If the discs and pad surfaces are worn unevenly they can be
machined flat and parallel again. A fixture should be made to
mount the disc on its mounting flange, and both sides should be
machined at the same setting. Failure to do this may result in
thick / thin which will cause pedal “pulsing” and vibration. For
H13.5 discs only brown antioxidant paint is available from
AP Racing (CP2872-145) and should be “touched-up” as required.
Do not attempt to degrease the material with any solvents. If a Carbon disc is contaminated with oil or other please contact AP Racing for advice
