MECHANICAL BRAKE FAILURE RESULTING FROM AN ENGINE STALL CAUSED THE 966C FRONT-END LOADER TO ROLL BACKWARDS DOWN THE STOCKPILE RAMP INTO THE VICTIM AND HIS 2001 DODGE PICK-UP. THIS CAUSED THE V ICTIM TO BE CAUGHT BETWEEN THE TWO VEHICLES RESULTING IN FATAL INTERNAL INJURIES. OUR INVESTIGATION IS STILL PENDING ON WHAT CAUSED ANY BRAKE FAILURE.
