2000 or 2003 Yamaha big bear front brakes issue

So the atv is working good decent machine for being older. We bought it off a guy selling it so he is like got some issues with it.
1st the starter is going. It makes nasty metal on metal noises and I haven’t pulled it off yet to see if there is damage to the teeth.
2nd and most important to me is the front brakes. When riding the atv I will use the front brakes cause the back ones are gone. But after riding for a bit the front brakes get stuck. They will not disengage so I’m riding around with the front brakes enguaged sightly the atv still runs and drives but the brakes are sticking. They get so hot the brakes start smoking you know when they are sticking cause you let off the throttle and almost come to a dead stop. They stay this way for a bit then stop sticking it happens almost every time I run it. I can tell you that both sides are sticking cause when I splashed with water both sides boiled off.
Anyone run into this problem before
