I have a friend with a 91 blaster bored 20 over willing to sell it to me for $500 it runs good and looks good for a 91 but the front brakes dont work that good its like they dont wanna let go, and the rear brakes dont work at all its like the cable is frozen. also the tires are stock from 91. Should I take it? This would be my first quad. Any input would be great.
