Product Line Details

The DFC GEOSPEC rotor line is focused on corrosion protection and installation efficiency. The coated surface helps resist rust better than conventional paint or zinc finishes, while the dry packaging eliminates the need to clean oil from the rotor before service. The 5000 Advanced Brake Pads are formulated for stable friction performance and consistent pedal feel across a range of driving conditions.

Detailed Description

Part number 4502-31140 is a rear brake kit for BMW 318i, 318is, 323i, 323is, 325i, 325is, 328i, and 328is applications from 1991 through 1999. It is a practical choice for drivers replacing worn rear brake components on E36-era BMW models and looking for an OE-style service kit with coated rotors and matched pads. The rotors are machined to tight tolerances, finished non-directionally for quieter operation, and inspected for balance and critical dimensions before release.

The included brake pads are post-cured and scorched to support stable friction from the first stop, while the shim design helps reduce noise, vibration, and harshness. This rear brake kit is a direct service option for BMW 318i rear brake replacement, BMW 325i rear disc brake service, and BMW 328i rear rotor and pad replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Kit Can Address

• Rear brake noise, squeal, or vibration
• Rust buildup on exposed rotor surfaces
• Uneven braking feel from worn rotors and pads
• Reduced stopping performance from aged friction material
• Brake service needs on BMW 318i, 325i, or 328i rear axles

Installation Notes and Tips

Compatible With 1991 BMW 318i and 318is rear vehicles built from 11/91, plus 1992-1999 BMW 318i, 318is, 325i, 325is, 328i, 328is, 323i, and 323is rear applications as listed. Verify rotor size, axle configuration, and vehicle production date before ordering. Clean the hub mounting surface, torque fasteners to factory specification, and follow a proper brake bed-in procedure after installation.

Quality Assurance

Each DFC GEOSPEC rotor is inspected for balance and critical dimensions to meet OE specifications, and every rotor includes 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 noise control.
