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

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to evacuate gases, dust, and water more efficiently than plain rotors, which can improve braking consistency under demanding conditions. The black zinc coating on the rotor hat provides additional corrosion resistance, extending the rotor's service life especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat generated during braking. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring safe replacement intervals. The rotor features a directional surface type with both drilled holes and slots, which helps maintain clean pad contact and reduces brake fade. The rotor’s hat is finished in zinc black for rust resistance, complementing the plain disc finish. It includes 5 bolt holes with a diameter of 16.1 mm and a bolt circle diameter of 120 mm, matching the stud/lug hole pattern for Chevrolet Equinox and GMC Terrain vehicles.

Common Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Chevrolet Equinox and GMC Terrain
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent rust and corrosion on rotor hats for longer durability
• Enhances braking performance in wet conditions by evacuating water and debris
• Maintains consistent braking feel with directional slotted and drilled design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18.4 mm before installation. Clean the rotor surface to remove any protective coating or residue prior to mounting. Verify the bolt hole pattern matches the vehicle’s hub (5 holes, 16.1 mm diameter, 120 mm bolt circle). Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 633-48058L rotor to meet or exceed OEM specifications for Chevrolet Equinox and GMC Terrain models. The rust-resistant zinc black coating on the rotor hat helps extend service life. While no specific warranty information is provided, Dynamite Friction products are designed for durability and consistent braking performance under normal operating conditions.
