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 for improved brake pad cleaning and heat management. The black zinc coating on the rotor hat provides corrosion resistance, extending rotor life in various driving conditions. This product line is designed to meet the demands of Mazda vehicles requiring reliable vented rotors with directional braking surfaces.

Technical Description and Specifications

This disc brake rotor is vented to allow better airflow and heat dissipation during braking, reducing the risk of brake fade. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water from the braking surface, improving contact between the pad and rotor. The directional design ensures optimal performance when installed correctly. The rotor’s nominal thickness is 28 mm, with a discard thickness of 26 mm, indicating when replacement is necessary to maintain braking safety. The zinc black finish on the rotor hat offers rust resistance, while the plain disc finish maintains consistent braking friction.

Applications and Problem Solving

• Reduces brake fade during aggressive or prolonged braking
• Improves braking performance in wet or dusty conditions
• Prevents rotor corrosion with rust-resistant coating
• Maintains proper braking contact with directional slotted and drilled surface
• Ensures safe replacement timing with clear discard thickness specification

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction for optimal performance. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter specific to Mazda 6, CX-5, and CX-9 models. Check rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 28 mm and is above the discard thickness of 26 mm. Proper torque specifications should be followed to avoid warping or damage.

Quality Assurance

Dynamite Friction manufactures the 633-80078R rotor to meet OEM standards for fitment and performance on Mazda vehicles. The rust-resistant zinc black coating and vented rotor design contribute to durability and consistent braking.
