In Reply to: Caliper rebuild in time 4 Xmas posted by Brad on December 22, 1999 at 19:08:22:

: Was planning on driving home for Xmas, when Mon. a front caliper locked on. I suspect corrosion in caliper piston wall. Although it may not be the best repair, plan on cleaning & renewing seals in caliper, and bleed system. (cash flow not available for a new caliper) It'll be a street side repair. Question. Any suggestions for popping piston out if a supply of compressed air is not handy? Thanks in advance and best for the holidays

i did it with the big screwdriver like the other reply to your post. be careful you don't drive the screw driver thru your hand (the one holding the caliper) A vise would be good, i don't have a big enough one. all 8 pistons sitting on my bench. i cracked off a small portion of one lip (by prying) not rendered inoperable. so look out and make sure you keep prying from different points around the piston as best you can (there's a couple really obvious GOOD spots) and they come out. biggest longest flat tipped you have. you need at least 12" of lever arm.
BTW, where did you (will you) buy rebuild kits? i'm the quintessential cheapskate and i'm poised to go w/ BMP (i could share phone, address, pricing, part #'s) but i keep thinking there's got to be a cheaper solution, since it's just 4 square o-rings and the dust boots (which you don't REALLY need) so maybe we could converse on parts sourcing. Good luck!
John
