Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a matched rear brake service kit for Ram ProMaster vans that use vented rear rotors and heavy duty brakes. The rotors are cast to OE-style G3000/G11H18 specifications, machined to tight tolerances, finished with a non-directional surface, and inspected for balance and critical dimensions. The coated rotor surface helps resist rust, while the pad formulation is post-cured and scorched to support stable friction performance from the first stop. This makes part number 4502-40157 a practical choice for fleet and commercial rear brake maintenance on Ram ProMaster 2500 and Ram ProMaster 3500 models.

Common Reasons for Replacement

• Rear brake pulsation or vibration during stopping
• Rust buildup on rear rotors
• Reduced braking performance from worn pads
• Brake noise caused by uneven pad and rotor wear
• Service interval replacement on high-use cargo vans

Installation Notes

Compatible With rear axle service only. Verify that the vehicle has vented rear rotors with heavy duty brakes before ordering. The rotors are shipped dry and ready to install, which reduces prep time during brake service. For best results, follow proper brake cleaning, torque, and bedding procedures after installation. Part number 4502-40157 is listed for 2014-2021 Ram ProMaster 2500 and 2014-2021 Ram ProMaster 3500 rear applications.

Quality Assurance

DFC states that the rotors are 100% inspected for critical dimensions and balance, and the brake pads are post-cured and scorched for consistent friction behavior. The rotors include a 12-month warranty against defects in material and workmanship.
