## Discrepancy

THE LT BRAKE FAILED ON TAXI OUT.  BRAKE PEDAL WAS FIRM BUT BRAKE WAS STILL INOPERATIVE.  BRAKE RESERVOIR IS FULL & ALL BRAKE ACCUMULATORS ARE IN LIMITS.  ALSO THERE WERE NO BRAKE SYS BITE INDICATORS SHOWING FLAGGED.   INSPECTED LT BRAKE ASSEMBLY & BRAKE WEAR PINS, NO DEFECTS NOTED.  GAINED ACCESS TO BOTH CREWMEMBERS MASTER CYLINDERS & INSPECTED FOR LEAKS OR DAMAGE, NONE FOUND.  PRIMED & BLED LT MASTER CYLINDER & ALSO BLED LT BRAKE SYS.  USED SHOP BRAKE BLEEDING FIXTURE, SERVICED SYS 1 QT. OF SKYDROL 500B SINCE RESERVOIR SHOWED LOWER AMOUNT ON BRAKE RESERVOIR.  INSPECTED BLEED VLV, HYD PACK ASSEMBLY SUCTION LINE & LT NOSE COMPARTMENT FOR LEAKS NO DEFECTS NOTED.  ALL WORK DONE IAW AMM 32-42-00.  OPERATIONS CHECKED GOOD.  TAXI CHECKED GOOD.
