Hey Raleigh, I'm going to be doing a complete brake caliper rebuild too. Front, back and both master cylinders. I'm sure I'll be using the site that Miller gave out, cause I lost my dealer discount that I my buddy used to get. That site is within pennies of my old discount of 25%.
I'll post my shopping list in this thread, maybe it'll help you figure out what you want to do with yours. All the internals of the brake calipers are original on my bike. I rebuilt my Clutch master and slave cylinders, that's what clued me to the fact that rubber bits in my bike are due for changing.
Listen, about upgrading, I run the Galfers too. So do some others on this forum. I had slight visual runnout on one of my stock rotors, so a new set was in order. The Galfers have performed perfectly for me. Granted, I'm easier on my stuff than any track person, but for the street. I don't doubt mine for a second. They're better than what I had before for sure. (cause they're straight) On the other hand, gts455 hated his. And it sounds like LDH has heard his share of feedback too. But I think SubSailor runs them.
Check out my recent thread on Galfers. Why do Galfer discs suck?
One last thing; I've read as an opinion from some who would know, that for factory brakes, the RC51's are about as good as any that come from any factory. If I'm wrong here, please chime in. But I've read that a couple times now. ???
