What you need: dedicated shop towels are a good idea because aerosol brake cleaner will eat additives and plastics in cloth or parer-type napkins and could cause more trouble. Eye protection is a good idea too when using chemicals. We show you the tools necessary to remove Magura brake pads. You'll need a slightly different kit to remove other types of pads. Finally. we used 100-grit abrasive because it gets the job done quickly. If your rotors use a spider, then make a sanding block from a paint stirring stick or similar, or carefully work the rotor with the edge of the rubber block.
