Changing brakes on an '06/'07ford freestar, how do we push the cylinder back in?
We bent a cast iron pipe clamp trying to push the brake cylinder back in, it didn't budge.

As it turns out, the cylinders had to be compressed AND twisted to get them back in.

you need to use a hand crank lever that can push the piston back

. Bleed all the pressure from the cylinder. Should be a "Zerk"-type fitting on the back of the cylinder or on the master cylinder.
. Be sure to bleed air from entire system when finished replacing pads.

I know how to change brakes, we tried all of that already.

I've had problems where the cylinder was so crappy from corrosion that the piston WOULDN'T go back. I had to push the piston out, then remove the caliper, then clean the cylinders with a fine abrasive on a piece of dowel.
CLEAN the cylinders scrupulously to remove any contaminating grit before you reassemble.
