What Causes the Abnormal Noise When Braking in Reverse?

[McSophia]

The reasons for abnormal noise when braking in reverse: 1. When braking in reverse, the brake caliper lifts and hits the upper bracket, causing abnormal noise, which is a normal phenomenon; 2. After prolonged use, the brake pads develop a chamfered edge, which can be resolved by grinding at a 4S shop; 3. During emergency braking, the ABS frequently activates, producing a sound similar to a spring releasing, and the brake pedal may rebound with abnormal noise—this is a normal operation of the ABS system. When the vehicle moves from the warning zone into the danger zone, the radar system automatically activates the braking mechanism to control the vehicle's reverse motion. The principle involves adding a servo with braking functionality to the standard reverse radar. When the vehicle enters the danger zone from the warning zone, the controller sends a signal to the braking servo, which immediately initiates automatic control to stop the vehicle from reversing, ensuring safe reversing.
