Dynamite Friction 4512-31137 Disc Brake Kit - Front

Front Brake Kit for BMW Performance and OE Fitment

The DFC GEOSPEC Coated Rotors with 5000 Advanced Brake Pads - Low Metallic and Hardware Kit, part number 4512-31137, is a front disc brake kit built for BMW applications that require OE-style fit, stable braking, and corrosion-resistant rotor protection. It combines coated rotors, low metallic pads, and matching hardware for a complete front brake service.

Key Features

• DFC GEOSPEC coated front rotors with a silver-gray finish that resists rust better than conventional paint or zinc coatings
• 5000 Advanced low metallic brake pads with post-cured friction material for consistent pedal response
• Scorched pads to reduce initial break-in time and improve first-stop performance
• Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
• Non-directional rotor finish for smoother pad bed-in and quieter braking
• Hardware kit included for a complete front brake service
• Part number 4512-31137 for easy ordering and catalog matching

DFC Brake Kit Line Details

DFC combines coated rotors, advanced friction materials, and brake hardware in one service kit to simplify front brake replacement. The rotor design is processed dry and ready to install, while the pad formulation is developed for specific axle applications across BMW passenger vehicles and performance-oriented trims.

Detailed Description

This front brake kit is engineered for BMW 430i, 540i, 740i, 750i, 840i, M340i, M440i, M550i xDrive, X5, and X7 applications listed below. The GEOSPEC rotors use G3000/G11H18 cast iron and are machined to tight tolerances, then inspected for balance and critical dimensions. The 5000 Advanced pads are post cured and scorched to support stable friction characteristics from the first stop, while the included hardware helps restore proper caliper movement and spring tension during brake service. If you are replacing worn front brakes on a BMW 430i, BMW 540i, or BMW X5, this kit provides the rotor, pad, and hardware components needed for a complete front axle refresh.

What It Helps Fix

• Front brake noise from worn pads or fatigued hardware
• Rust buildup on exposed rotor hats and edges
• Uneven pad wear caused by corroded or weakened hardware
• Brake pulsation related to worn or out-of-spec rotors
• Reduced initial stopping response from aged friction material

Installation Notes and Fitment

Compatible With front axle applications only. Verify rotor style and brake package before ordering, since several BMW models listed here use different front brake configurations.
