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

This rotor is part of the Power Stop - Front Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating enhances corrosion resistance without compromising braking performance, making it suitable for vehicles exposed to moisture and road salts. The vented rotor design helps maintain optimal operating temperatures, reducing the risk of brake fade during extended use.

Technical Specifications and Features

The JBR779EVC rotor features a vented design that improves airflow and heat dissipation, essential for maintaining brake efficiency and rotor longevity. The nominal thickness of 0.94 inches (24.00 mm) ensures compatibility with OEM specifications, while the discard thickness of 0.88 inches (22.40 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height measures 1.80 inches (45.30 mm), and the outside diameter is 10.10 inches (256.00 mm), matching the exact fitment requirements for Mitsubishi Lancer and Mirage front brakes. The mounting bolt hole circle diameter is 3.90 inches (100.00 mm) with 4 stud/lug holes, ensuring secure installation.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Mitsubishi Lancer and Mirage
• 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
• Reduces brake fade during extended or heavy braking conditions

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify that the mounting bolt hole circle diameter and stud/lug hole quantity match your vehicle’s specifications. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 0.88 inches (22.40 mm) to ensure safety and effectiveness.
