How to compress rear caliper 1G.

[norcalTSI]

Just Finished putting on new rotors and brake pads on the front.
In order for me to get the pads over the rotor on the REAR I need a way to
compress piston. Tried a C clamp and pring. A hammer did not work well
either... I loosend up the bleeder valve but that did not seem to do much.

I would really like any assisatance as I type working on car right now.

Do not try to compress them! They need to be screwed in. Take a pair of needlense pliers, fit the tips into the V shape grooves on the piston, and turn. RTM

Is there any particular way its suppost to turn?
It seems like its really hard to turn when it does
move. can you lube it up at all?

It'll be kinda stiff, hopefully you didn't use that C- clamp too hard. Turn the pistons clockwise, it's reverse threaded. Turn them slowly and make sure the pliers don't slip and rip the rubber boot. Good Luck, it should be easy from here.

Umm, #@%#@%#@%#@%... When I replaced my rotors I used a C clamp to compress them, in the Chiltons manually it did not mention this.

The screw-in pistons are only in a 1G. 2G's have compress fit pistons. Relax.

As far as which direction, righty-tighty, lefty loosey. In other words, turn it to the right to compress the piston.

They make a special tool for the piston, you can pick it up at autozone for about 5 bucks

But the c clamps i already have (and are easy to use), what would be an advantage of a piston compressor?

hehe that happened to me too. I stared dumbfouned till it occured to me what the notches on the piston were for.
