Product Details

DFC GEOSPEC Rotors with 5000 Advanced Brake Pads are engineered as a matched service kit for front brake replacement. The coated rotors are machined to tight tolerances, inspected for critical dimensions, and balanced where required to support quiet, stable braking. The pad compound is formulated for consistent friction, with post-curing and scorching used to reduce initial break-in time and improve stopping response from the first stop. This part number, 4502-63189, is a practical choice for drivers servicing a Mercedes-Benz CLA250 front brake kit, a Mercedes-Benz GLA250 front brake kit, or an INFINITI QX30 front disc brake kit.

Common Problems This Kit Can Address

• Brake pulsation from worn or uneven front rotors
• Squealing or noise from aged brake pads
• Reduced stopping performance from pad wear
• Rust buildup on exposed rotor surfaces
• Longer service time caused by uncoated rotors that require prep
