How to Install Disc Brake Rotors

Disc brake rotors are the round, metal plates that the brake pads squeeze and to which the calipers are mounted. Some rotors secure to the axle by the wheel and some rotors are secured to the axle by bolts. When installing the rotors, you must buy rotors that are the correct size for your vehicle. You can buy the rotors at any auto store. When you buy the rotors, take care to get the ones designed for your make and model vehicle.
