Hi I am new to this forum so please go easy on me. I am trying to find some answers on why my the brake on the handle bars do not work when the ATV cold, but work a bit when the ATV is hot. I did open the brake fluid container on the handle bar an found it was half full so of course I filled it with DOT 4 break fluid. That did not make any difference it still works the same. I hope somebody out there will help me figure this out.
