A CE560 WAS OPERATED AFTER L AND R MAIN GEAR BRAKES WERE REPLACED; BUT WITH NO 'BURN IN' PROC ACCOMPLISHED. FLT CREW CONCERNED PROC NOT ACCOMPLISHED.

Narrative

DURING PREFLT NOTICED THAT PREVIOUS CREW HAD WRITTEN UP BRAKES BEING SPONGY. CORRECTIVE ACTION STATED THEY 'FOUND BRAKE PUCKS TO BE LEAKING' AND REMOVED AND REPLACED 'BRAKES #1 AND #2.' FLEW 2 LEGS; THEN IT OCCURRED TO ME THAT THE ACTUAL BRAKE PADS LOOKED NEW; NOT JUST THE BRAKE ASSEMBLIES THAT I ASSUMED WERE REPLACED PER THE CORRECTIVE ACTION. NORMAL PROC IS TO ACCOMPLISH A BRAKE BURN-IN PRIOR TO FLT WHENEVER NEW PADS ARE INSTALLED. I CONTACTED OUR MAINT CTL CTR AND DISCOVERED THAT THE PADS WERE INDEED NEW; AND THAT A MISTAKE WAS MADE WHEN THEY RELEASED THE ACFT FOR FLT WITHOUT A BURN-IN. THEY FURTHER STATED; AFTER REFING THE MAINT MANUAL; THAT IT WAS OKAY TO ACCOMPLISH IT AFTER THE 2 LNDGS WHICH I ALREADY DID. THE DIRECTOR OF MAINT AND THE CHIEF PLT BOTH APPROVED THIS. I'M NOT SURE IF A MAINT REG WAS VIOLATED; AS THE MAINT MANUAL DOES NOT SAY THE BURN-IN IS REQUIRED; BUT I THOUGHT IT BEST TO RPT IT; ON THE RECOMMENDATION OF OUR UNION REPRESENTATIVE. THIS WAS CAUGHT BY USING COMMON SENSE AND DISCUSSION BTWN MYSELF AND MY FO; AND WAS CAUSED BY A POORLY-WORDED MAINT WRITE-UP.
