Hoses, lines/piping, and fittings (service brakes)
The front hoses on the involved vehicles may have improperly oriented hose fittings, resulting in a rubbing contact between the right brake hose and the upper control arm of the front suspension or in a twisted left hose resulting in a faulty attachment at the frame fitting. Should either of these conditions exist, they could eventually…
Remedy: The dealer will inspect and, if necessary, replace one or both front brake hoses at no cost to owner.
