Product Details

The DFC GEOSPEC rotor line uses a silver-gray protective coating that is designed to hold up better against rust than conventional paint or zinc finishes. Each rotor is machined to tight tolerances, finished with a non-directional surface, and inspected for balance and critical dimensions to meet OE-style specifications. The 5000 Advanced pad line is formulated for consistent friction, with post-curing and scorching steps that reduce initial break-in time and help deliver stopping performance from the first stop. For shoppers searching for a rear brake kit for a 2002-2005 Ford Explorer or 2002-2005 Mercury Mountaineer, 4502-99132 provides the matched components needed for a complete rear brake service.

Common Brake Issues This Kit Can Address

• Rear brake pulsation from worn or uneven rotors
• Brake noise caused by aged pads or rotor surface wear
• Reduced stopping performance from thin or heat-affected brake parts
• Rust buildup on exposed rotor surfaces
• Longer pedal travel from worn rear brake components

Installation Notes and Tips

Rear brake replacement on these vehicles is typically performed as a complete axle service. Before installation, verify rotor size, caliper condition, and pad wear pattern on the existing rear brake system. The GEOSPEC coating is processed dry and does not require cleaning before installation; the coating is removed naturally by the brake pads during normal use. For best results, follow the vehicle manufacturer’s brake service procedure and perform a proper pad bed-in after installation.

Quality Assurance

Each rotor in this kit is manufactured to OE specifications, inspected for critical dimensions, and backed by a 12-month warranty against defects in material and workmanship. Part number 4502-99132 is built as a complete rear brake service solution for Explorer and Mountaineer owners who need a matched rotor-and-pad replacement.
