The Story
Rear Brake Kit for BMW X3 and X4
The DFC GEOSPEC Rotors with 5000 Advanced Brake Pads kit, part number 4502-31273, is a rear disc brake kit built for select BMW applications. It combines coated rotors and matched friction material for a service-ready brake replacement on the rear axle.
- Rear disc brake kit with rotors and pads
- Fits 2015-2017 BMW X3, rear
- Fits 2015-2018 BMW X4, rear
- DFC GEOSPEC coated rotors with silver-gray corrosion-resistant finish
- Dry-processed rotors arrive ready to install
- Non-directional rotor finish supports even pad bed-in and smoother braking
- DFC 5000 Advanced pads are post-cured and scorched for stable friction performance
- Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
Product Line Details
DFC GEOSPEC rotors are machined to OE-style tolerances using G3000/G11H18 cast iron and inspected for balance and critical dimensions. The coating is designed to resist rust better than conventional paint or zinc finishes, while the dry packaging avoids the need to clean oil from the rotor before installation. The 5000 Advanced pad line is formulated for axle-specific friction needs and is assembled for consistent pedal feel and quieter operation.
Common Brake Service Issues
- Rear brake noise during stops
- Rotor rust and surface corrosion
- Uneven pad bedding after brake service
- Brake vibration from worn rear rotors
- Reduced stopping consistency from aged pads
Installation Notes
Use this kit for rear brake service on the listed BMW X3 and BMW X4 applications. Clean the rotor friction surfaces only as needed before installation, and follow standard brake bedding procedures after service. Verify rear axle fitment by year and model before ordering. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Quality Assurance
Each rotor is 100% inspected after machining to confirm critical dimensions and OE specifications. Vented rotors are balance-checked and corrected when required. DFC backs the rotors with a 12-month warranty against defects in material and workmanship. Part number 4502-31273 is built for dependable rear brake replacement on BMW X3 and BMW X4 service applications.
