I don't follow. Every time I drive my car I release the parking brake. On the cars with electronic brakes, you use a button rather than a lever. I'd do it the same way to service the brakes.
- giobox 1y agoA lot of electronic parking brakes do have a service mode. For most modern Fords, there is a procedure, as one example of many: > https://www.brakeandfrontend.com/quick-answer-electronic-parking-brake-deactivation-procedures-ford-vehicles/ https://www.brakeandfrontend.com/quick-answer-electronic-par... You typically need the piston fully retracted to replace pads, which very rarely happens just by disengaging the park brake. If you are old enough to have changed a manual handbrake pad, you normally had to screw the piston back in before you could fit the thicker new pad with a "caliper rewind tool" even if the handbrake was off, the electronic parking brake service mode essentially does this for you, or unblocks the piston permitting a rewind tool to work. > https://www.thedrive.com/guides-and-gear/how-to-use-a-brake-caliper-wind-back-tool https://www.thedrive.com/guides-and-gear/how-to-use-a-brake-... FWIW, I've never found an electronic parking brake I couldn't rewind myself after a few minutes on google.
- rconti 1y agoHuh. Interesting. I've never replaced the parking brake mechanism or (separate) pads myself, though I've done a handful of brake jobs. On the cars I've worked on, the hand brake did not actuate the primary caliper so retracting the piston wasn't an issue.
