Key Features

• DFC GEOSPEC coated rear rotors with a silver-gray corrosion-resistant finish
• Rotors are processed dry and ready to install
• G3000/G11H18 cast iron construction for OE-style durability and stability
• Non-directional rotor finish for more even pad bed-in and smoother braking
• 5000 Advanced Brake Pads are post-cured and scorched for consistent friction performance
• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
• Part number 4502-31236 for rear brake service on select BMW models

Product Details

The DFC GEOSPEC rotor and 5000 Advanced pad combination is engineered for rear brake service where OE-style fit, finish, and braking consistency matter. The coated rotors help resist rust better than conventional painted or zinc-coated surfaces, while the pad compound is formulated for stable friction and reduced break-in effort. This makes the kit a practical choice for BMW 120i, BMW 320i, BMW 228i, BMW 328i, and BMW 428i rear brake maintenance.

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

What It Helps Solve

• Rear brake noise during stopping
• Rotor rust and surface corrosion
• Uneven or inconsistent brake feel
• Extended pad bed-in after brake service
• Brake vibration caused by worn rear components
