Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are built around two core components: coated cast-iron rotors and advanced friction pads. The rotors use a durable coating to help resist rust better than conventional paint or zinc finishes, while the pads are formulated for consistent braking response and reduced break-in time. Part number 4502-48101 is a practical choice for rear brake maintenance on Chevrolet Express and GMC Savana vans that need dependable stopping performance and OE-style fitment.

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

What This Brake Kit Helps Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or poor pad-to-rotor contact
• Rust buildup on exposed rotor surfaces
• Reduced stopping performance from worn friction material
• Longer service time from separate rotor and pad sourcing
