Product Details

DFC built this brake service kit for BMW drivers who need a front rotor and pad replacement that matches OE-style fit, form, and function. The coated rotors are machined to tight tolerances, inspected for balance on vented designs, and checked against critical OE specifications before release. The ceramic pad formulation is developed for modern vehicle braking demands and is assembled with shims that support smoother, quieter operation. For BMW 340i, 435i, and 440i front brake service, 4512-31254 provides the core components needed for a proper brake job.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues This Kit Addresses

• Front brake rotor rust and surface corrosion
• Brake noise during stops
• Uneven pad wear from fatigued hardware
• Reduced braking smoothness from worn rotors
• Longer service time caused by oil-coated replacement rotors

Installation Notes

Compatible With front M Sport brake applications only. Verify rotor style before ordering, since some listed BMW models use optional full cast rotors or original design aluminum hat rotors. The rotors arrive dry and do not require cleaning before installation. Follow standard brake service procedures, inspect calipers and guide hardware during replacement, and complete a proper pad bed-in after installation.

Quality Assurance

DFC GEOSPEC rotors are manufactured to OE specifications, inspected for critical dimensions, and backed by a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and scorched for stable performance, while the hardware kit is engineered to OE-style standards for consistent operation.
