What Are the Possible Causes of EPB Failure?

[McDamian]

This indicates a malfunction in the electronic parking brake system. To resolve this issue, it is necessary to visit a 4S shop to inspect the faulty component and determine the cause. About the electronic parking brake: Many vehicles are equipped with electronic parking brakes, and numerous mid-size sedans utilize this system. The structure of the electronic parking brake differs from that of the mechanical handbrake. Vehicles equipped with an electronic parking brake have parking brake motors on the two rear wheels. When the electronic parking brake button is pressed, the electronic parking brake motor clamps the brake pads, preventing the vehicle from rolling. About electronic parking brake failure: Generally, failure occurs either due to a malfunction in the electronic parking brake motor or a fault in the electronic parking brake circuit. The mechanical handbrake features a handbrake lever connected to handbrake cables. Pulling the lever engages the two rear wheels, preventing the vehicle from rolling. Over time, the handbrake cables of a mechanical handbrake may loosen, requiring periodic tightening by car owners. If the handbrake cables are loose, the vehicle may still roll even after the handbrake is engaged.
