What Causes the Sound When Braking in Reverse Gear for Automatic Transmission?
1 Answers
The sound that occurs when pressing the brake pedal while reversing is likely coming from the brake disc and pads. This issue is usually caused by the hardened surface layer of the brake pads. Additionally, it could be due to the chamfering effect that develops after prolonged use of the brake pads. The solution is to have the brake pads resurfaced at a 4S repair shop. Handbrake Operating Principle: The handbrake, technically referred to as an auxiliary brake, operates differently from the main braking system. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness and increase the handbrake's travel distance. The handbrake system also includes a return spring. When the handbrake is engaged, the spring stretches; when released, it returns to its original length. Over time, this spring can also deform with extended use. The Necessity of Proper Brake Usage: The handbrake is a frequently used system. Proper and correct usage ensures smoother operation in the future, extends its adjustment intervals, and reduces maintenance and replacement costs.
