Read a lot of posts lately about caliper rebuilding/cleaning. Don't forget to get the groove that the square cut seal rides inPERFECTLY clean. I've found a dental pick (one of those nasty scary tools the dentist uses to clean between your teeth) perfect for cleaning the edges of the groove. You just need to talk your dentist into giving you one.

That is a very good point, I've never seen a tool mentioned before, though I guess there must be something available.

Bend a nail and grind the bent end to fit the groove. Use an offset screwdriver with a piece of rag. Wipe out with a rag dipped in brake cleaner.

Check your Army/Navy Surplus stores. For whatever reason the ones around here have buckets of old dental picks. If anybody really needs one I'm sure I can send some out...

You want to be VERY CAREFUL if using any sharp tools to clean that brake caliper piston groove. Any nicks or sharp scratches will cause future "O" ring leakage & "O" ring degradation, that groove is the sealing surface of the "O" ring to the piston.

I used a brass wire wheel for my Dremel. I used a variable speed device and slowed the tool way down. It worked like a champ, no scoring and very speedy to use.

As I stated, I used a variable speed attachment to bring the speed of the tool down to an acceptable limit. I did not observe any etching or abrasion to the groove and I've run about 5000 miles since the rebuild with no leaks around the caliper area. You can't be ham handed no matter what youuse. The calipers, as you know, are cast aluminum or something close. I just brushed the seals grooves gently with the wheel. I think that there's more of a chance of damage using a stainless steel pick that using a soft wheel.
