Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced surface features to improve braking performance and rotor longevity. The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the zinc silver hat finish provides corrosion resistance. This product line is tailored for drivers seeking a balance between durability and effective heat management in their braking system.

Technical Description and Specifications

This disc brake rotor is a solid type with a nominal thickness of 10 mm and a discard thickness of 8.5 mm, ensuring it meets safety standards for replacement intervals. The rotor’s surface is both drilled and slotted, which aids in heat dissipation and helps maintain clean contact between the brake pad and rotor surface. The rotor features a plain disc finish and a zinc silver hat finish that includes a rust-resistant coating to protect against corrosion. It has 5 bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 62 mm, designed specifically for the Toyota Highlander. The directional brake surface ensures proper installation orientation for optimal braking performance.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Toyota Highlander
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent rust and corrosion on rotor surfaces
• Maintains consistent braking performance under varied driving conditions
• Addresses noise and vibration issues caused by uneven rotor surfaces

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated by the manufacturer. Verify that the bolt hole pattern matches the vehicle’s hub (5 bolt holes, 114.3 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 8.5 mm. Clean the rotor surface to remove any protective coatings or residues before mounting brake pads. Proper torque specifications should be followed when securing the rotor to avoid warping.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Toyota Highlander models. The rust-resistant coating and zinc silver hat finish contribute to the rotor’s durability. While specific warranty details are not provided, Dynamite Friction products typically adhere to industry standards for quality and reliability.
