A Rotor Wear Bar is a component found in disc brake systems, specifically in brake rotors. It serves as a visual indicator of the wear level on the rotor surface and helps determine the need for rotor replacement or resurfacing. As the brake pads make contact with the wear bar during braking, the raised portion gradually wears down. The wear pattern on the wear bar serves as a reference for evaluating the thickness and condition of the rotor.

Attributes:
• Withstand the high temperatures generated during braking.
• Designed for easy installation on the rotor surface.

Applications:
A Rotor Wear Bar helps in monitoring the wear level of the brake rotors.
