Nice vid. The EPB actuator works a rod that pushes on the inside rear of the caliper piston. Its touch contact, so pushes only against the piston. When it retracts, it just pulls away from the back of the piston face, it doesn’t actually put any ‘pull’ force on the piston to retract it.
I think you will find your electronic service tool requires you to press the button to turn the parking brake off before attempting to do it with the tool, That's the way it works on my iCarSoft tool (took me a while to figure out that what was causing the failed error message). Hope that helps...
Many thanks great video, although i wish i came across this video before i tried to replace myself. Didn't remove the connector before removing the calibre and pads and then the EPB self activated and pushed out the piston fully ! Doh ! Managed to get the piston re-engage and pushed back just enough to get new pads back and brakes seem to working properly but now a warning notification keeps coming up "Park Brake Requires Calibration Apply Foot and Park Brake" any recommendation on how to fix/reset ?
Did you not have a wear sensor on the brake brakes , mines come up with brakes worn on the dash , looked at the brakes and still some meat left on them but for a couple of weeks it’s still says brake pads worn how to get rid of this message
It's a nice video, detailed explanation, but I noticed something, there is a lot of rust under these models, is this normal? Or is it too humid where you live?😮
In the car press and hold down the accelerator (keep it down) Whilst holding the parking brake switch up (in the engage position) switch the ignition on, off then on. This will put the parking bake actuator back into normal operating position. To retract the parking brake actuator, do the same as above only hold the parking brake switch in the off position
