hello, I have a 91 Bayou 300 4x4 and the front brakes seem to be hanging up a little, I have tried to get the calipers off but have had no luck. Seems that every bolt I need to get loose is very stuck. I just got this quad a little while ago and from what I can tell I think it has spent all its life sitting outside. Anyone have any ideas to get the calipers off, I have soaked them with penetrating oil and that seems to not make a difference. Thanks
