I have upgraded Guide RE's brakes to Code RSC, but I have problems adjusting the caliper to prevent any rotor rub - it seems that clearance between pads and rotor is a bit to small. I have 220mm SRAM rotor (which is 2mm thick) which does not show any warp. Already pushed pistons all the way in using bleeding block and after mounting the caliper back there was about 1mm of clearence on each side of the rotor, but then I pumped the lever the pads moved in and again stayed quite close to the rotor. Is there any way to adjust this clearance of the pads to the rotor on these brakes? I already dropped a few drops of DOT fluid from the lever side and I think it helped a bit, but I would still want a bit more pads clearance to prevent any rub, possible?
