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 features rotors with a Geomet rust-resistant coating. This coating helps protect the rotor surface from corrosion and rust, extending the service life and maintaining braking efficiency. The vented design enhances heat dissipation during braking, reducing the risk of brake fade under normal driving conditions.

Technical Description and Fitment

The JBR1797EVC rotor is a vented disc brake rotor with a nominal thickness of 1.34 inches and an overall height of 1.95 inches. Its 12.91-inch outside diameter and five-lug hole pattern with a 4.50-inch bolt circle diameter make it compatible with front brake assemblies on Toyota RAV4, RAV4 Prime, and Sienna models. The vented design improves airflow to help dissipate heat generated during braking, which supports consistent brake performance and rotor longevity.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Toyota RAV4, RAV4 Prime, and Sienna
• Addresses brake noise caused by rust or corrosion buildup
• Improves braking consistency by reducing heat-related fade
• Restores proper rotor thickness for safe braking performance
• Prevents premature rotor surface degradation due to rust

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness meets manufacturer specifications and replace if below minimum thickness. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to inspect brake pads and replace them if worn to ensure optimal braking performance with the new rotor.

Quality Assurance

Power Stop rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The Geomet coating provides enhanced corrosion resistance to extend rotor life. While specific warranty details are not provided, Power Stop products typically undergo rigorous quality control to ensure durability and performance on compatible Toyota vehicles.
