## Discrepancy

PILOT REPORTED RT BRAKE DE-ICE DOES NOT ILLUMINATE ON CYCLE AFTER LANDING OR BEFORE TAKEOFF.  REPLACED VALVE ASSEMBLY. SUBMITTER STATED THESE PARTICULAR VALVES HAVE A VERY POOR RELIABILITY FACTOR.  THEY ARE NOT RELIABLE AND USUALLY ONLY LAST ABOUT 6 MONTHS UNTIL THEY FAIL.  THIS VALVE HAD 312.6 HOURS AND 372 CYCLES.  RECOMMEND MANUFACTURER LOOK FOR THE PROBLEM AND IMPROVE RELIABILITY.
