How to Replace Brake Pads for Electric Parking Brake?
2 Answers
Step-by-step guide for replacing electronic parking brake pads: 1. First, connect the electronic parking brake diagnostic tool, then enter the procedure for replacing the parking brake to retract the motor. 2. After installing the new parking brake pads, perform initialization. 3. Test drive the vehicle to ensure it can remain stationary on a 30-degree slope, marking the completion of the replacement process. Here's an introduction to electronic parking brakes: 1. The structure of an electronic parking brake is fundamentally no different from a conventional handbrake. Simply put, it replaces the traditional handbrake lever with an integrated operation switch, adding a small control module and an actuator motor. 2. The electronic parking brake is a new device that uses electronic control to achieve parking braking. Installed on the rear wheel brake calipers, the electronic parking brake system includes motor components controlled by a dedicated computer.
I recently replaced the electric parking brake (EPB) brake pads on my car by myself. The process was quite challenging, but I'd like to share it. First, ensure the car is parked on level ground and turned off, then use a hydraulic jack to remove the wheel—this is the basic step. Before removing the caliper, the EPB system must be properly handled; otherwise, electronic components could be easily damaged. I used an OBD diagnostic tool to connect to the car's computer and retract the piston—this is crucial, as forcing it without the tool could damage the motor or ECU. After removing the old brake pads, clean the caliper contact surfaces before installing the new pads, being careful not to let oil contaminate the friction material. Reinstall the caliper bolts and secure the wheel back in place. Start the car to test if the parking brake releases properly and check the brake feel. The entire process took about two hours, and you'll need tools like wrenches, a diagnostic tool, and gloves. While DIY can save money, it's not recommended for beginners due to the high risk of damaging electronic circuits—safety always comes first. If you don't have all the necessary tools, it's better to visit a repair shop for peace of mind.
