Why is there a strange noise when stepping on the brake and turning the steering wheel while reversing?

[Joan]

This phenomenon occurs when the brake caliper hits the caliper bracket during reversing. The specific reasons are as follows: 1. Under the influence of gravity, the brake caliper moves downward, and the brake caliper is floatingly connected to the bracket. 2. When driving forward and stepping on the brake, there is no play gap at the lower connection part with the brake bracket, so no noise will occur. 3. When reversing and stepping on the brake, the brake caliper moves upward and hits the upper bracket, causing a strange 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 a 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, brake parts, and an operating device. Some brakes are also equipped with an automatic adjustment device for the gap between brake parts. 4. To reduce braking torque and structural size, brakes are usually installed on the high-speed shaft of the equipment, but for large equipment with higher safety requirements (such as mine hoists, elevators, etc.), they should be installed on the low-speed shaft close to the working part of the equipment.
