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

This rotor is part of the Power Stop - Rear Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating offers enhanced corrosion resistance compared to standard rotors, helping to prevent rust buildup and maintain braking performance over time. The line is designed to meet or exceed OEM specifications for fit and function, making it a suitable replacement for rear disc brake rotors on compatible vehicles.

Technical Specifications and Features

The JBR1903EVC rotor is a solid type rotor, which means it does not have ventilation channels but provides a stable braking surface ideal for rear brake applications. Its nominal thickness is 0.43 inches (11.00 mm), with a discard thickness of 0.35 inches (9.00 mm), indicating when the rotor should be replaced to maintain safe braking. The rotor measures 12.00 inches (304.90 mm) in outside diameter and has an overall height of 1.38 inches (35.00 mm). It mounts using a 5-lug pattern with a bolt hole circle diameter of 4.50 inches (114.30 mm), ensuring proper fitment on Hyundai Santa Fe and Kia Sorento rear brake assemblies.

Common Applications and Problem Solving

• Replacement for worn or warped rear rotors on Hyundai Santa Fe and Kia Sorento
• Addresses rotor rust and corrosion issues with Geomet coating
• Restores braking performance and reduces brake noise or vibration
• Suitable for vehicles experiencing rotor thickness below safe limits
• Helps maintain consistent brake pad contact and stopping power

Installation Notes and Tips

When installing the Power Stop JBR1903EVC rotor, ensure the rotor surface is clean and free of any protective coatings before mounting. Verify the rotor thickness to confirm it meets or exceeds the nominal thickness specification. Use proper torque specifications for the 5-lug mounting pattern to avoid rotor warping. It is recommended to inspect brake pads and hardware during installation to ensure overall brake system integrity.
