Dynamic Friction 4504-31107 Disc Brake Kit - Front and Rear

Brake Kit for BMW M Sport Applications

This Dynamic Friction disc brake kit combines DFC GEOSPEC coated rotors with 5000 Advanced brake pads for BMW applications that use M Sport brakes. It is built for drivers who want OE-style braking performance with corrosion protection and pad materials tuned for stable friction.

• DFC GEOSPEC rotors feature a silver-gray coating that resists rust better than conventional paint or zinc finishes.
• Rotors are processed dry and ready to install, with no oil coating to remove before service.
• Non-directional rotor finishing supports quicker pad bed-in and smoother, quieter stops.
• 5000 Advanced brake pads are post-cured and scorched to promote consistent friction from the first stop.
• Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness.

Detailed Product Overview

Part number 4504-31107 is a complete brake service kit for select BMW 340i, 335i, 435i, 440i, and ActiveHybrid 3 models with M Sport brakes. Fitment includes 2013-2020 BMW 3 Series and 4 Series applications listed in the fitment table, including front and rear coverage for vehicles with optional full cast rotors or original design aluminum hat rotors. The DFC GEOSPEC rotor coating is engineered to protect the rotor surface during storage and service, while the cast iron construction is machined to OE-level tolerances for durability and stability. The 5000 Advanced pads are formulated for controlled friction and improved initial response, making this kit a practical choice for BMW brake service.

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

What This Brake Kit Helps Address

• Brake rotor corrosion on vehicles exposed to moisture and road salt
• Uneven pad bedding after rotor replacement
• Brake noise, vibration, and harshness during normal stopping
• Reduced initial braking response after service
• Service delays caused by cleaning oil-coated rotors before installation

Installation Notes and Tips

Verify rotor style and brake package details against the vehicle’s brake system before ordering. This kit is listed for front and rear applications on the supported BMW models, including M Sport brake configurations with the notes shown in the fitment table. Follow standard brake service procedures, inspect related wear items, and bed in the pads according to the friction material manufacturer’s recommendations.

Quality Assurance

DFC states that each rotor is inspected to confirm critical dimensions and OE-spec compliance, and the rotors carry a 12-month warranty against defects in material and workmanship.
