2 Answers
Electronic parking brake replacement of brake pads method is: 1. Use a jack to lift the front part of the car; 2. Use tools to remove the tire; 3. Unscrew the caliper screws, remove the damaged brake pads and replace them. The electronic parking brake is a technology that achieves parking braking through electronic control. The working principle of the electronic parking brake is: to achieve parking by clamping friction between the brake shoes and the brake drum or between the friction pads and the brake disc, with the control method replaced by electronic buttons and motors instead of the original manual operation and mechanical linkage. The full name of this system is the Electronically Controlled Mechanical Parking Brake System.
I just replaced the brake pads for my electronic parking brake myself, and it was quite a challenge. First, make sure the car is turned off and parked on a level surface, with the regular handbrake engaged or wheels chocked to prevent rolling. The electronic parking brake uses a motor to drive the brake caliper, so it can't be disassembled as easily as a traditional handbrake. You must use an OBD diagnostic tool to enter maintenance mode and release the parking brake system—without the tool, you'll have to visit a repair shop for help. Next, remove the wheel, loosen the caliper bolts with a wrench, and carefully take out the old brake pads, avoiding dust getting into your eyes. After installing the new pads, press the caliper piston back in. If the electronic parking brake piston doesn't reset, you might need a special tool or manual adjustment by turning it. Before reinstalling the wheel, always exit maintenance mode and test the brake response. The whole process takes about one to two hours and requires a full set of tools. Beginners shouldn't force it, as it may damage the system or compromise safety. I spent an afternoon tinkering in the garage and finally got it done, but I still recommend seeking a professional technician for a more reliable job.
