Lifted 98 TXT brakes grabbing

I just got my first cart yesterday. 1998 TXT lifted on 22s. Guy I got it from recently lifted it, thinks a brake pad may need replaced. Seems more than that. When you apply the brakes, it does a nose dive, grabs really hard. Could this be the cable and/or axle? Think I read that is possible, how do I diagnose?
Thanks
