frozen caliper pistons, how do I get them out??? Options

[skline]

Alrighty, I am rebuilding 4 911 m calipers, for vented rotors. On some, the piston will not push itself out with air pressure, they are stuck.... Help! I need to do this myself and I am cheap lol. Heat maybe?

BTW this is DRIFTERJAY...not scott...

No I should have tried that, I think I was too impatient....

But, I let the calipers soak, took a pair of channel locks and squeezed the pistons in to "unfreeze" them, yes there was some resistance at first, hooked up the compressor and they did not pop, they "POPED", it kinda startled me (IMG:style_emoticons/default/biggrin.gif) one piston came out first, so I put it back, propped a piece of wood in there while it was in the vise(limiting the amount of travel for the one piston), and the other poped out.

I am currently soaking the other front calipers and will duplicate this again.

Eric,
My next question is the rear calipers, I got them apart, however, Im having trouble getting the spring clip that is holding the "hat and the adjuster" out, my spring clip doesn't have the small holes like the ones that you took pictures off in your directions, they are more like a "C" on each end of the spring clip. Update: I got that part done, the hat seems to move some.

Can I push on the hat to relive pressure on that clip? Update: Yes it does.

and secondly, will the E-Brake lever come out?
