I'll be doing a brake job soon (13" front, OEM size rear), and I need a little help . The Chilton manual(yeah, I know... don't give me a hard time ) says that when replacing the rear pads, the piston needs to be compressed and then rotated with a special FoMoCo tool. Is this really needed, or what? Also do all fronts need the Torx bit for servicing? I have a '96 Sport.
