What It Helps Address

• Worn brake pads that reduce stopping performance
• Rotor scoring, vibration, or uneven braking feel
• Brake noise caused by aged pad and rotor surfaces
• Service intervals that call for a full front and rear brake refresh
• Fitment-specific replacement needs on BMW 550i GT and 750-series models

Installation Notes

Verify rotor design notes before ordering, especially on BMW 550i GT and 750-series vehicles with original design aluminum hat front rotors or optional design full cast front rotors. Confirm the vehicle year, model, and axle position against the fitment list before installation. Part number 4504-31121 is listed for front and rear brake service, so both axle positions should be checked during brake inspection.

Quality Assurance

Dynamite Friction supplies this brake service kit as a matched rotor-and-pad solution for the listed BMW applications. The DFC Geospec rotor and 5000 Advanced Brake Pad combination is packaged for direct replacement use on the confirmed fitments.
