I am in the process of changing my rear brake caliper and have adapted a R 1150 single sided caliper to fit the existing k100 FD. The only problem I have is the brake rotor just rubs on the top of the gap in the caliper. I would like to reduce the diam of the rotor by 5mm to allow clearance. Does anybody for see any dramas in doing this. To fill in the gaps the rear wheel is now a BMW hub laced to a 15 inch rim and the conventional caliper will not clear the spokes. Would I need any special tooling to trim the rotor down being stainless.
