Pete, Not directly answering your question, but a couple of mechanic's troubleshooting tips. Are you you 100% positive that it is the caliper itself? Sometimes the ends of the canti bosses get a little bit of flare, and a high quality (one with tight tolerances, little play) caliper will bind. If this is the case, some plumber's tape and patience can solve the problem. Another common problem is that the sleeve in the caliper is a little too long for the boss. The boss needs to extend ever so slightly past the end of the caliper sleeve. This can be remedied by some very careful filing of the front of the sleeve. If the inner diameter of the caliper sleeve appears to be the problem, rolling some emory cloth to approximately the diameter of the boss and rotating the caliper on it will allow you to judiciously remove some material from the I.D.
Again, sorry if you've checked all of this, and simply have a defective product. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
