## Discrepancy

ONLY RH BRAKE CAUSED IT, TESTED THEM INDEPENDENTLY AND ONLY FELT THE SHAKE,SHUDDER WHEN RT BRAKING WAS APPLIED.  REMOVED FAULTY RT MLG BRAKE ASSEMBLY & INSTALLED A CUSTOMER SUPPLIED OVERHAULED BRAKE ASSEMBLY. PERFORMED SATISFACTORY BLEED/OPS CHECKS WITH NO DEFECTS. ALL WORK PERFORMED IN REF WITH  AMM 32-45-21
