The vented rotor design enhances airflow to reduce heat buildup during braking, helping to maintain consistent stopping power and reduce the risk of brake fade. With a nominal thickness of 1.535 inches and a discard thickness of 1.420 inches, this rotor provides a clear service life indicator to ensure timely replacement. The 10 mounting bolt holes and corresponding bolt circle diameter of 7.250 inches allow for secure installation on compatible truck hubs. The overall height of 3.400 inches and outside diameter of 15.370 inches align with specifications for medium to heavy-duty truck models requiring conventional disc brake rotors.

Applications and Problem Solving

• Replacement rotor for trucks experiencing brake rotor wear or warping
• Addresses issues with brake fade due to overheating in heavy-duty use
• Suitable for trucks requiring vented rotors for enhanced heat dissipation
• Compatible with vehicles needing a 10-bolt mounting pattern and specific rotor dimensions
• Ideal for restoring braking performance on trucks with conventional drum-in-hat rotor setups

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 1.420 inches. Properly clean the mounting surface and verify bolt hole alignment with the 10-bolt pattern and 7.250-inch bolt circle diameter. Use appropriate torque specifications for mounting bolts to avoid rotor distortion. This rotor is designed for conventional drum-in-hat type applications, so verify compatibility with your truck’s brake system configuration prior to installation.
