Most motorcycles have disk brakes -- lightweight yet powerful devices to stop the wheel through friction by way of brake pads. Brake pads are mounted on calipers, which are attached to motorcycle's rotor. Lubricating and cleaning the disc brake calipers regularly will help you stop more safely and effectively. "Motorcyclist Magazine" advises purchasing replacement seals for your calipers in advance, and asking your dealer how many sets you'll need for each caliper.

Skill level:
Moderately Easy


  1. 1

    Remove the calipers from the rotor with an Allen wrench and detach the brake line from the caliper. Spray the insides of the calipers thoroughly with brake cleaner. Quickly wipe down any overspray on your motorcycle with a rag to avoid stripping chrome finish or chassis parts.

  2. 2

    Detach the seals from the top of the caliper bores using a screwdriver. Remove grime from the insides of the bores with a rag and cotton swabs. Apply brake cleaner.

  3. 3

    Inspect the pistons for signs of rust and dirt. Spray the inside of the calipers and pistons with brake cleaner liberally to remove any contaminants.

  4. 4

    Reassemble the seals, using only brake fluid for lubrication. Replace the brake pads and brake line onto the caliper. Mount the caliper back onto the rotor.
