## Discrepancy

DURING A NORMAL BRAKE CHANGE, A PROBLEM WAS ENCOUNTERED.  A SEARCH FOR REPLACEMENT BRAKES WAS INDICATED USING THE ABS P/N.  DURING THE COURSE OF THE SEARCH, A GULFSTREAM P/N WAS GENERATED.  IT WAS ONLY AFTER THE FACT DISCOVERED THE GULFSTREAM P/N WAS INCORRECT.  THIS RESULTED IN THE INSTALLATION OF A 15 DEGREE SLOTTED BRAKE WITH A ZERO DEGREE KEYED WHEEL.  DAMAGE TO THE BRAKES HAS OCCURRED AND POSSIBLY THE WHEELS.  ALL FOUR WHEELS AND BRAKES WILL BE CHANGED W ITH SERVICEABLE UNITS.  CAUSE:  INCORRECT P/N BRAKES INSTALLED DUE TO WRONG P/N BEING REQUESTED.  (X)
