The Story
Brake Kit for BMW 640i xDrive
The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is built for the front and rear brake service on select 2014-2018 BMW 640i xDrive models. Part number 4504-31059 combines coated rotors and advanced friction pads in one disc brake kit for a complete brake refresh.
Key Features
- Disc brake kit with DFC GEOSPEC coated rotors and 5000 Advanced Brake Pads
- Fits 2014-2018 BMW 640i xDrive, front and rear
- Rotors are processed dry and ready to install
- Non-directional rotor finish supports even pad bed-in and smoother braking
- Brake pads are post-cured and scorched to reduce initial break-in time
- Premium rubber-steel-rubber shims help improve noise, vibration, and harshness control
- Part number 4504-31059 for application-specific brake service
Product Details
DFC GEOSPEC rotors use a coated silver-gray finish that helps resist rust better than conventional paint or zinc coatings. The rotors are machined to tight tolerances, built to G3000/G11H18 cast iron specifications, and inspected for balance and critical dimensions before release. The 5000 Advanced Brake Pads are formulated for stable friction performance, with post-curing and scorching steps that help deliver consistent stopping response from the first stop. This brake kit is a direct service solution for BMW 640i xDrive front and rear brake replacement, and part number 4504-31059 is also a useful reference when sourcing the correct kit for this platform.
Common Brake Service Issues
- Brake pulsation from worn or uneven rotors
- Noise during braking from aged pads or rotor surface wear
- Rust buildup on exposed rotor surfaces
- Extended stopping distance caused by worn friction material
- Uneven pad bed-in after brake service
Installation Notes
Fits 2014-2018 BMW 640i xDrive, front and rear. One fitment note lists an optional design for full cast disc brake rotors; another notes compatibility with aluminum hat rotors designed to original specifications and includes a disc brake pad wear sensor. Verify rotor style and sensor requirements against the vehicle before installation. Clean, dry rotors reduce prep time during brake service, and the non-directional finish supports a more even bed-in process.
Quality Assurance
DFC states that each rotor passes 100% inspection for critical attributes and that all vented rotors are balance-checked and corrected when needed. The rotors carry a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and assembled with premium shims to support consistent performance and NVH control.
