Different types of rotors: one piece or two?
One Piece: This type of rotor (right) is used for most applications. The original rotor was a cast 2 piece rotor. We now reproduce this rotor as a one piece “Unicast.” This rotor is better than the original and has improvements to handle more heat. We add slotting to improve rotor life. The slots sweep the pads clean, allowing the rotor to run cooler.
