Don't use graphite lube. Graphite and Aluminum don't get along. The brake castings are Aluminum (as well as the primary structure of the rest of the airplane).
That's why many shops don't allow pencils in their shops or at a minimum in the sheet metal areas. If someone were to make a pencil line on an Aluminum sheet the grarphite could etch away the aluminum over the years resulting in a detectible score line or even a crack. Every military spec for dry film lubricants prohibits the use of graphite. Imagine being an aircraft structural design engineer tasked with assembling graphite carbon fiber wings or tail to an aluminum fuselage. Not only do the materials hate each other (opposite ends of the galvanic chart) but one has a positive coefficient of resistivity and the other a negative coefficient of resistivity. And one shrinks and swells with temperature while the other stays stiff and firm. One flight from a hot tropical airport to 30,000 feet with lightning about makes all-metal aircraft look wonderful.
Back to the brakes. Instead of graphite dry lube consider a Teflon or silicon dry lube. Like PB Blaster TFE, Dry film lube Silicon or even my current favorite, NanoPro M/T military-spec grade dry lube based on nano technology - - available at Autozone.
