## Discrepancy

ON FINAL APPROACH INTO CANADA WE HAD THE POWER BRAKE CIRCUIT BREAKER POP AND THE ANTI SKID INOP ANNUNCIATOR ILLUMINATE. WE WENT AROUND AND BROUGHT THE GEAR UP. FOLLOWED BY THE CHECKLIST.   WE RESET THE POWER BRAKE CIRCUIT BREAKER AND THE ANNUNCIATOR AND CAUTION WENT AWAY.  WE LANDED IN BUFFALO WITH THE CIRCUIT BREAKER STAYING IN AND BRAKES WORKING ON LANDING.  WE ELECTED TO GET TUGGED INTO THE FBO. CORRECTIVE ACTION: REPLACED POWER BRAKE RELAY 1AW CE560XL MM 24-50-03. REPAIRED INCORRECT SHIELD SPLICE IAW CESSNA SPM CHAPTER 20-30-25. ALL POST MAINTENANCE OPS CHECKS GOOD.
