Product Description

Part number 4202-48021 is a rear disc brake kit for heavy-duty Chevrolet and GMC trucks and SUVs. It is listed across 2011-2019 Chevrolet Silverado 2500 HD, Silverado 3500 HD, and Suburban 3500 HD rear applications, plus 2011-2019 GMC Sierra 2500 HD and Sierra 3500 HD rear applications. Because fitment varies by model year and parking brake hardware, confirm the exact rear configuration before ordering.

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

Common Brake Service Issues

• Rear brake wear on Silverado HD and Sierra HD trucks
• Brake noise during stopping or low-speed braking
• Reduced braking performance from worn rear components
• Service needs tied to parking brake hardware configuration
• Uneven rear brake operation on heavy-duty applications

Installation Notes

Verify year, make, model, rear position, and parking brake hardware style before installation. This kit is listed for rear use only, and some applications require matching the coil or clip style spring parking brake shoe hardware noted in the fitment data. Compare the existing brake setup on the vehicle to the fitment notes for an accurate match.

Quality Assurance

Dynamite Friction part 4202-48021 is cataloged for specific heavy-duty GM rear brake applications and should be matched to the vehicle’s exact configuration for proper service.
