Dynamic Friction 4514-31069 Disc Brake Kit - Front and Rear

Brake Kit Overview

This DFC brake kit combines coated rotors, ceramic pads, and hardware for a complete brake service on select BMW applications. It is built for BMW 335i, BMW 340i, BMW 435i, BMW 440i, and ActiveHybrid 3 models with M Sport brake configurations.

Part number 4514-31069 is a fitment-based brake service kit for front and rear axle service, with application notes covering standard rotor designs and aluminum hat rotor setups where listed.

Key Features

• DFC GEOSPEC coated rotors resist rust and arrive dry for installation.
• Non-directional rotor finish supports even pad bed-in and smoother braking.
• 5000 Advanced ceramic pads are post-cured and scorched for stable friction.
• Brake hardware uses PTFE coating, vulcanized rubber, and stainless steel.
• OE-spec machining and inspection support consistent fit and finish.

Detailed Product Information

The DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Ceramic and Hardware line is a complete brake service solution that pairs corrosion-resistant rotors with ceramic friction material and replacement hardware. The coated rotor surface is processed dry and shipped dry, which reduces prep time during installation and helps protect the rotor from rust before service. The rotor casting is machined to tight tolerances and finished to OE specifications for durability, reliability, and stability.

The 5000 Advanced pad formulation is built for stable friction performance, with post-curing and scorching used to reduce initial break-in requirements. Premium rubber-steel-rubber shims are used to improve noise, vibration, and harshness control. Part number 4514-31069 is listed for BMW 335i, BMW 340i, BMW 435i, BMW 440i, and ActiveHybrid 3 applications with M Sport brakes across the covered model years.

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

What It Helps Address

• Brake noise from worn pads or fatigued hardware.
• Uneven braking feel caused by rotor wear or inconsistent friction surfaces.
• Rust buildup on exposed rotor surfaces.
• Excessive caliper movement linked to aged brake hardware.
• Longer brake service time caused by unprepared rotor surfaces.

Installation Notes and Tips

Use this kit on the exact BMW fitments listed for front and rear brake service. Confirm rotor style notes before ordering, especially for standard rotor and aluminum hat rotor applications. Clean mating surfaces thoroughly and follow proper brake bedding procedures after installation to help the pads and rotors seat evenly.

Quality Assurance

DFC states that the rotors are manufactured to OE specifications and inspected for critical dimensions and balance. The rotors carry a 12-month warranty against defects in material and workmanship.
