Product Details

DFC’s GEOSPEC rotor line uses a silver-gray protective coating that resists rust better than conventional paint or zinc-style finishes. The rotors are machined to OE-level tolerances, inspected for critical dimensions, and balanced where required. The 5000 Advanced Brake Pads are formulated for axle-specific braking needs and are prepared to reduce initial break-in time while delivering consistent pedal feel. This part number, 4502-76139, is a direct rear brake service solution for Corolla iM, Scion iM, Scion xB, Toyota Matrix, and Pontiac Vibe rear brake maintenance.

Common Brake Issues This Kit Can Address

• Rear brake noise such as squeal or light vibration
• Rust buildup on exposed rotor surfaces
• Uneven or inconsistent rear braking response
• Reduced stopping performance from worn pads and rotors
• Longer service time caused by uncoated, oil-covered replacement rotors

Installation Notes

Confirm rear axle fitment before ordering, since this kit is application-specific. The rotors are processed dry and do not require cleaning before installation. For best results, follow the vehicle manufacturer’s brake service procedure and perform a proper pad bed-in after installation. Part number 4502-76139 is listed for rear use only on the vehicles shown above.

Quality Assurance

DFC states that the rotors are manufactured to OE specifications, 100% inspected for critical attributes, and backed by a 12-month warranty against defects in material and workmanship. The pads are post-cured and scorched for stable friction characteristics, with premium shims added to improve NVH control.
