## Discrepancy

BRK FAIL YELLOW CAS: AFTER POWER UP WE DISCONNECTED THE GPU LIKE NORMAL AND RAN THE AFTER START CHECKLIST. WE RELEASED BRAKE TO TAXI FORWARD, AND MADE IT ABOUT 5 FT BEFORE THE BRAKE FAIL CAS ILLUMINATED. CONFIRMED NO PEDAL PRESSURE. WE THEN USED THE PARKING BRAKE TO STOP THE AIRCRAFT. CORRECTIVE ACTION: REPLACED BCM. OPS CHECK GOOD. IAW AMM 32-41-17.
