The Story
Rear Brake Kit for BMW X3 and X4
The Dynamite Friction DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit is a rear disc brake service kit built for select BMW applications. Part number 4502-31272 combines coated rotors and matched friction material for a direct brake service on 2011-2014 BMW X3 and 2016-2018 BMW X4 rear positions.
Key Features
- Rear disc brake kit with rotors and pads in one package
- DFC GEOSPEC coated rotors with a silver-gray corrosion-resistant finish
- Dry-processed, dry-shipped rotors ready for installation
- OE-spec G3000/G11H18 cast iron rotor construction
- Non-directional rotor finish for more even pad bed-in and smoother braking
- 100% inspected rotors, including balance checks on vented units
- DFC 5000 Advanced pads are post-cured and scorched for stable friction performance
- Premium rubber-steel-rubber shims for improved noise, vibration, and harshness control
Product Line Details
The DFC GEOSPEC rotor line focuses on corrosion protection and OE-style fitment. The coated surface is designed to resist rust better than conventional paint or zinc finishes, while the machining process and non-directional finish support consistent contact with the brake pads. The 5000 Advanced pad line is formulated for stable friction output and reduced break-in effort, making this kit a practical choice for rear brake service on BMW X3 and BMW X4 models.
Detailed Description
Part number 4502-31272 is a rear brake kit engineered for 2011-2014 BMW X3 and 2016-2018 BMW X4 applications. The rotors are machined to tight tolerances, finished for quieter operation, and inspected to confirm critical dimensions meet OE specifications. The pads are built for stable performance from the first stop, with post-curing, scorching, and NVH-focused shims to support smoother everyday braking. This kit is a straightforward solution when servicing rear brakes on BMW X3 and BMW X4 vehicles that require a complete rotor-and-pad replacement.
What It Helps Address
- Rear brake pulsation caused by worn or uneven rotors
- Brake noise from aged pads or inconsistent pad contact
- Rust buildup on exposed rotor surfaces
- Extended stopping distance from worn friction material
- Brake service delays when rotors and pads are replaced separately
Installation Notes and Tips
Compatible With 2011-2014 BMW X3, rear and 2016-2018 BMW X4, rear. Verify rotor size, pad shape, and rear axle configuration before installation. The rotors are shipped dry and do not require oil removal before service. During installation, follow standard brake service procedures, clean mating surfaces, and complete a proper bed-in cycle for the new pads and rotors. Part number 4502-31272 should be matched to the vehicle’s rear brake specification before assembly.
Quality Assurance
DFC GEOSPEC rotors are manufactured to OE specifications and undergo 100% inspection of critical attributes. Vented rotors are balance-checked and corrected when needed. The rotors include a 12-month warranty against defects in material and workmanship. Part number 4502-31272 is built as a complete rear brake service kit for BMW X3 and BMW X4 rear applications.
