BMW Brake Paste is a high-quality ceramic paste that protects brake components against corrosion and wear and thus extends their service life. Brake pad paste makes the individual parts of the brake run smoothly and thus reduces noise when braking. Unlike copper paste, brake paste is non-conductive and stays in place longer.
 
Apply a thin layer of BMW Brake Pad Paste to the brake pad contact points on the cleaned brake caliper as well as to the rear pad plates. BMW recommends using two packs of brake pad paste per axle.
 
When buying a brake kit for front and rear brakes, ideally you should order 4 parts of brake paste at once.
