Motorcycle Parts Racing Ride Wheel Brake Disc Rotor Stainless Steel Fit for Triumph DAYTONA 600 03-04 REAR - R
In rim brake systems, the wheel acts like the brake rotor. Disc brake rotors are much smaller than wheels, which means more force must be applied from the brake pad to the rotor in order to create a sufficient amount of stopping power. This allows for better control of the braking forces because you have a broader range of force that can be applied to the disc rotor, creating a smoother transition from no braking to some braking to hard braking to locking up the wheels.
The brake rotor or brake disk is the main rotating part of the disk brake assembly. It is the component by which the brake caliper clamps its hold to stop the wheel rotation. It is hard wearing and resists the high temperatures that occur during braking. Its manufacturer who will specify the minimum thickness for the rotor. It is generally made of cast iron. In high performance vehicles composite materials such as ceramics or carbon fiber used to make rotors. Since some of the rotors have directional vanes they can be fitted to only one side of the vehicle.
If you find your disc in damaged condition get it changed instead of repairing it.
