The Story
Front Brake Kit for BMW 125i and 128i
DFC Friction part number 4502-31187 is a front disc brake kit built for select 2012-2013 BMW 125i and 128i applications. It combines DFC GEOSPEC coated rotors with 5000 Advanced brake pads for a complete front brake service in one package.
Key Features
- Front disc brake kit with rotors and pads
- Compatible with 2012-2013 BMW 125i and 128i front applications
- 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
- 5000 Advanced pads are post-cured and scorched for stable friction performance
- Premium rubber-steel-rubber shims help reduce noise, vibration, and harshness
- Part number 4502-31187 for front brake service on BMW 125i and 128i
Product Details
DFC GEOSPEC rotors are machined to tight tolerances, then finished with a non-directional surface to support consistent pad contact and quieter stops. The coated surface is designed to resist rust better than conventional paint or zinc finishes, and the dry packaging eliminates the need to clean oil from the rotor before installation. The 5000 Advanced pads are formulated for stable friction, with post-curing and scorching steps that reduce initial break-in time and improve first-stop response. Together, these components provide a service-ready front brake solution for BMW 125i and BMW 128i models.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Brake Issues This Kit Can Address
- Front brake pulsation from worn or uneven rotors
- Noise caused by pad wear or inconsistent rotor finish
- Reduced stopping performance from aged friction material
- Rust buildup on exposed rotor surfaces
- Extended service time from rotors that require cleaning before installation
Installation Notes
Fits 2012-2013 BMW 125i, front. Fits 2012-2013 BMW 128i, front. Verify rotor size, caliper condition, and pad wear sensors before installation. The rotors are shipped dry and ready to install, and the non-directional finish supports a more even bed-in process after service. Part number 4502-31187 is intended for front axle brake replacement only.
Quality Assurance
Each DFC GEOSPEC rotor is inspected for critical dimensions and balance, with vented rotors electronically mill-balanced when needed. The rotors are built to OE specifications and include a 12-month warranty against defects in material and workmanship.
