Refresh the rear brakes on your heavy-duty pickup with the Dynamic Friction brake kit 4212-48021, a direct-fit rear package for the 2011-2019 Chevrolet Silverado 3500 HD and the 2011-2019 GMC Sierra 3500 HD. It bundles a GEOSPEC-coated rotor, heavy-duty (HD) brake pads, and the mounting hardware under one part number, so you can service worn rear rotors and pads together in a single order.
When the rear rotors are worn below spec or the pads are down to their wear indicators, replacing the rotor, pads, and hardware together helps restore consistent rear braking. Signs the rear brakes may need service include squealing or grinding, pulsation felt through the pedal, or reduced rear braking. If a worn rear rotor and pad are the cause, this kit replaces them. For even, balanced braking, service both rear corners together as a matched set. See the Buyer's Guide tab to confirm the engine and options for your truck.

Should I replace both rear sides at once?
