## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) THE FLIGHT INSTRUCTOR STATED THAT UPON LANDING HIS STUDENT INFORMED HIM THAT THERE WAS A PROBLEM WITH THE BRAKES. THE CFI TOOK THE CONTROLS AND CONFIRMED THAT THE RIGHT BRAKE WAS NOT OPERATING PROPERLY. THE CFI NOTIFIED THE TOWER OF A BRAKE FAILURE AT ABOUT MID-FIELD. HE ATTEMPTED TO STOP THE AIRPLANE ON THE RUNWAY, BUT UPON REALIZING THAT HE WAS APPROACHING THE END, HE BEGAN MAXIMUM BRAKING, WHICH RESULTED IN A WIDE ARCING TURN TO THE LEFT, EXITING THE RUNWAY AND STRIKING A PARKED CESSNA 210. THE CIRRUS SR-22 HAS A FREE CASTORING NOSE WHEEL, WHICH MAKES A BRAKE FAILURE NEARLY IMPOSSIBLE TO CONTROL ONCE THE AIRPLANE HAS SLOWED TO A SPEED BELOW WHICH AERODYNAMIC CONTROLS ARE FUNCTIONAL. THE RIGHT BRAKE CALIPER WAS INSPECTED AND FOUND TO BE COVERED WITH BRAKE FLUID. THE BRAKE PADS WERE REMOVED AND IT WAS NOTED THAT THE PADS WERE WORN DOWN TO THE RIVETS. THEY WERE ALSO WET WITH BRAKE FLUID. THE BRAKE CALIPER WAS DISASSEMBLED. THE HYDRAULIC PISTONS WERE REMOVED AND THE "O" RING SEALS WERE INSPECTED. THE "O" RINGS ON BOTH PISTONS WERE COMPLETELY FLAT. IT APPEARED THAT THE PISTONS WERE EXTENDING OUT TO THE ROUGH OUTER EDGE OF THE BRAKE CYLINDER, ALLOWING FLUID TO LEAK PAST THE SEAL.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
