Typically, you take one of the pads that you removed, place it on the piston and use a large clamp to compress it back it. Some vehicle have pistons that screw in.
Most autoparts stores have a free loan a tool program, where you can get a tool specifically designed to push the piston back in. If the piston is ceased and won't move, then you'll likely have to replace the whole caliper. After market parts are cheap and a rebuilt caliper is about $125.
The 1995 has pistons that screw in I rented a tool from Auto Zone that made it a snap.
you want to collapse it flush with the caliper, dont pust it in to where the piston sinks, just flush will do ya'
you need to use a rear brake caliper piston turning tool... you can't use the push method... the piston have to be turned as they screw out as the pads wear. i found out the hard way.. i broke 2 c-clamps...
Poor lubrication. Excessive rpm's. Defective piston. Problem with the wrist pin, bushing or piston rod.
On the fronts, you can use a C clamp to compress the piston but the backs you have to screw the piston in, don't use the C clamp because you will screw it up, they sell the small tool that you use to screw in the piston at any auto parts store.
once you separate thecaliper from the brake pad, look at the piston, it should have two small indentations on the face. the piston screws in and out. you will need a tool to do this. this tool can be purchased at your local auto parts store. it is a cube shaped device with a square drive. insert the tool into the inserts and rottate the piston counter-clockwise until the piston bottoms out in the caliper.note- the tool you can purchase is usually made of aluminum or pot metal meaning you might get threeor four good uses out of it.
Remove engine, disassemble, replace piston, re-assemble engine and install. Good times!
It is just about the hardest most difficult part of an engine to replace. The engine has to come out. The head has to be taken off. The rod of the piston has to be disconnected from the crankshaft. the top of the cylinder has to have a ridge reamer operated on it to get the piston out.
How much does a car cost?
you bring it to a shop
Which piston? what's wrong. If it's a piston in the engine, you'll need a major rebuild. If it's a master cylinder or wheel cylinder piston, just replace the cylinder, it's not worth the trouble.
There are 8. One for each piston
