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 feature a combination of drilled holes and slots on the braking surface. This design improves water and gas dissipation during braking, which helps maintain consistent stopping power. 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 rotors that balance performance and durability for specific vehicle applications.

Technical Specifications and Features

This vented rotor measures 285 mm in outside diameter and 42.1 mm in overall height, ensuring compatibility with the braking system of Cadillac BLS and Saab 9-3 models. The rotor’s directional drilled and slotted surface enhances brake pad bite and helps reduce brake fade by allowing heat and gases to escape efficiently. The zinc black finish on the hat offers rust resistance, which is critical for maintaining rotor integrity over time. With five bolt holes spaced on a 110 mm bolt circle diameter, this rotor fits securely on the designated vehicles. The nominal thickness of 24.8 mm and discard thickness of 22 mm provide clear service limits for maintenance.

Applications and Problem Solving

• Replacement for worn or warped rotors on Cadillac BLS and Saab 9-3
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet conditions
• Prevents rust and corrosion on rotor hats for longer service life
• Restores proper rotor thickness to ensure safe braking distances

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the bolt hole pattern matches the vehicle’s hub assembly (5 bolt holes, 110 mm bolt circle diameter). Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously to optimize braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 22 mm.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Cadillac and Saab vehicles. The rust-resistant coating and vented design contribute to durability and consistent braking performance. While no specific warranty information is provided, the product is engineered for reliable service within the recommended maintenance parameters.
