Title: Re: Brakes

The shiming is done to the caliper not the pads . Look at the piston travel and see if they are all going in and out the same amount . If not correct it first . Then measure using a feeler gage set between the piston & pad backing plate . If they are not equall shim the caliper or remove some material from the caliper mounting boss to get proper alingment .   When you are doing the measurements and lets say there is a .010 difference . Place a .010 shim or feeler gage between the pistons and the pad that is off and pull the brake lever . You will see or feel the difference . Another problem with calipers that are not centered is one pad will drag causing power loss and uneven pad wear . Eric H. ----- Original Message ----- From: Sat Tara S.

Sat Tara,             Don't forget we're talking about a set of calipers that have been ADAPTED to work with those rotors. I fully agree with your statement if the calipers were designed for those rotors and fork mountings, but in this case, I think Eric is right, IMHO Dudes, Maybe I'm misunderstanding the problem. The way I understood what Eric was saying was that in situations where there is appreciable piston-to-piston difference in static clearance you should use shims between the piston and the pad to take up the slack. There are a couple of different ways to understand piston-to-piston differences. One is inside to outside, or caliper-to-caliper (inter-caliper) another is difference within pistons in a caliper (intra-caliper). I took Eric to be talking about intra-caliper differences. I still think that for intra-caliper differences, unless the caliper is cocked out of alighnment with the disk, the only way you'll get a problem is if the piston isn't doing its job correctly. If the problem is inter-caliper difference it seems to me that the shims should be relocating the caliper, not adjusting piston-to-pad distance. Am I missing something? best, Sat Tara
