"Anyone that descends mountain passes on services brakes only in just asking for trouble! Chris" Hey bucko, what makes you think I do? I have an ebrake and I use it right so I don't have to use the brakes. Two times I've had pinched wire problems and as luck would have it, the blue and red wires were getting the insulation split and bumping the conductors together. Both times, I was cruising down the road, not touching the brakes at all. Both times, it was only intermittent and light pulsing and it only took 5-6 miles to melt the lining. Both times, it felt like engine miss firing and I was worried about the truck conking out and then I saw the smoke... too late. Craig
