通用汽车刹车片4M5Z12029BC，替代DG507/DG541/9E5E-12A366-AA

If you hear a sharp metallic grinding noise when braking, the brake pedal travel is extended, or vehicle stopping distance increases significantly, it usually means the brake pads are worn to the limit or hardened with age and must be replaced immediately. Properly functioning brake pads create friction with the brake discs to convert kinetic energy into heat, providing reliable deceleration or stopping when the brake pedal is pressed. OEM number 4M5Z12029BC; substitutes DG507, DG541, 9E5E-12A366-AA; fits various four-cylinder models under the GM family, such as Chevrolet Cruze and Buick Excelle. Installation should also include checking the brake disc surface for flatness and tightening caliper bolts to the manufacturer’s torque specification to prevent uneven wear or noise.
