safe distance from the car in front, as tailgating can easily lead to rear-end collisions. 3. Properly use the "pump braking" technique to prevent wheel lock-up and loss of vehicle control.
I've encountered the issue of squeaky brake pedals several times while driving. The main cause is usually severely worn brake pads, which produce a harsh friction noise when pressed. For example, once after the rainy season, my car's brake discs rusted, causing uneven surfaces and frequent abnormal noises. Another common issue is lack of lubrication in the pedal joints—applying specialized oil can solve this. Additionally, checking the brake fluid is crucial; if the level is low or there are air bubbles, the pedal may feel spongy and produce noise. Debris stuck in the gaps is also a frequent problem, which can be resolved by cleaning it out. However, minor issues shouldn't be ignored. I've seen a friend delay repairs, leading to brake failure and nearly causing an accident. I recommend regular maintenance checks and replacing worn parts early—safety first. Also, paying attention to road conditions and avoiding sudden braking can extend component lifespan. When getting repairs, choose reputable shops for peace of mind.
