Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is a disc brake rotor designed to enhance braking efficiency and maintain consistent performance under demanding conditions. The rotor features a slotted and drilled surface type that helps to dissipate heat and gases generated during braking, reducing the risk of brake fade. Its directional brake surface ensures optimal contact with brake pads, improving stopping power for Acura MDX, Honda Passport, and Pilot vehicles. The rotor’s zinc silver hat finish includes a rust-resistant coating, which helps protect against corrosion and extends the rotor’s service life. With a nominal thickness of 11 mm and a discard thickness of 9 mm, this rotor provides clear wear limits for safe replacement timing. The rotor’s five bolt holes, each 14.6 mm in diameter, and a bolt circle diameter of 120 mm, ensure precise fitment and secure mounting.

Compatible Vehicles and Applications

• Designed specifically for Acura MDX models requiring a 330 mm rotor diameter
• Compatible with Honda Passport vehicles needing a drilled and slotted rotor
• Fits Honda Pilot models with matching bolt pattern and rotor dimensions
• Ideal for replacing worn or damaged rotors to restore braking performance
• Addresses issues such as brake fade, rotor warping, and uneven pad wear

Installation Notes and Tips

When installing the Dynamite Friction 631-58038L rotor, ensure the rotor surface is clean and free of any contaminants before mounting. Verify that the bolt hole pattern and center hole diameter match the vehicle hub for proper alignment. Use a torque wrench to tighten lug nuts to manufacturer specifications to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure even wear and optimal braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 9 mm.
