## Discrepancy

UPON TOUCHDOWN THE PILOT REPORTED NO BRAKES, CO-PILOT ALSO REPORTED NO BRAKES, ANTI-SKID WAS SELECTED OFF AND BRAKING WORKED. A TIRE WAS FLAT-SPOTTED AND THE OTHER DEFLATED, AND THE AIRCRAFT HAD TO BE TOWED FROM THE RUNWAY. AFTER WHEELS WERE REPLACED, AIRCRAFT WAS TAXIED WITH ANTI-SKID ON AND OFF AND THERE WERE NO ISSUES. ANTI-SKID WAS DEFERRED, AND AIRCRAFT FLOWN TO MAINTENANCE FACILITY WHERE ANTI-SKID FUNCTIONAL CHECKS WERE PERFORMED WITH NO FINDINGS.
