## Discrepancy

INVESTIGATION REVEALED PRIMARY CAUSE WAS PISTON HAD EXTENDED TOO FAR FROM BRAKE CYLINDER AND HAD JAMMED IN APPLIED POSITION DUE TO EXCESSIVELY WORN LININGS AND UNAPPROVED SHIM BETWEEN BRAKE CYLINDER AND BRAKE BACKING PLATES.  BACKING PLATES AND CYLINDERS ALSO SHOWED EVIDENCE OF DAMAGE DUE TO BACK PLATE ATTACH BOLT ATTACH BOLTS BEING CONSISTENTLY OVERTORQUED.
