Dynamite Friction 4512-31249 Disc Brake Kit - Rear

Rear Brake Kit for BMW 328i

The DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware kit is built for rear brake service on the 2014-2015 BMW 328i with M Sports Package, single piston front calipers, and 330mm rear rotors. Part number 4512-31249 combines coated rotors, ceramic pads, and brake hardware in one service kit for a complete rear brake refresh.

For BMW 328i rear brake replacement, this kit is designed to deliver OE-style fitment, stable friction performance, and reduced brake noise. The DFC GEOSPEC coated rotor finish helps resist rust, while the 5000 Advanced ceramic pads are post-cured, scorched, and paired with premium rubber-steel-rubber shims for improved NVH control.

Product Details

DFC engineered this brake kit to match OEM specifications for durability, reliability, and stability. The rotors are machined to tight tolerances, inspected for critical dimensions, and finished to support even braking performance. The pads are formulated for consistent friction and assembled with shims that help reduce vibration and brake noise. This makes 4512-31249 a practical choice for a rear brake job on a BMW 328i where fitment, finish, and drivability matter.

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

Common Brake Issues It Can Address

• Brake noise from worn rear pads or fatigued hardware
• Uneven rear pad wear caused by corroded or stressed hardware
• Rotor rust buildup on exposed braking surfaces
• Reduced braking smoothness from worn or out-of-spec rear components
• Excessive caliper movement related to aged brake hardware

Installation Notes

Confirm rear fitment before installation: 2014-2015 BMW 328i, rear, with M Sports Package, single piston front calipers, and 330mm rear rotors. The rotors are processed dry and ready to install, which helps reduce prep time during service. Clean all mating surfaces, inspect caliper slides and mounting points, and follow the vehicle manufacturer’s brake service procedure for proper torque and bedding.

Quality Assurance

DFC states that each GEOSPEC rotor is inspected for critical attributes and that vented rotors are balance-corrected when needed. The rotors carry a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and scorched to support stable friction performance from the initial stop.
