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

This Power Stop product line features rotors with a genuine Geomet coating, which provides enhanced corrosion resistance compared to standard rotors. The front rotors in this line are vented to promote better heat dissipation during braking, helping to maintain consistent performance and reduce the risk of brake fade. The JBR1149EVC rotor is designed specifically for front axle applications on compatible Lexus vehicles, ensuring proper fit and function.

Technical Specifications and Features

The JBR1149EVC rotor has a nominal thickness of 30.00 mm and a discard thickness of 27.00 mm, indicating when the rotor should be replaced to maintain safe braking. Its vented design improves airflow, which helps dissipate heat generated during braking. The rotor measures 334.00 mm (13.10 inches) in outside diameter and features a mounting bolt hole circle diameter of 114.30 mm with 5 lug holes, matching the factory specifications for the listed Lexus models. The Geomet coating provides a protective layer against rust and corrosion, extending the rotor's service life.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Lexus GS350, GS430, GS450h, GS460, IS200t, IS300, and IS350
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps reduce rust buildup that can impair braking efficiency
• Improves heat management to prevent brake fade during heavy use
• Restores proper rotor thickness for safe and effective braking

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (27.00 mm) before installation
• Clean mounting surface to prevent rotor runout and vibration
• Torque lug nuts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to optimize rotor performance
• Follow vehicle-specific service manual for front rotor replacement procedures
