Technical Details and Specifications

The 980584PER rotor features a drum-in-hat design, integrating the parking brake mechanism within the rotor assembly. This design is common for the specified Lexus and Toyota models, providing a compact and efficient braking solution. The nominal thickness of 0.710 inches (18.050 mm) ensures the rotor can withstand wear over time, while the discard thickness of 0.630 inches (16.000 mm) indicates the minimum safe thickness before replacement is necessary. The mounting bolt hole circle diameter measures 150.100 mm (5.910 inches), ensuring proper alignment and secure installation on the vehicle hub.

Applications and Problem Solving

• Replacement for worn or warped rotors on Lexus Land Cruiser and LX570
• Restores braking performance on Toyota Sequoia and Tundra with drum-in-hat rotors
• Addresses brake pulsation caused by uneven rotor thickness
• Prevents brake fade during regular street driving conditions
• Ensures proper parking brake function integrated within the rotor

Installation Notes and Tips

When installing the Raybestos 980584PER rotor, ensure the mounting surface is clean and free of debris to maintain proper rotor alignment. Verify the mounting bolt hole circle diameter matches the vehicle hub specifications. It is recommended to replace brake pads simultaneously to optimize braking performance. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 0.630 inches (16.000 mm).

Quality Assurance and Warranty

Raybestos rotors undergo rigorous quality control to meet OEM standards for fit, form, and function. The 980584PER rotor is manufactured to provide consistent braking performance and durability. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
