In addition to our brake pad compounds we have the carbon kevlar materials in three different formulas of brake shoes. Porterfield brake shoe compounds exhibit quick warm-up and consistent friction over prolonged use. Higher than average friction levels mean you have the best stopping power throughout a wide temperature range without material glazing or fade. All our brake shoe compounds have been rigorously tested on nearly every form of racing vehicles and vintage race car. Our Porterfield racing shoes are high temperature bonded then arced to drum specifications and finally copper riveted to the brake core to ensure the strongest possible material adhesion. Porterfield racing shoes will withstand the most rigorous racing conditions with consistent and powerful stopping performance.
