Dynamite Friction 4502-48108 Disc Brake Kit - Rear

Rear Brake Kit for Trailblazer, Envoy, and More

The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is a rear disc brake service kit built for OE-style replacement and consistent stopping performance. Part number 4502-48108 combines coated rotors and advanced friction pads for select Chevrolet, GMC, Saab, Isuzu, Buick, and Oldsmobile applications.

Compatible with rear brake service on vehicles such as the Chevrolet Trailblazer, GMC Envoy, and Saab 9-7x, this kit is designed for drivers replacing worn rear rotors and pads on a range of 2002-2009 platforms.

Key Features

• Part number 4502-48108 rear disc brake kit
• DFC GEOSPEC coated rotors with silver-gray corrosion-resistant finish
• Rotors ship dry and ready to install
• Non-directional rotor finish for even pad bed-in and smoother braking
• G3000/G11H18 cast iron rotor specification
• DFC 5000 Advanced Brake Pads with post-cured friction material
• Scorched pads to reduce initial break-in time
• Premium rubber-steel-rubber shims for improved NVH control

Product Details

DFC GEOSPEC rotors are machined to tight tolerances, finished with a non-directional surface, and inspected for balance and critical dimensions to meet OE specifications. The coating is intended to resist rust better than conventional paint or zinc finishes, while remaining safe for the friction material during normal braking. The 5000 Advanced Brake Pads are formulated for stable friction performance and consistent pedal feel across a wide range of driving conditions.

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

What This Kit Helps Address

• Rear brake noise from worn pads or uneven rotor surfaces
• Brake pulsation caused by rotor wear or thickness variation
• Reduced stopping performance from aged friction material
• Rust buildup on exposed rotor surfaces
• Longer service time from rotors that require extra prep before installation
