Product Line Details: Power Stop - Front Genuine Geomet Coated Rotor

The Power Stop - Front Genuine Geomet Coated Rotor line focuses on providing rotors with a durable Geomet coating that resists rust and corrosion. This coating helps maintain rotor integrity and appearance over time, especially in environments prone to moisture and road salt. The vented rotor design enhances heat dissipation, reducing the risk of brake fade during extended use. This product line is designed to meet or exceed OEM specifications for Toyota 4Runner and Tacoma front brake applications.

Technical Specifications and Features

This disc brake rotor is vented to improve airflow and cooling during braking, which helps maintain consistent brake performance. The nominal thickness of 0.87 inches (22.10 mm) ensures sufficient material for durability, while the discard thickness of 0.79 inches (20.00 mm) indicates when the rotor should be replaced. The rotor measures 11.70 inches (297.00 mm) in outside diameter and has an overall height of 2.80 inches (70.70 mm). It features a mounting bolt hole circle diameter of 5.50 inches (139.70 mm) and includes 6 stud/lug holes, matching the factory specifications for Toyota 4Runner and Tacoma front brakes.

Applications and Problem Solving

• Replacement for worn or warped front rotors on Toyota 4Runner and Tacoma
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps restore proper braking performance and pedal feel
• Prevents rust and corrosion-related rotor damage in humid or salty environments
• Improves heat dissipation to reduce brake fade during heavy use

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.79 inches before installation. Clean the rotor surface to remove any protective coating residue before mounting. Use proper torque specifications for the 6 lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. Verify compatibility with Toyota 4Runner and Tacoma front brake assemblies prior to installation.
