i have an gen 1 -03 the brake pads rattle in the caliper when i hit a bump i just replaced the pads and lines before i went to arkansas for mng when i took them i noticed it doen't have the shim in it that shouls have been in there. but the brakes work great hardly have much pull on the lever before the start to grab. i usaually pretty good with brakes systems on bike. but kinda scratching my head on this one any ideas
