Narrative:

Air carrier maintenance bled left brake in ZZZ due to write-up for brake grabbing. I noticed slightly heavy brake application necessary during taxi out, but did not suspect a mechanical problem. Upon landing mia, aircraft yawed to right upon brake application, and then I discovered no brakes at all on the left gear. I now suspect brakes were not working after the repair in ZZZ and went undetected until landing. Next time I taxi our after brake work, I will check braking on each side independently. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a B727-200 and had the left brakes bled before departure. The reporter said on arrival at mia the left brakes did not operate. The reporter said the left brake lockout cylinder was not resvced into the green band after bleeding. Callback conversation with reporter acn 436005 revealed the following information: the reporter stated after the brakes were bled no visible brake leakage was noted and the condition of the lockout cylinder was not noted. The reporter said it is possible the aircraft was dispatched with the left brake lockout cylinder depleted.
