Why is there a noise under the gear when shifting to P and stepping on the brake?

[DiJosie]

There is a reason for the noise when shifting to P and stepping on the brake. Normal factors: After parking, the gear lock switch is equipped with an electromagnetic switch on the brake pedal to prevent misoperation and accidental gear shifting. The lock is only released when the brake is pressed, allowing gear shifting. Therefore, the noise is produced when the electromagnetic switch engages upon pressing the brake. Brake pad factors: There might be deviations in the steel back length of the brake pads, possibly due to excessive brake pad clearance. It is necessary to inspect the rear brake system to ensure all bolts are properly installed and tightened. Solutions: For normal factors, shifting from P to any gear requires stepping on the brake, as this is a safety feature to ensure driving safety. Otherwise, the car may immediately generate forward or backward driving force, and the handbrake alone might not be sufficient to stabilize the car, potentially causing danger. Alternatively, check if the brake system is functioning properly.
