Oliver,
About a mohth ago I had the same problem with my TR4 calipers. I tried to
"blow" air via the brake line input but too much air leaked out to get the
piston to pop out. The thread size is 5/16 24 NF i believe.
Anyway I thought since it is a std thread, maybe if I removed the tip of the
air gun to see it the threads on the air gun were the same as the caliper and
they were, so I screwed in the airgun to the caliper and applied 120 lbs of
pressure and the pistons popped out with a loud and forcefull pop. I had
wrapped the pistons in a rag to prevent any damage and parts flying out at
high speeds.
Before I tried this I had soaked the areas around the pistons in used brake
fluif for over 2 weeks just to loosen things up.
Good Luck.
