TRAVELING AT 65 MPH BRAKES ALL OF A SUDDEN THE BRAKES WERE APPLIED W/O APPLYING THEM LOSS OF STEERING CONTROL ETC. EVALUATING THIS PROBLEM II SAW THAT THE BRAKE PEDAL WAS GOING DOWN TO THE FLOOR, SO I PULLED UP ON IT WITH MY FOOT AND THE BRAKES RELEASED BUT STEERING CONTROL DID NOT RESUME. I GOT OFF AT THE NEXT EXIT AND VERY SLOWLY MADE MY WAY ON HOME. ANY APPLICATION OF THE BRAKE PEDAL RESULTED IN BRAKES LOCKING UP AND THEY WERE APPLIED SO TIGHTLY THAT ANY ACCELERATION COULD NOT SPEED UP UNLESS I PULLED UP ON THE BRAKE PEDAL. UPON ARRIVING HOME LOOKED THINGS OVER NO POWER STEERING UNLESS MOTOR WAS AT HIGH RPM,POWER STEERING PUMP LOOKED AS IF IT EXPELLED FLUID OUT THE BREATHER CAP AND THE BRAKES SMELLED AS IF VERY HOT. NOW THAT THIS HAPPENED I RECOGNIZED THIS HAD HAPPENED BEFORE BUT SOMEHOW REPAIRED ITSELF,BUT NOT TO THIS EXTREME. I SUFFERED BRUISES FROM SHOULDER HARNESS AND SEATBELT AND SOME KNOTS ON MY HEAD FROM BEING THROWN AROUND I CAME SO CLOSE TO OUT OF CONTROL AND A ROLLOVER SIMPLY COULDN'T CONTROL MY TRUCK. *TR
