Key Features

• DFC GEOSPEC coated rear rotors with a silver-gray corrosion-resistant finish
• 5000 Advanced ceramic brake pads with post-cured friction material
• Scorched pad surface to reduce initial break-in time
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• Dry-processed rotors that are ready to install without oil removal
• Non-directional rotor finish for more even pad bed-in and smoother braking
• Hardware designed with PTFE coating, vulcanized rubber, and stainless steel

Product Details

DFC’s GEOSPEC rotor line is engineered to match OEM-style specifications for durability, stability, and consistent braking performance. The coated rotor surface helps resist rust, while the machined finish supports quieter operation and more even pad contact. The 5000 Advanced ceramic pads are formulated for stable friction performance and are assembled with shims that help reduce brake noise and vibration. This makes 4512-40155 a practical rear brake kit for Ram ProMaster 1500, Ram ProMaster 2500, and Ram ProMaster 3500 service work.

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

Common Brake Issues This Kit Addresses

• Rear brake noise, squeal, or vibration
• Rust buildup on rotor surfaces
• Uneven pad wear from fatigued hardware
• Reduced braking consistency from worn rear components
• Longer service time caused by rotors that require cleaning before installation

Installation Notes

• Fits rear axle applications only.
• 2014-2021 Ram ProMaster 2500 and 3500 listings apply only to vehicles without Heavy Duty Brakes and with solid rear rotors.
• Inspect calipers, slides, and mounting points before installation.
• Follow proper brake bedding procedures after installation for consistent pad transfer.
• Verify rotor and pad orientation against the vehicle’s rear brake configuration before assembly.
