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

The DFC Brake Rotor - Drilled and Slotted - Silver 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, contributing to improved brake response and reduced fade. The silver zinc coating on the rotor hat provides 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 34 mm, with a discard thickness of 32 mm, indicating when replacement is necessary to maintain safe braking performance. The rotor features a directional surface pattern with both drilled holes and slots, which enhances braking efficiency by improving pad bite and reducing brake fade. The rotor's hat is finished in zinc silver, providing rust resistance, and the entire rotor is coated to further protect against corrosion. It includes five bolt holes with a diameter of 16.5 mm and a bolt circle diameter of 120 mm, matching the Cadillac CTS specifications.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Cadillac CTS
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets the minimum discard thickness of 32 mm. Clean the rotor surface to remove any protective coating or debris before mounting. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 120 mm bolt circle pattern. Proper torque specifications should be followed when securing the rotor to avoid warping. This rotor is directional; install it according to the indicated rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for the Cadillac CTS. The rust-resistant zinc silver coating and vented design contribute to durability and consistent braking performance. While no specific warranty information is provided, the rotor is designed for reliable service life when installed and maintained according to manufacturer guidelines.
