Organic Kevlar pads are OEM type replacement brake pads for 1970s and earlier models. Organic Kevlar pads are the perfect choice for polished or chromed rotors and Billet Steel Rotors. All compounds of Drag Specialties brake pads are asbestos, nickel, and lead free. NOTE: If you are using aftermarket billet steel rotors it is recommended you use our Organic-Kevlar brake pads to avoid damage to them. Sintered pads are not recommended for billet steel rotors as the pad material is too aggressive for those rotors.
