What tool is use to screw the cylinder back in on the back disc brakse of a Ford 500?

Answer 1

You can purchase this tool from most auto parts supplier, or tool stores that carry automotive tools. On this particular car however, BEWARE that the right/rear caliper has to be turned COUNTERCLOCKWISE while compressing the caliper piston, to put it back into its fully compressed position. On the left/rear it's the same as any other rear disc brake setup incorporating the parking brake into it, where you turn the caliper piston clockwise, and compress. One last note, is to make sure the notches on the caliper piston are at the 12 and 6 o'clock positions, relative to the caliper. Those notches are where the lock tabs on the brake pads rest. Attempting to carry this procedure out in any other method than what I've described will result in the calipers needing to be replaced. Hope this helps.

Ah yes, the old hair pulling rear disc brake caliper piston.

Most calipers are different and this is why they have a "cube" shaped tool that fits most applications. I bought mine years ago at some place like AutoZone or PepBoys. Each side of the cube has a different shaped protrusion to fits in that little "hole" on the face of the piston. You push down while turning the cube that uses a standard 3/8" ratchet wrench.

Even with "the cube" it is a painful task so allow yourself some time and a wall or two to punch out when you get frustrated.

You might get some silicone grease (small tube) to slip in-between the rubber boot and the stainless steel piston to make it easier to turn.

Good Luck!
