Went and looked at my brakes and found that Dexter had pre-wired the axle for electric brakes. When bought in bulk allows the manufacturer to wire down one side of the coach to the brakes, for electric brake system. We have the hydraulic disc brake system, and they work. Also found out the hard way that when the break away cable gets caught in the 5th wheel it pulled out and the system worked, the brakes locked.
Freightliner on the other hand wanted to go, soooooo we stopped
Good lesson!?
