Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to improve brake pad bite and reduce gas buildup during braking. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life in various driving conditions. This product line is designed to meet the specific braking needs of vehicles like the Chevrolet Cobalt, ensuring compatibility and performance.

Technical Specifications and Features

This disc brake rotor is vented to allow air to flow between the rotor surfaces, which helps dissipate heat generated during braking. The rotor’s directional surface, featuring both drilled holes and slots, aids in removing brake dust and gases, improving pad contact and reducing brake fade. The rotor has a nominal thickness of 20 mm and a discard thickness of 18 mm, indicating when replacement is necessary to maintain safe braking. The zinc silver hat finish offers rust resistance, protecting the rotor’s core components. With 5 bolt holes sized at 14.2 mm and a bolt circle diameter of 110 mm, this rotor fits securely on the Chevrolet Cobalt’s hub assembly.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Chevrolet Cobalt
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps eliminate brake noise caused by uneven rotor surfaces
• Addresses rust and corrosion issues with rust-resistant coating
• Enhances braking performance in wet or dusty conditions with slotted and drilled design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Use the correct torque specifications for the 5 lug bolts with 14.2 mm diameter to secure the rotor. The directional surface requires installation in the correct rotation direction to maintain optimal performance. It is recommended to replace brake pads when installing new rotors to ensure even wear and braking efficiency.

Quality Assurance

Dynamite Friction manufactures the 631-47038L rotor to meet industry standards for durability and performance. The rust-resistant zinc silver coating helps extend rotor life by protecting against corrosion.
