The Story
Rear Brake Kit for GM W-Body Applications
The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is a rear disc brake service kit built for select Chevrolet, Buick, and Pontiac applications. Part number 4502-45043 combines coated rotors and matched friction material for a direct-fit rear brake service on vehicles such as the Chevrolet Impala, Buick Allure, Buick LaCrosse, and Chevrolet Monte Carlo.
Key Features
- Rear disc brake kit with rotors and pads in one package
- DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
- Dry-processed rotors ready to install without oil removal
- G3000/G11H18 cast iron rotor construction for OE-style durability
- Non-directional rotor finish for smoother pad bed-in and quieter braking
- 5000 Advanced pads are post-cured and scorched for stable friction performance
- Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
- Part number 4502-45043 for rear brake service applications
Product Details
DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a matched rear brake solution for drivers servicing GM passenger cars with rear disc brakes. The coated rotors are machined to tight tolerances, inspected for balance, and finished to support even pad contact. The brake pads are formulated for consistent friction, with post-curing and scorching steps that reduce initial break-in effort and help deliver stopping response from the first stop. This kit is a practical choice for rear brake replacement on the 2006-2010 Chevrolet Impala, 2008-2009 Buick Allure, 2008-2009 Buick LaCrosse, and 2006-2007 Chevrolet Monte Carlo. Part number 4502-45043 is also a useful reference when searching for a rear brake kit for these applications.
Common Reasons for Replacement
- Rear brake noise, squeal, or vibration
- Rotor rust, scoring, or uneven wear
- Reduced braking response from worn pads
- Pulsation or inconsistent pedal feel during braking
- Service needs on a Chevrolet Impala rear brake kit, Buick LaCrosse rear brake kit, or Chevrolet Monte Carlo rear brake kit
Installation Notes and Tips
Compatible With rear brake service on the following vehicles:
- Fits 2006-2010 Chevrolet Impala, Rear
- Fits 2008-2009 Buick Allure, Rear
- Fits 2008-2009 Buick LaCrosse, Rear
- Fits 2006-2007 Chevrolet Monte Carlo, Rear
Before installation, confirm rear axle fitment and compare the existing rotor and pad dimensions to the vehicle’s brake specifications. The rotors are shipped dry and ready to install, which helps reduce prep time during service. Follow standard brake bedding procedures after installation to promote even pad transfer and stable braking performance.
Quality Assurance
DFC states that each rotor is inspected for critical dimensions and balance, with vented rotors electronically corrected when needed. The rotors carry a 12-month warranty against defects in material and workmanship. The 5000 Advanced pads are post-cured, scorched, and assembled with premium shims to support consistent friction and NVH control.
