## Discrepancy

WHEN BRAKING AFTER LANDING THERE IS A LOUD CHATTERING FROM THE  BRAKES AND A VERY NOTICABLE VIBRATION AND SHUDDERIG THAT ACCOMPANIES RHE NOISE. WE CAN NOT TELL WHICH MAIN BRAKE IS CAUSING THE PROBLEM.  BLED BRAKES AND FOUND A GOOD AMOUNT OF AIR IN THE SYSTEM. TECHS PERFORMED ENGINE RUN AND TAXI FOR OPERATIONAL CHECKS AND LEAK CHECKS. ALL CHECKED GOOD. ALL WORK COMPLETED IAW CE680A AMM 32-42-00 AND 71-00-00
