My little brother has a 2005 Yamoto 110 4-wheeler. He got it a few months ago. But we think his brake line was yanked off. But not sure if its 100% the brake line. My husband looked and hes not 100% sure its the brake line. Its a skinny gray line on the left hand side. Its not been cut, but more like torn...Anyone know? Or any help to what it could be?

 

have you traced the line back into the inner workings of the quad to see where it attaches? i.e. master cylinder, brake reservoir, etc....?
