Not today. give me some time for the medicines to take a hold. Maybe I can get warped enough to understand this.... and I thought I was bad myself.
I simply do not understand what that particular complaint is all about. To me a airbrake system on a tractor and trailer are pretty specific. But when written like that? I cannot begin to comprehend enough and would not help anyone by trying to untie this... this... gordion knot.GrapeApe Thanks this. -

Anybody ever heard of a Volvo truck not wanting to stop when brakes are pressed. The truck continues to power forward and then suddenly snatches to a dead stop.
