## Discrepancy

THE RT BRAKE CALIPER UPPER ANCHOR BOLT SHEARED DURING BRAKING ACTION ON LANDING.  THIS ALLOWED THE BRAKE CALIPER TO ROTATE AFT ABOUT THE AXIS OF THE LOWER ANCHOR BOLT & CONTACT THE INSIDE SIDEWALL OF THE MLG TIRE.  APPLICATION OF RT BRAKE HAD NO AFFECT DUE TO THE PISTON PUSHING OUT OF THE CALIPER HOUSING LOOSING PRESS & HYD FLUID.  THE ANCHOR BOLT SHEARED IN THE THREADED AREA ADJACENT TO THE NUT.  HE REMAINING STUD MOVED OUTWARD THROUGH THE TORQUE PLATE & CONTACTED THE MAIN WHEEL TIE BOLTS DAMAGING THE HEADS OF BOLTS
