Anti-rattle insert for Coleman or Wilwood brake caliper

This modification may work to reduce the pad rattle you hear on bumps or initial brake application:

  • Remove the pads and the caliper from the steering knuckle, retaining any shims between the caliper and bridge..
  • Pull the bottom edge of the stainless steel thrust plate away from the aluminum casting and insert a 1/4" bolt half-way up, between the plate and the casting.
  • Push the bottom edge out so that you end up with a bend in the middle of the plate.
  • Do the same for the other thrust plate.
  • Reinstall the caliper and pads with original shims.
