The Story
Rear Brake Kit for Heavy-Duty GM Trucks
The DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads and hardware kit is built for rear brake service on select Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD models. Part number 4512-48142 combines coated rotors, ceramic pads, and brake hardware in one service kit for a more complete rear brake repair.
Key Features
- Rear disc brake kit for select Chevrolet Silverado 3500 HD and GMC Sierra 3500 HD applications
- DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
- 5000 Advanced ceramic brake pads with post-cured friction material
- Scorched pads for reduced initial bed-in time
- Premium rubber-steel-rubber shims for improved noise and vibration control
- Hardware kit uses PTFE coating, vulcanized rubber, and stainless steel
- Rotor castings are machined to OE-style tolerances and non-directional finished
Product Details
DFC’s GEOSPEC rotor line is processed dry and ready to install, which helps reduce prep time during brake service. The rotors are made to G3000/G11H18 cast iron specifications and finished with a non-directional surface to support even pad bedding and smoother braking. The 5000 Advanced pads are formulated for stable friction performance and are assembled with premium shims to help reduce brake noise and harshness. Part number 4512-48142 is a practical choice for rear brake replacement on heavy-duty GM trucks that need a coordinated rotor, pad, and hardware service package.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Rear brake noise from worn pads or fatigued hardware
- Uneven pad wear caused by corroded or weakened hardware
- Reduced braking consistency from worn rear rotors
- Longer stopping distances due to aged friction material
- Brake vibration or harshness during everyday towing and hauling use
