What Causes the Squeaking Noise When Releasing the Electronic Parking Brake?

[Ruiz]

The reason for the squeaking noise when releasing the electronic parking brake may be that the brake pads are severely worn and have reached the position of the wear indicator. Friction between the wear indicator and the brake disc can produce a squeaking sound. Another possibility is that new brake pads or discs have just been replaced, and there is a break-in period during which squeaking may occur. Methods for brake maintenance include: High-temperature protection to prevent corrosion of the braking system, avoid brake pads seizing due to high temperatures, and eliminate brake squeal; Cleaning oil stains, dirt, and friction dust from the brake discs, brake drums, and any other components to ensure good heat dissipation of the brake discs; Regularly replacing brake fluid; Periodically checking the thickness of the brake pads or brake shoes.
