Changing rear disc brakes on a 1997 mercury cougar?carefully, take a flat peice of wood, and a big C Clamp, and a brew. place the wood across the face of the calipers piston. put the C clamp on, and gently turn it, til it has pressed that piston all the way in. when you have sucessfully done that, every thing will be flush.
Take a gulp of brew, to celebrate the fact, that you can now, put on the new pads, and reinstall the caliper to the vehicle.
Bleeders are tricky. If you bust one off, you got mucho troublesChanging rear disc brakes on a 1997 mercury cougar?
look at the piston if there is a slot or four grooves around it you will have to turn the piston in either direction to retract that is providing the emergency cable is attachedto the caliper. if there is no cable just a small piston you can use a caliper tool to push piston backChanging rear disc brakes on a 1997 mercury cougar?
You need a special tool to screw the rear brake piston in.....I learned that the hard way. I put the car back together and took it to Ford.
FYI, the front pistons do not need to be screwed back it. A clamp will work for the fronts.Changing rear disc brakes on a 1997 mercury cougar?
Dodge man is right, those caliper pistons screw in. If you use the pliers be very careful not to damage the piston or the boot. A better idea is to run to your local parts store and buy the correct tool to do the job. It looks like a little square box that has little studs sticking out of it on all four sides. the center is open so a 3/8%26quot; extension will lock into place and you can use a ratchet to screw the piston back in.Changing rear disc brakes on a 1997 mercury cougar?
Those have to be screwed back in. That's part of the parking brake system. You could do it the right way and pay money for a specialty tool from Ford, or you can do it the cheap way and just use a big pair of Channellock pliers.Changing rear disc brakes on a 1997 mercury cougar?
I've run into this problem a few times. Go to your local ford dealer and measure the thickness of one pad including the backing plate that's bonded to it. You'll need vernier calipers or a 1-2 micrometer to do this accurately. After measuring the Ford pad measure your replacement pads. I' betting the replacements are much thicker than the originals. You may have to shop around for the correct thickness. 2 Be sure you've forced the caliper piston back in the caliper with a c-clamp. A long beam adjustable carpenter clamp works perfectly from Sears. The piston does not retract by itself unless you perform this %26amp; it was not necessary to have backed out the bleeder screw.
