This is the kit I use to retract the rear calipers. Also, I’ve never pried on the front calipers. I use a few pieces of oak wood to remove them. I tap them out from hub side.Looks super easy exc for getting the rear piston retracted. No way am I using needle nose pliars and channel locks to twist it. There is a BMW tool for that job??? Suggestions. Also how to get the glued on pads off the first time. Prying on the painted caliper also seems like a terrible idea.
