We went riding yesterday, it was no warmer than 20. Was going down a steep hill and oops there goes the front brakes. Back end was heading toward the front. Our buddy in another ranger was in front of us and wham hit him in the rear. Boy where they surprised. All is ok no damage. We think the front brakes may have froze up after going through some water. Haven't had a chance to inspect them way to cold last night. It seems unlikely that they would be warn out we only have 780 miles on the machine. Anyone else have an idea?
