## Discrepancy

AFTER REPAIRS TO BELLY, LANDING GEAR, AND ENGINE, THE FIRST GROUND RUN WAS PERFORMED.  THE LEFT BRAKE LOCKED UP AND WOULD NOT RELEASE.  THE INVESTIGATION REVEALED THE PARK BRAKE RELEASED THE RIGHT BRAKE, BUT WOULD NOT FULLY RELEASE THE LEFT BRAKE.  THE REMEDY WAS TO SECURE THE PARK BRAKE CABLE END CLOSER TO THE BRAKE VALVE CONTROL ARM MAKING THE ACTUATION OF THE PARK BRAKE VALVE MUCH MORE POSITIVE ALL THE WAY TO THE STOPS.
