## Discrepancy

AFTER INSTALLATION OF THIS USED PART, ON LANDING FOLLOWING THE FIRST FLIGHT, THE PILOT DISCOVERED THAT HE HAD NO RIGHT BRAKE.  ON INSPECTION, IT WAS DISCOVERED THAT THE PISTON SHAFT HAD FRACTURED AT THE BASE OF THE THREADED PORTION WHERE THE FORK FOR ATTACHING THE PISTON SHAFT TO THE RUDDER PEDAL IS THREADED ONTO THE SHAFT.
