Why does the brake squeak when reversing?
2 Answers
During the reversing process, the brake caliper hits the brake caliper bracket when the brake is applied, and the specific reasons are as follows: 1. Under the effect of gravity, the brake caliper moves downward, and the brake caliper is floatingly connected to the bracket. 2. When driving forward and applying the brake, there is no play gap at the connection part with the lower part of the brake bracket, so no sound will occur. 3. When reversing and applying the brake, the brake caliper moves upward and hits the upper bracket, causing abnormal noise, which is a normal phenomenon. Here is some extended information about brakes: 1. A brake is a device that has the function of decelerating, stopping, or maintaining the stopped state of moving parts (or moving machinery). 2. A brake is a mechanical part that stops or decelerates moving parts in machinery, commonly known as a brake or a brake shoe. 3. A brake is mainly composed of a bracket, braking parts, and an operating device. Some brakes are also equipped with an automatic adjustment device for the gap between braking parts.
A few days ago, I also encountered the issue of squeaking brakes when reversing, which gave me quite a scare! Upon closer inspection, it might be due to the brake pads being nearly worn out or rust on the brake disc surface, as the load differs when reversing, making friction more prone to noise. I used a flashlight to check the pad thickness and found only a little left. If I had delayed replacing them any longer, it could have affected the entire braking system, which would have been very dangerous. Now, with new pads installed, everything is quiet again. Everyone should pay more attention to the dashboard warning lights and regularly inspect brake components. Safe driving should never be taken lightly, especially after rainy or humid conditions when noises are more likely to occur. Early detection and timely action are key.
