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 aids in heat dissipation and gas venting, which can reduce brake fade during demanding driving conditions. The black zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This product line is tailored for drivers seeking reliable braking performance with enhanced durability.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to help dissipate heat generated during braking. The directional surface pattern, featuring both drilled holes and slots, improves water and debris evacuation from the rotor surface, maintaining consistent braking performance. The rotor's nominal thickness is 24 mm, with a discard thickness of 22 mm, ensuring safe replacement intervals. The zinc black finish on the hat section offers rust resistance, which is critical for maintaining structural integrity over time. The rotor includes five bolt holes with a bolt circle diameter of 114.3 mm, matching the fitment requirements for specified Mazda models.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Mazda 626, 929, and Protege
• Improves heat dissipation to reduce brake fade during extended braking
• Slotted and drilled design helps remove brake dust and water for consistent stopping power
• Rust-resistant coating prevents corrosion-related rotor damage
• Maintains proper braking performance under demanding driving conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 22 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify the bolt hole pattern and bolt circle diameter (114.3 mm) match the vehicle hub. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Mazda 626, 929, and Protege models. The rust-resistant zinc black coating and vented rotor design contribute to durability and consistent performance. While no specific warranty information is provided, the product is designed for reliable service life under normal operating conditions.
