Abs valve body / pump harness chafed through brake hydraulic line near transmission crossmember. This resulted in a hydraulic leak and loss of brake pedal feel / partial loss of brakes. Fortunately failure occurred in the driveway--I had 4500 lbs of sailboat trailer hitched to the van and was about to go on a long trip. Design issue. Wiring harness should not be located so as to chafe on hydraulic lines. This is not the first chafe related failure on this vehicle.
Violent shaking while applying brakes.
