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 bite and gas evacuation. 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 drivers seeking reliable braking performance on Mazda vehicles such as the Mazda 6, CX-5, and CX-9.

Technical Specifications and Features

This disc brake rotor is vented to promote better heat dissipation during braking, reducing the risk of brake fade. The directional surface with drilled holes and slots helps channel away water, dust, and gases generated during braking, maintaining consistent pad contact. The rotor’s nominal thickness is 28 mm, with a discard thickness of 26 mm, indicating when replacement is necessary to maintain safety and performance. The zinc black finish on the rotor hat offers rust resistance, which is critical for durability in wet or corrosive environments.

Applications and Problem Solving

• Improves braking performance on Mazda 6, CX-5, and CX-9 vehicles
• Reduces brake fade during heavy or repeated braking
• Helps prevent rotor corrosion with rust-resistant coating
• Maintains consistent brake pad contact through slotted and drilled design
• Supports safe replacement with clear discard thickness specification

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter. 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 633-80078L rotor to meet industry standards for durability and performance. The rust-resistant zinc black finish and vented design contribute to long service life. Warranty information is available from the manufacturer or distributor and should be reviewed prior to installation.
