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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to evacuate gases, dust, and water more efficiently, which can improve braking consistency and reduce fade. The silver zinc coating on the rotor hat provides additional rust resistance, extending the rotor's service life in various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat generated during braking. The rotor's directional surface pattern, featuring both drilled holes and slots, is optimized to maintain clean contact with brake pads and improve stopping power. The rotor measures 297 mm in outside diameter and 70.5 mm in height, with a center hole diameter of 108 mm. It includes six bolt holes with a 14.6 mm diameter and a bolt circle diameter of 139.7 mm, ensuring proper fitment on compatible Toyota 4Runner and Tacoma models.

Applications and Problem Solving

• Replaces worn or warped rotors on Toyota 4Runner and Tacoma vehicles
• Helps reduce brake fade during heavy or repeated braking
• Improves heat dissipation to prevent rotor cracking or glazing
• Enhances braking performance in wet or dusty conditions
• Protects against rust and corrosion for longer rotor life

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment and torque specifications according to Toyota manufacturer guidelines. Proper bedding-in of brake pads after installation is recommended to optimize braking performance and rotor longevity.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver finish on the rotor hat helps maintain structural integrity over time. While no specific warranty information is provided, the product is designed for reliable performance on Toyota 4Runner and Tacoma vehicles when installed and maintained properly.
