Hey Neil, Hi Rebuilding brake calipers is frowned upon, though obviously it *is* done. You are seeing why it's not recommended to rebuild calipers, at least that's the rap I hear around all the roadracing guys I hang out with, Personally, I don't know that much about ATE but I'm infinitly acquainted with Brembos. I certainly wouldn't (didn't) bet my life on anyone (myself included) being meticulous enough with the fussy job of re-building brake calipers. The tolerances have to be very precise, the parts have to be kept really clean, the specs. closely followed. The actual condition of everything inside the castings? I'd want to have them ex-rayed or ultra sounded or something to rule out structural flaws, too...not something I (and many others) would choose to leave to a stranger. I bet they don't give much of a crap down there in Matamoros or Tijuana, or where ever the re-build factory is.. How much are you saving by not replacing your calipers (if indeed the old ones are bad) with new rather than rebuilt? Again, dunno that much about ATE..but your brakes..kinda important.
