Abstract

See full text

A method for reducing green roughness of a braking system and a method of manufacturing a brake system includes coating at least one of the components of the brake system with a boundary layer material. The method is applicable to either the pad of a disc brake system or the brake drum lining and/or the brake shoe of a brake drum system. The coating is either a binder, a filler, a boundary layer lubricant or a mixture thereof. The coating hereof is either graphite, molybdenum disulfide and/or a divalent fluoride, either organic or inorganic. Likewise, a thermoset paint such as an alkyd resin, phenolic resin, epoxy resin or the like can be used for the coating material. The coating eliminates uneven transfer of friction material during the brake wear-in period which creates brake torque vibration which, in turn, increases vehicle sensitivity and brake roughness.
