I recently added a front break to my fixie and the noise it makes has gone from bad to terrible within a matter of days. I have a Velocity deep v Wheelset. This particular wheelset is powder coated, and I have a strong feeling that this is the reason my breaking sounds like a hell scream. Does anybody have a remedy for this or should I get some earplugs?
dirt pinned between the brake pad and braking surface cause brake noise. keep your braking surface clean (the fact that you're rubbing away the powdercoat isn't helping that situation) and clean it with simple green. you might want to sand your brake pads just a little as well, but that's just an extra precaution.
file the pads down a bit, toe them in, rub the braking surface with sandpaper to make sure its clean and smooth.
any goo or lubricant is a big no-no.
if you really want to go for it, mask and knife and edge into the PC, then use a sanding block to take off the coating and essentially machine the rim yourself. Or find a machine shop with a big lathe...
