Key Features
- Front disc brake kit with DFC GEOSPEC coated rotors and 5000 Advanced brake pads
- Dry-shipped rotors arrive ready to install without oil removal
- Silver-gray rotor coating helps resist rust and corrosion
- G3000/G11H18 cast iron rotor construction for OE-style durability and stability
- Non-directional rotor finish supports even pad bed-in and quieter braking
- 100% post-cured and scorched pads for stable friction performance from the first stop
- Rubber-steel-rubber shims help reduce noise, vibration, and harshness
- 12-month warranty against defects in material and workmanship
Product Line Details
DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are designed as a matched brake service solution. The rotor side focuses on corrosion protection, OE-spec machining, and balance inspection, while the pad side emphasizes consistent friction, reduced break-in time, and improved NVH control. This makes the kit a practical choice for front brake service on BMW models that require precise braking feel and stable performance.
Detailed Description
Part number 4502-31083 is a front brake kit engineered for selected BMW vehicles with standard brakes, including applications that use original design aluminum hat rotors or optional design full cast rotors. The coated DFC GEOSPEC rotors are machined to tight tolerances, inspected for critical dimensions, and finished to promote smooth, quiet stops. The 5000 Advanced pads are post-cured and scorched to help deliver consistent friction and stronger initial bite after installation. Fits 2016-2020 BMW 740i, front; Fits 2017-2020 BMW 740i xDrive, front; Fits 2020-2021 BMW 540i, front; Fits 2020-2021 BMW 540i xDrive, front; Fits 2020-2021 BMW 840i, front; Fits 2020-2021 BMW 840i Gran Coupe, front; Fits 2020-2021 BMW 840i xDrive, front; Fits 2020-2021 BMW 840i xDrive Gran Coupe, front; Fits 2019-2020 BMW M850i xDrive, front; Fits 2019-2020 BMW X7, front; Fits 2018-2019 BMW 640i xDrive Gran Turismo, front; Fits 2017-2019 BMW 740e xDrive, front; Fits 2018 BMW 740e xDrive, front.
What This Brake Kit Helps Address
- Front brake pad wear and reduced stopping performance
- Rotor rust on exposed braking surfaces
- Brake noise, vibration, and harshness during stops
- Uneven pad bed-in after rotor replacement
- Service time spent cleaning oil-coated rotors before installation
Installation Notes and Tips
Verify rotor style and brake package before ordering, especially on BMW models with standard brakes, original design aluminum hat rotors, or optional design full cast rotors. This front kit is intended for axle-level brake service, so compare the vehicle’s existing rotor and pad configuration to the fitment notes. A proper bed-in procedure after installation helps the pads and rotors seat evenly.
Quality Assurance
DFC processes each rotor through machining, balance inspection, and final critical-attribute checks to meet OE specifications. The 5000 Advanced pads are post-cured, scorched, and assembled with premium rubber-steel-rubber shims for consistent performance and improved noise control. Every rotor includes a 12-month warranty against defects in material and workmanship. Part number 4502-31083 is a direct front brake service solution for compatible BMW applications.
