Performance Friction manufactures the VERY BEST BRAKE PADS YOU CAN BUY! PERIOD. . Compound is CARBON based, NOT METALLIC based...so no overheating of rotors - which then need replacing - I have a 1971 Chevy C20 with over 1 Million miles...rotors last at Least 300,000 miles with these Pads....my father bought Pickup new in 1970.......brake service people says it's "your driving style. .." NO SIR! ...JUST WRONG PARTS....DO YOUR RESEARCH. ..Performance Friction are THE BEST!....
