The front brake caliper should retract with minimal effort with the aid of a c-clamp and an old brake pad. If it takes alot of pressure to make it retract I would replace the caliper. The rear brake caliper is a different story because it houses the e-brake also. The brake caliper piston must be rotated clockwise as you apply pressure to retract it. This requires a special tool that you can purchase from your local auto parts store. This tool is not expensive, it should be less than $20.
on the top or back of the caliper
Sticky/stuck caliper slides, sticky/stuck caliper piston, collapsed brake hose, pinched brake line,
If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body
Could be, a frozen/sticky brake caliper, an internally collapsed brake hose, a pinched brake line,
Remove wheels Re-install 2 lug nuts to hold rotor in place Remove 2 caliper mounting bolts Slide caliper off rotor Remove outer brake pad Use inner brake pad and "C" clamp to fully retract piston into caliper body Replace inner and outer brake pads Re-install caliper REMEMBER TO PUMP BRAKE PEDAL TO SET PADS AGAINST ROTOR PRIOR TO MOVING VEHICLE
Take off Front 2 wheels behind the caliper you will see 2 bolts take off the caliper .. you need a special tool compress the caliper snap the new pads in lube them up and bolt back on the caliper ... easy as pie
Remove wheels Re-install 2 lug nuts to hold rotor in place Loosen 2 caliper mounting bolts Remove l caliper mounting bolt to allow caliper to swing giving access to pads Remove front pad Use "C" clamp and rear pad to retract piston into caliper Remove and replace rear pad Replace front pad Swing caliper back into place and secure PUMP BRAKE PEDAL TO RESET PADS AGAINST ROTORS
Squeze the caliper piston in with a pry bar or c- clamp and reomve the 3/8 Allen bolts, asembly is easy also
On my 90 it is typically like brakes. On/near the tranny, find the cylinder mechanism, there should be a 10mm bleeder like you would see on a brake caliper. pump pump release repeat
Top of the brake pedal.
On the brake pedal arm.
I don't know exactly how to do it on that particular car without looking at it, but in general disc brakes are all pretty much the same. Just remove the two bolts holding the calipar to steering nuckle, its probably an Alan in that car. take the caliper off, it may be tight. Use a C-clamp and one of the old pads and compress the cylinder of the caliper all the way back. It should be tight, but not really tight. If you have a lot of trouble getting it to compress, then the caliper is no good. lube all the slides for the bolts, I think there are 2 little cylinders that go around the two main bolts. clean them and lube them before putting the caliper back on. replace the brake pads and put the caliper back on and put the bolts back and tighten. When you compress the cylinder in the caliper, brake fluid may start coming out of the master cylinder. Don't worry, your just pushing all the fluid back up, and if there is too much in there, it comes out the top of the master cylinder, but this doesn't hurt anything.
