brake rotor

Wheel's friction disc

A brake rotor is the flat metal disc that a vehicle's brake pads clamp against to slow or stop the wheels.

Also called a brake disc.

Rotors are mounted to the wheel hub and spin with the wheel; when you press the brake pedal, calipers squeeze the pads against the rotor's surface, converting motion into heat through friction.

The mechanic said my rotors were warped and needed resurfacing.
