A c-clamp will work just fine. If it takes a lot of pressure to retract the piston the caliper may need replacement or rebuilding.
Yes, you need to remove the caliper first, then use the old brake pad and a C clamp to push down the piston of the caliper.
Dual piston caliper, 85 ft lbs. Single piston caliper, 37 ft lbs.
You have to use a special tool to turn the piston in clockwise. The tool has two pins which match the two recess holes on the piston. Since the caliper is also the emergency brake you cannot just c clamp the piston back into the caliper bore. you should be able to rent the tool at your local autozone or autoparts store.
Turn the piston clockwise and it scews itself in...
Use a large C- clamp to depress the piston enough to remove the caliper.
First make sure the parking brake is OFF, then remove the caliper and use a C-clamp to SLOWLY depress the piston until it is flush with the caliper surface. Second, on some vehicles however you may need a special tool to turn the piston to depress it. Third, consult a repair manual as the procedure may be different still.
The rear piston has to be turned in, it won't just push in, they make a tool at the parts store that makes it easier, if you have tried turning it in and it won't go you will have to replace the caliper as it's bad.
There not like the front calipers where you put a c-clamp on the piston and squeeze them in, on the rear calipers you have to get a special tool from the parts store and as you push inward you have to turn them in.
the caliper needs a special tool. the piston does not push straight in. the spring needs to be released at the rear of the caliper. then using the special tool the piston twists back in to place
if it is the caliper at the rear u need the special tool to turn the piston clockwise to push in and counterclockwise to pull out
Remove wheels Remove caliper mounting bolts Slide caliper off rotor Rotor should slide off hub a special tool (not expensive available at Sears or auto parts) is required to fully depress piston into caliper body (piston is threaded) After piston is fully seated in caliper body Replace inner and out brake pads and re-install caliper PUMP BRAKE PEDAL TO SET PADS AGAINST ROTOR PRIOR TO MOVING VEHICLE
You will need special brake caliper tool such as a C-clamp to push back the piston on the caliper of a 2002 Mitsubishi Lancer.
