FMSI number 7973A-D1334. Made in the United States. This listing is for one pad set; for even, balanced braking, replace the pads on both sides of the axle together as a matched set. If worn rear pads are the cause of noise or reduced braking, this set replaces them—diagnose the cause before ordering. Signs the pads may need replacing include squealing, grinding, longer stopping distances, or thin remaining friction material.
