Service function guideElectronic Parking Brake Service Mode

This guide covers the complete process of placing an electronic parking brake (EPB) system into service mode so that rear brake pads and rotors can be replaced without damaging the caliper piston or motor assembly. It is written for working mechanics and experienced DIYers who already understand hydraulic brake systems and are comfortable using a scan tool with bidirectional controls. You will learn how the EPB works, how to prepare the vehicle, how to retract and re-apply the caliper pistons correctly, how to verify the job, and how to troubleshoot when the system refuses to cooperate. By the end, you will be able to perform a safe, repeatable EPB pad service on most common vehicle platforms and know when to stop and consult factory service information.
