Product Details

The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads line is built around matched brake components for rear axle service. The coated rotors are machined to tight tolerances, finished for consistent pad contact, and inspected to meet OE specifications. The 5000 Advanced pads are post-cured for stable friction behavior, scorched to reduce initial break-in, and assembled with shims to help reduce noise, vibration, and harshness. This makes 4502-52023 a practical choice for drivers looking to restore rear braking performance on a Buick LeSabre rear brake kit application or a Pontiac Bonneville rear brake kit application.

What This Kit Helps Address

• Rear brake pulsation from worn or uneven rotors
• Reduced stopping performance from aged pads
• Brake noise caused by worn friction material
• Rust buildup on exposed rotor surfaces
• Longer service time during brake replacement
