Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, which helps prevent brake fade during extended use. The directional drilled and slotted surface improves water, dust, and gas evacuation from the braking surface, enhancing pad contact and braking efficiency. The rotor’s zinc black hat finish and rust-resistant coating extend the rotor’s lifespan by protecting against corrosion. With a nominal thickness of 31.8 mm and a discard thickness of 29 mm, this rotor maintains structural integrity and safety throughout its service life.

Applications and Problem Solving

• Reduces brake fade caused by overheating during heavy braking
• Improves braking response in wet or dusty conditions
• Prevents rust and corrosion on the rotor surface and hat
• Maintains consistent braking performance for Lexus 4Runner, GX460, and Toyota Land Cruiser
• Addresses uneven pad wear by providing a smooth, directional braking surface

Installation Notes and Tips

Ensure the rotor is compatible with your vehicle’s bolt pattern and dimensions before installation. The 6 bolt holes and 6 lug holes with a bolt circle diameter of 139.4 mm must match your vehicle’s hub. Clean the rotor surface before mounting to remove any protective coatings or residues. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.
