Dynamite Friction 4512-48122 Disc Brake Kit - Rear
Rear Brake Kit for Trailblazer, Envoy, and More
The Dynamite Friction DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware kit is a rear disc brake service kit built for OE-style replacement on select GM and Saab SUVs and trucks. Part number 4512-48122 combines coated rotors, ceramic pads, and brake hardware for a complete rear brake refresh.
Key Features
- Rear disc brake kit with coated rotors, ceramic pads, and hardware
- GEOSPEC coated rotors with a silver-gray finish that resists rust better than conventional paint or zinc coatings
- Rotors are processed dry and ready to install
- Non-directional rotor finish supports even pad bed-in and smoother braking
- 5000 Advanced pads are post-cured and scorched for stable friction and reduced break-in time
- Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
- Hardware uses PTFE coating, vulcanized rubber, and stainless steel construction
- Part number 4512-48122
Product Details
DFC GEOSPEC coated rotors are machined to tight tolerances and built to match OEM specifications for durability, reliability, and stability. The coating is designed to be worn away by the brake pads during normal use, without added prep before installation. The 5000 Advanced ceramic pads are formulated for consistent friction performance, while the included hardware kit is engineered to restore proper spring tension and caliper movement on worn brake assemblies. This kit is a direct-fit rear brake solution for 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy, 2005-2009 Saab 9-7x, 2007-2008 Isuzu Ascender, 2003 Isuzu Ascender, 2004-2007 Buick Rainier, 2003-2006 Chevrolet SSR, 2002-2006 Chevrolet Trailblazer EXT, 2002-2006 GMC Envoy XL, 2004-2006 Isuzu Ascender, 2004-2005 GMC Envoy XUV, 2003-2005 GMC Jimmy, and 2002-2004 Oldsmobile Bravada. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Brake Issues It Can Address
- Rear brake noise from worn pads or fatigued hardware
- Rust buildup on exposed rotor surfaces
- Uneven braking feel caused by worn rotor finish
- Excessive caliper movement from aged hardware
- Premature or uneven pad wear
Installation Notes
Before installation, verify rear axle fitment against the vehicle listing and inspect calipers, slides, and brake fluid condition. The rotors are shipped dry and do not require cleaning of oil residue before installation. Proper pad bedding after installation helps establish even contact and stable braking performance.
Quality Assurance
Each rotor is inspected for critical dimensions and balance, with vented rotors electronically mill-balanced when required. DFC states that the rotors meet OE specifications and includes a 12-month warranty against defects in material and workmanship.
