Product Details

DFC engineered this brake kit to match OE specifications for durability, reliability, and stability. The coated rotors are machined to tight tolerances, inspected for critical dimensions, and finished to promote even pad contact. The 5000 Advanced ceramic pads are formulated for stable friction performance and are assembled with shims that help reduce brake noise, vibration, and harshness. Part number 4512-48112 is a practical rear brake solution for drivers servicing a Chevrolet Silverado 1500 HD, GMC Sierra 2500, or Hummer H2 rear brake system.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Brake Kit Helps Address

• Rear brake noise from worn pads or fatigued hardware
• Uneven pad wear caused by corroded or stressed hardware
