BRAKE DISC - VENTED - FRONT & REAR

Brake Discs, also known as Rotors, are the rotating part of a wheel's disc brake assembly. The material is typically cast iron & the designs are varied, some are solid, others are ventilated (hollowed out) with fins or vanes joining together the disc's two contact surfaces. Ventilated discs helps to dissipate heat & commonly used on more heavily loaded front axles. A brake caliper squeezes the brake pads against the disc to create friction. The friction created slows the rotation of a wheel reducing its rotational speed and bring to a stop.
