Cleaning caliper pistons
Am rebuilding the calipers on the Dayton dual piston brakes. I have the pistons out and need to clean the scorched on brown stuff off. Any suggestions?

I've rebuilt calipers and I recommend it.
The Piston in a Caliper does pretty much what the BORE does in a Wheel Cylinder. In a Caliper, the only surfaces that really matter are the O-Ring Groove and the Retaining Groove for the Dust Seal. Naturally you want any gunk and loose rust out of the caliper's "cavity" but if the O-Ring fits well (given the Piston is OK) it should work without leaking. And if the Dust Seal is retained properly, it should stay clean.
