    Disc Brake Replacement, need special tool?

    I have heard that a special tool is needed to push in the calipler pistons when replacing disc brakes. Is this true for both front & rear? Can't I just use a large c-clamp like I've done on all my other disc brake cars? 2000 Grand Marquis w/o antilock

    the problem is that they use dual piston calipers, so if you use a c-clamp you wont compress both calipers evenly. you would have to use two clamps at the same time. also you want to crack the bleeder before you compress the pistons, otherwise you can damage the ABS pump

      Tools?

      Thanks,

      Another few questions:

      Rear Calipers: I looks like there is more to remove than just the calipers, are the caliplers part of the parking/drum assembly?

      It looks like the bolts that hold the front calipers are two in number and are regular hex head, not allen head.

      Is this true?

        No, the calipers are not part of the parking brake assembly. Those are little drum type shoes inside the rotor, behind the axle flange.

        There are just 2 bolts to remove on the rear caliper and it comes off. They should be allen key type I believe. The ones on my car at any rate.

          What I always did when I had my 2000 was use the old brake pad and put it on there and use the c clamp and compress them that way. Worked great.

            x2 That's the way to do it......

            I use that method on every brake job, even on single piston calipers to avoid damaging the piston with too much pressure on one point.

                X4, that method works even on E450 calipers, which are about twice the size of the Panther ones.

                  I thought everyone knew the old pad and C clamp trick. The fun ones are non-floating calipers with opposing dual pistons. Can't use that trick on those.

                    Yep, for them there's another simple trick - pull caliper, pull rotor, put caliper back on (loosely), take two BIG flat screwdrivers or two small crowbars, jam one on each side between pads, and PULL then PUSH then PULL again. Works well even with SRT-10 monsters of calipers with 4 pistons.

                            Last Question, another special tool?

                            I was at NAPA, the guys there said I might need this $10 tool the you attach to a ratchet with an extention and twist while pushing the piston back into the caliper, otherwise you wil blow out the piston seal first time you use the brakes. The guy said you could NOT use a c-clamp when using this tool that grabs the top of the piston so you can twist it.

                            Anyone know about this?

                            Thanks!

                              you dont need that stupid tool.....i use a big screwdriver to push the piston in while it's still bolted up to the rotor......pull the caliper, replace the pads, go do the other side, put it all together, pump the brakes up and drive it
