Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve water, gas, and dust evacuation from the braking surface. This design helps maintain consistent braking performance under demanding conditions. The zinc silver hat finish provides corrosion resistance, extending rotor life, while the vented rotor construction aids in heat dissipation to reduce brake fade.

Technical Description and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The directional slotted and drilled surface improves pad bite and helps channel away debris and moisture. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18 mm, ensuring safe replacement intervals. The rotor’s dimensions, including a 289 mm outside diameter and 64.4 mm height, are designed for precise fitment on compatible Toyota 4Runner and Pickup models. The zinc silver coating on the hat area provides rust resistance, which is critical for maintaining structural integrity and appearance over time.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions
• Minimizes rotor surface corrosion with rust-resistant coating
• Enhances pad bite and braking response with slotted and drilled design
• Ensures proper fitment and safety with exact bolt hole and diameter specifications

Installation Notes and Tips

• Verify compatibility with Toyota 4Runner and Pickup models before installation
• Check rotor thickness and replace if below discard thickness of 18 mm
• Ensure proper torque on all 6 bolts with 127 mm bolt circle diameter
• Inspect brake pads for wear and replace if necessary during rotor installation
• Clean rotor surface before installation to remove any protective coatings or debris
