About the Power Stop - Rear Genuine Geomet Coated Rotor Line

This Power Stop product line focuses on rear rotors featuring a genuine Geomet coating, which provides enhanced rust resistance compared to uncoated rotors. The coating helps extend rotor life by protecting against environmental elements, making it suitable for vehicles like the Lexus Highlander and Toyota RX series that require dependable rear braking components.

Detailed Product Description

The JBR1910EVC rotor is a vented disc brake rotor constructed from full cast material, ensuring structural integrity under braking stress. Its vented design promotes efficient heat dissipation, reducing the risk of brake fade during extended use. The rotor measures 338.2 mm in outside diameter with a nominal thickness of 18.1 mm and a discard thickness of 16.5 mm, indicating when replacement is necessary. The smooth surface finish ensures even brake pad wear and consistent braking performance. Additionally, the rotor features a rust-resistant Geomet coating that helps prevent corrosion, maintaining rotor condition over time. The mounting bolt hole circle diameter is 114.3 mm with 5 lug holes, matching the specifications for rear brakes on compatible Lexus and Toyota models.

Common Applications and Problem Solving

• Replacement for worn or warped rear rotors on Lexus Highlander and Toyota RX350 series
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Prevents rust buildup that can lead to rotor pitting and reduced braking efficiency
• Improves heat management to reduce brake fade during heavy braking
• Restores proper rotor thickness for safe and effective braking

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the nominal thickness of 18.1 mm. Clean the rotor surface and hub mounting area to remove any debris or rust before mounting. Use proper torque specifications for the 5 lug bolts on the 114.3 mm bolt circle to secure the rotor. Since this rotor does not include an ABS tone ring, verify compatibility with your vehicle’s ABS system. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.

Quality Assurance

Power Stop rotors undergo rigorous quality control to meet OEM standards for fit, form, and function. The Geomet coating provides additional protection against corrosion, contributing to longer rotor life. While specific warranty details are not provided, Power Stop products are manufactured to deliver consistent performance and durability for Lexus Highlander and Toyota RX350 rear brake applications.
