Abstract
A semi-metallic lining is attached to one side of a disc brake shoe. A ceramic heat barrier is attached to the other side of the shoe. A rubber compound is attached to the heat barrier on the side opposite the shoe and a second shoe is attached to the rubber compound. An additional rubber compound is on the opposite side of the second shoe. The caliper piston rests on the additional rubber compound. The rubber compounds have high energy absorbing, vibration damping characteristics. They are heat resistant, ozone resistant, brake fluid resistant, oil resistant, must have low displacement and must be firm. Shoe mounting pins fit loosely through holes in the first shoe and heat barrier and tightly through holes in the second shoe. The loose fit through the first shoe eliminates a possible noise path from the lining through the first shoe and the pins into the caliper. The pins retain the entire shoe and lining assembly within the caliper.
