The tool is made by lisle and can be picked up at auto parts store for around 10-15$ and looks like a little cube with pin and 3/8 hole for your ratchet and needs to be pushed in as you twist

How to replace rear brakes on ford focus 2001

to replace rear pads on a focus,you need to remove the caliper assembly remove both pads you will notice that the caliper piston has a grove, that is where a special tool locates because the caliper has the hand brake incorporated in it and has a thread in the back of the piston you need the tool to put pressure and turn the piston to move the piston down into the bore of the caliper to allow for the extra thickness of the new pads then , make sure that the piston grove is in the right position because the pad locates in that grove so fit pads back into caliper make sure your slides in the caliper are moving freely so you dont get any binding of the pads refit caliper do the same on the other side but the only thing different is that the piston turns opposite ,you will see if you are turning the wrong way the piston will try to turn out of the bore and you need it to turn in .BE VERY CAREFUL when the job is complete and you are ready to test drive the vehicle you need to pump the pedal until you have a full and solid bake pedal, because you need to push out the caliper pistons before you have a solid pedal and then you will need to top up your brake fluid at the master cylinder and your ready to go regards agwbk

2006 uplander-how to push the rear brake cilinder back to change the pads ?

On those brake calipers you need to turn the piston as you push the piston in. Of course, there is a tool for doing this. Using a C-clamp or a caliper piston tool, push the piston in, then with the other brake tool, turn the piston clockwise a turn or two, and then repeat with the C-clamp. Spraying the piston and seal with WD-40 will help in turning the piston to collapse it back into the caliper.

Rear brake caliper piston on 03 mustang will not retract back into piston housing even under pressure of c clamp with bleed valve open.

Either the caliper is frozen or or you need a special tool that will allow the piston to be screwed back in at the same time pushing the piston in. If the piston is solid and has grooves in it it requires the tool. If the piston is open in the center then most likely the caliper is bad. Alternatively you can use a c clamp and something that can be used to turn the piston such channel locks but the tool works best.

Left hand side brake is sticking,i can easerly push piston back to free it off but one push of the peddle and its stuck again

Replace the left caliper. Afterwards flush through all the old brake fluid with new fluid by bleeding all of the brakes, and replace any other calipers or rear wheel cylinders which appear to be leaking or corroded.

Caliper overhaul kits are available and are cheaper, but you need to know for certain that the caliper piston and bore are undamaged: a seized caliper will always have damage to one or the other and is therefore not suitable for an overhaul kit.

2008 grand caravan rear brakes

Older vehicles with caliper parking brakes rotated their pistons in a ratchet effect.To retract those they needed to be pushed in and rotated at the same time.I cannot stand rear disc brakes.Seems they fail way too often.GM had that issue with its W body cars (1987-up),pads would wear to steel in 6 months or less. Did the face of the piston have 2 or 4 square/rectangular/round holes in it? There is a tool to hook onto a ratchet to let you turn and push the piston back in. If you banged it in, the system may not work correctly.
Go and rent the Caliper Brake Kit from Auto Zone, it make your brake job way easier. This tool compresses the piston while it rotates clockwise. So if you are going to do your own rear brake job get this tool or something similar. 
Good luck and hope this helps. Keep me posted, Recap: The cylinder does not compress on the rears, it screws back in. A special tool for rear calipers works best but a pair of needle nose pliers will do in a pinch.

Passat 2003 tdi, brake pad change..

Proper size wrenches and a large C-clamp to push piston back into the caliper is only tools for the front, but back disk brakes require special tool to TURN the piston as it is pushed back into caliper to reset emergency brake. This tool can often be borrowed from Auto parts store or purchased from Harbor Freight for about $20. Don't try to service rear disks without the tool, Calipers can be broken if not retracted properly!

Cant compress piston on rear brake calipers

Use a caliper wind back tool which rotates the piston at the same time as pushing it back. Release the bleed screw to assist the wind back. If you use a brake hose clamp on the brake hose this will reduce the need to bleed the system.

How to push back the piston in the rear brake caliper of Focus LX 2ltr 2003

There is actually a special tool for pushing the piston back, you could try and put some force on the piston but at the same time you have to turn the piston because the hand brake works of there aswell and there is some thread inside that keeps on adjusting the caliper piston as the pads waer down.
Take special care not to damage the calliper rubbers when turning the piston

DON'T FORCE THE PISTON WITH A C-CLAMP! On VW rear disc brakes you need to rotate the piston while pushing it back in otherwise you will mess up the caliper. You do need a special tool and can probably borrow one from an auto parts store. If not they can be purchased for ~$50. Look here:

There are many other place to buy this so shop around.
