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 to improve braking efficiency and rotor cooling. This product line is designed to reduce brake fade and maintain consistent performance under demanding conditions. 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 more effectively during braking. The directional slotted and drilled surface pattern helps channel away water, dust, and brake dust, improving pad contact and braking response. The rotor's nominal thickness is 24 mm, with a discard thickness of 23 mm, ensuring safe replacement intervals. The rotor features five bolt holes with a diameter of 14.2 mm and a bolt circle diameter of 110 mm, matching the wheel hub specifications of Chevrolet Cobalt and Pontiac G5 models.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Chevrolet Cobalt and Pontiac G5
• Improves heat dissipation to reduce brake fade during extended braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant zinc silver coating
• Enhances brake pad bite and reduces brake noise through slotted and drilled design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 23 mm before installation. Clean the rotor surface to remove any protective coating or debris before mounting. Verify bolt hole alignment with the vehicle hub using the 110 mm bolt circle diameter and 14.2 mm bolt hole diameter. Proper torque specifications should be followed when securing the rotor to avoid warping. This rotor is directional; install with the correct orientation to maximize performance benefits.

Quality Assurance

Dynamite Friction manufactures the 631-47036L rotor to meet or exceed OEM specifications for Chevrolet Cobalt and Pontiac G5 vehicles. The rust-resistant coating and vented design contribute to durability and consistent braking performance.
