got an air compressor at work i could borrow - anyone tried this avid caliper surgery?

I've done this many times in the workshop but I just used a track pump and that was plenty to pop out the piston, as long as you cover all other air escape points of course. Very easy to do and will sort your problem nicely. Use a little bit of a nice silicone lube on the seals / piston edges when re-assembling as grease can introduce air into your brake fluid :-)

Give me a shout if you need any pointers but it really is very straight forward.
