What Causes the Abnormal Noise When Braking Hard?
2 Answers
The reasons for abnormal noise when braking hard are as follows: 1. Normal activation of ABS: The working process of ABS is actually a cyclic process of locking-releasing-locking-releasing, keeping the vehicle in a state of critical locking with intermittent rolling. When hard braking triggers the ABS, abnormal noise occurs, which is a normal phenomenon. In this case, simply press the brake pedal firmly to the end. 2. Rust on brake pads/discs: After parking for a long time, especially in humid weather or after rain, some rust or dirt may appear on the brake discs or pads. This can usually be resolved by driving for a while longer, or you can apply butter or special lubricating oil to the connection between the brake pads and calipers.
I've been driving for twenty years and have encountered the issue of strange noises when slamming on the brakes several times. Usually, it's because the brake pads are severely worn down, and when they reach the metal part, they make a squeaking sound, which is quite harsh on the ears. It could also be due to rust on the brake discs or small stones getting stuck, causing noise from friction during hard braking. Once, I had to brake hard on the highway, and the sound was terrifying. At the repair shop, they found the brake pads were almost completely worn out. The mechanic said if I didn't replace them soon, it could damage the brake discs, leading to costly repairs. I recommend regular checks on the braking system—I go every six months, and it's not expensive but gives peace of mind. Ignoring these noises can affect braking distance, and on rainy, slippery roads, it could easily lead to an accident. Remember, safety first—don't take minor issues lightly.
