Tackle a complete front brake refresh in one box with the DYNAMIC FRICTION brake kit (P/N 4212-48129, also written 421248129), a front disc brake kit that bundles DFC's GEOSPEC-coated rotors, heavy-duty (HD) brake pads, and the mounting hardware together. It drops in as a direct-fit replacement for the front axle of a wide range of GM work-duty trucks and vans, including the 2003-2020 Chevrolet Express 3500, 2001-2010 Chevrolet Silverado 2500 HD, 2001-2007 Chevrolet Silverado 3500, 2003-2020 GMC Savana 3500, and 2001-2010 GMC Sierra 2500 HD — see the Buyer's Guide tab for the full list of covered applications.
Worn rotors and pads can show up as squealing, grinding, pulsation through the pedal, or longer stopping distances. If your front brakes are due, this kit replaces the rotors, pads, and hardware in a single purchase. Replace both sides together for even, balanced braking.
Is this a front or rear brake kit?
It's a front disc brake kit — the GEOSPEC-coated rotors, HD pads, and hardware all serve the front axle of the listed GM trucks and vans.
