Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced surface features such as drilled holes and slots. These features improve heat dissipation and help reduce brake fade under demanding conditions. The zinc silver hat finish provides corrosion resistance, extending rotor life. This product line is tailored for drivers seeking reliable braking components compatible with specific Volkswagen models.

Technical Description and Specifications

This disc brake rotor is vented to allow better airflow and cooling during braking, which helps maintain consistent performance. The rotor’s surface is both drilled and slotted, providing channels for gas and dust evacuation, improving pad bite and reducing the risk of glazing. The rotor has a nominal thickness of 22 mm and a discard thickness of 19 mm, indicating when replacement is necessary. The rotor’s overall diameter is 280 mm, with a height close to 49.5 mm, and it features a 65 mm center hole diameter. The zinc silver hat finish combined with a rust-resistant coating helps protect against corrosion, especially in harsh environments. The rotor includes 5 bolt holes arranged on a 112 mm bolt circle diameter, matching the Volkswagen Bora and Jetta specifications.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Volkswagen Bora and Jetta
• Improves heat dissipation to reduce brake fade during extended braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Addresses corrosion issues with rust-resistant coating for longer service life
• Enhances braking consistency with directional drilled and slotted design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 19 mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify bolt hole alignment with the 5-lug, 112 mm bolt circle diameter pattern specific to Volkswagen Bora and Jetta. 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 Volkswagen Bora and Jetta models. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, the rotor is designed for reliable, consistent braking performance under normal operating conditions.
