Product Details

The DFC GEOSPEC Coated Rotor line focuses on coated brake rotor construction for service replacement applications. On this 604-42000 rotor, the vented design supports front axle braking demands, while the coated surface helps protect exposed rotor areas during normal service conditions. The dimensional specs are important for proper brake fitment, including the 327 mm outside diameter, 30 mm nominal thickness, and 28.5 mm discard thickness. This rotor is a direct-fit option for Jeep Grand Cherokee front brake service and Jeep Commander front brake replacement where the listed dimensions and bolt pattern match the vehicle.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues It Can Address

• Front brake pulsation caused by worn or uneven rotor surfaces
• Brake noise related to rotor wear or surface condition
• Reduced braking consistency from rotors at or near discard thickness
• Service replacement needs for Jeep Grand Cherokee front brakes
• Service replacement needs for Jeep Commander front brakes

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and hub fitment before installation. Clean the hub mounting surface thoroughly to help the rotor seat evenly, and inspect pads, calipers, and hardware condition during brake service. After installation, follow the vehicle manufacturer’s brake bedding procedure to establish proper pad-to-rotor contact.
