## Discrepancy

RIGHT BRAKE WHEN APPLIED WILL RAPIDLY INCREASE & DECREASE BRAKE PRESSURE CAUSING A VERY JOLTY TAXI. IT IS ESPECIALLY PROMINENT WHEN LIGHT PRESSURE IS ADDED AT LOW TAXI SPEEDS.  DOWNLOADED FDR DATA FOR THEM TO REVIEW. BLED BOTH MLG BRAKES & PARKING, EMERGENCY BRAKES & NOTED SOME AIR WHILE BLEEDING THE RT BRAKE. SERVICED THE HYD RESERVOIR AS NEEDED. PERFORMED A TAXI CHECK WITH MULTIPLE BRAKE CHECKS AT IDLE SPEED AS WELL AS 25-30KTS,  ABLE TO SLOW & STOP THE ACFT SMOOTHLY WITHOUT ANY PULL OR SHUDDERING.  RETURNED ACFT TO ITS ORIGINAL CONFIGURATION. WORK PERFORMED IAW AMM 32-40-00.
