## Discrepancy

(CAN) WHILE CHANGING THE RT MAIN TIRE, THE OUTBOARD DISK WAS FOUND CRACKED. SINCE THE BRAKE WEAR INDICATORS WERE FAR FROM THEIR MAXIMUM LIFE INDICATION, THIS COULD BE CONSIDERED PREMATURE FAILURE. NOTE:THERE HAD BEEN A NOISE COMING FROM THE BRAKE DURING TOWING. THE BRAKE UNIT HAD BEEN INSPECTED WITH THE WHEEL OFF, BUT NO DEFECTS HAD BEEN NOTED. ONLY FULL DISASSEMBLY OF THE BRAKE UNIT ITSELF MAY HAVE FOUND THE CRACKS EARLIER.  BRAKE UNIT WAS REPLACED WITH A SERVICEABLE UNIT
