There is a tool with a couple of expanding ears and a threaded shaft through the middle that allows you to push the piston while turning it in clockwise at the same time. Some auto parts stores will loan the tool to you, or rent it. You may be able to do it without the tool if you can find a way to accomplish the same thing. There are a couple of slots in the face of the piston. If you can use needle nose pliers to twist while you use the use a pair of big waterpump pliers to compress, you may be able to do it.

Hope this helps,

New brake rear discs and pads on a ford mondeo 03 but can not get the caliper pisten to go back enough to fit pads

Loosen the brake fluid reservoir cap to allow pressure to escape. Use a large C clamp connecting it to the front of the piston and back of the housing. Turn the screw on the clamp to compress the brake piston then release the clamp. The piston will remain compressed allowing you the fit the housing over the new brake pads.

How do i get the rear caliper compressed on a G6

For the rear you need to turn the piston as you crank with the C clamp. It's a lot easier with the right tool. Any good parts store has the tool. The tool to use is a universal brake caliper tool, I picked mine up from Pep boys for $10 bucks. The tool fits on a socket wrench and you turn it clockwise to depress the piston into position.
If everything is apart and you don't have an extra car, just used a pair of sturdy needle nose pliers to get int the groves and twist, no pressure needed.
Tork it down just enough to get the caliper back on. Once it is all bolted back up you will pull many many times on your e-brake handle to tighten the piston back up against the new pad.
Good luck, but try to use the tool.

Rear brake piston compression problem? How do I compress the rear piston into the caliper to allow new brake pads to be installed?

As far as I know, most front disc brake setups have pistons that are pressed back into the cylinders using a C-clamp or something similar.

However, not all rear disc systems are like this. There are some that require that the rear pistons be screwed back into the cylinder bores. These pinstons usually have some kind of indentations on the front where special tools fit and help move them back into the cylinder.

Your Hyundai may have this kind of setup.

Changing the rear brake pads on 91 mu

Chalk the front wheels, car is on jackstands i hope, release the handbrake, use the old pad with a c- clamp to compress the pistion on the caliper, install new pads. may have to take the cap off the master cylinder, if none of this works, open the bleeder valve, and compress the piston, rebleed the caliper.
