2003 honda Rancher trx350 footbrake stuck

Hi guys on my 03 trx350 my foot brake is stuck! I took off everything that’s holding it on and it wont slide off the pivot arm so is it worth fixing or should I just try to use my hand brake? the hand brake was real lose feeling before and even holding it in it wouldn’t slow the 4 wheeler down and I need some kinda brakes on It fronts not working eather. The backs has brand new pads they just suck kinda reminds u of a bycycle that used brake pads when u change them out they never worked as good as they did from the factory
