tooley Posted April 19, 2010 Share Posted April 19, 2010 got my brakes back this weekend but unfortunatly it looks like part of the powder coating has gotten into 2 of the caliper piston barrels before i start gouging and scratching it off has anyone had this problem and do you think nitromors or something similar may shift it am gutted as apart from the above the job is awesome Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 19, 2010 Share Posted April 19, 2010 Ask the powder coaters what will dissolve it, and not the caliper bore? Coconut or soda blasting would work. Link to comment Share on other sites More sharing options...
colsoop Posted April 19, 2010 Share Posted April 19, 2010 I used to mask the bits i wanted to keep with several layers of masking tape then get the nitromoors out to soften the coating only. Then scrape off with a sharp blade(watch you don't damsage the piston barrel) Be really careful though as it easily runs and can damage surrounding sections, also make sure the nitromoors doesn't stay on the tape too long as it will go through it.

VIL Posted April 23, 2010 Share Posted April 23, 2010 Vapour blast. Takes off the powder coating and leaves the metal untouched. Not expensive either, I recently has an aluminum bike frame done and only cost me £25.00 Link to comment Share on other sites More sharing options...
