Product Details

This DFC brake service kit is built around OE-style rotor dimensions and friction characteristics for rear brake service on the Acura MDX. The rotors use G3000/G11H18 cast iron and are machined to tight tolerances, then finished with a non-directional surface to support consistent pad contact. The coated rotor surface is designed to resist rust better than conventional paint or zinc finishes, while the 5000 Advanced pads are post-cured and scorched to deliver stable friction performance from the first stop. Part number 4502-58046 is a direct rear brake kit solution for 2017-2020 Acura MDX models.

Common Brake Service Issues

• Rear brake pulsation from worn or uneven rotors
• Squealing or vibration during braking
• Rust buildup on exposed rotor surfaces
• Reduced braking consistency from worn pad friction material
• Extended stopping distance caused by brake wear

Installation Notes

Compatible With 2017-2020 Acura MDX rear brake service. The rotors are shipped dry and ready to install, which helps reduce prep time during a standard brake job. Follow OE service procedures, inspect calipers and related wear items during replacement, and bed the pads according to the vehicle manufacturer’s recommendations for the best initial brake feel.

Quality Assurance

Each rotor is 100% inspected for critical dimensions and balance, with vented rotors corrected as needed through electronic mill-balancing. DFC states that every rotor meets OE specifications and includes a 12-month warranty against defects in material and workmanship.
