    Rear Brake Issues

    Hey Guys. I'm replacing the rear pads and rotors on my 1998 Deville Concours and have an issue with getting the piston to collapse. I know that the piston screws back in, but it won't turn back in far enough to get the caliper to fit over the new pads. On the front a "C" clamp worked but on the rear it won't budge. Any thoughts?

    The rears don't 'squeeze' in, they screw in. Turn them in clockwise & make sure the detents in the pistons line up with the 'nubs' on the back of the pads! I personally use a pair of needle nose vice grips for this.

    you need the brake cube -

    Make sure that the 2 V grooves in the piston face are at 12:00 & 6:00 to accept the nipple on the back of the pads.

    Re: Rear Brake Issues

    Thanks guys, I found the "cube", $13 after tax! I tried the vice grip thing and it was so difficult to turn that I thought there was a step I was missing. I screwed around with this for about three hours (I live in the Cal Foothills and it's a half hour round trip to O'Rielly's) it then took me five minutes after I bought the cube!

    Opening the bleeder valve on the back side makes it a lot easier to compress the rear pistons, even with the cube.
