If you find that your disc brake is catching or rubbing against your brake caliper we recommend the following steps:


  • Lifting up the rear of the bike and spinning the wheel, listening out for the rub.
  • Once the location of the rub has been found, move the wheel back and forth to confirm it's at that specific orientation.
  • Using either a torch or a piece of paper, look for light in between both sides of the brake pads. If one side doesn't show any light, you know that side is causing the rub and you can manipulate the caliper to ensure light can be seen on both sides.
  • To manipulate the caliper, slightly loosen both of the bolts; just enough to where the caliper can move, but not hang freely.
  • Move the caliper into a position in which all rubbing is eliminated.
  • Re-tighten both bolts according to manufacturers specification.
  • Check the disc for rubbing again, as tightening the caliper can cause it to shift.
