How do I go about removing the front rotors

Hello,

If it has single rear wheel, there is nothing else keeps the rotor in place. It is likely just seized on the hub. You will have to use a mallet or hammer to tap on the rotor and get it to come loose.
If it has duel rear wheel, you will have to remove the hub plate before the rotor will come out. Keep in mind that you still might have to use a hammer to tap on the rotor to remove it.
