PSFRED,

Thanks for the scholarly and detailed set of rebuild instructions; REALLY nice of you to take the time.

Two basic questions, one technical the other monetary:

1) TECHNICAL: Only one pad (of the four) showed disproportionately greater wear; the other three were about the same. It seems to me that if a single piston were sticking in the retracted position, it would show LESS wear than the other three. Conversely, if an errant piston were stuck in the extended position (which would indeed result in extra wear), wouldn't it be noticable when driving? What's more, in either case, wouldn't one find obvious uneven disk wear? (I've owned this vehicle since it was only 15,000 miles old, and I assure you the rotors have never been run too thin )

2) MONETARY: Phil sells rebuilt calipers for around $75--brand new ones for just twice that. Given the tools and effort involved in the rebuild you generously documented, do you think I might not be better served by simply replacing the part instead--assuming this trouble persists?

Regards!
