Narrative:

During landing roll. Brake effectiveness on the right side was slightly less than normal. A post flight inspection revealed that the right inboard brake was cold to the touch. The right inboard brake temperature monitoring system (btms) only registered 01 and the right outboard registered significantly higher at 07. An [aircraft maintenance log] entry was made. The corrective action was to ops check brake movement and check the maintenance diagnostics computer (mdc). According to the mechanic who was referring to the aircraft maintenance manual (amm); the mdc did not have an anti-skid malfunction that was recent enough to dictate troubleshooting the anti-skid system. The [aircraft maintenance log] only went back a few weeks so the only history on this was my write up; one a few pages before that and another [8 days ago]. I have observed other aircraft with this malfunction where the history goes back much further.there is not enough data available for me to know how long the history is for this brake malfunction. I fear this aircraft still has an inoperative brake and as of yet there is not sufficient procedures in our pilot and maintenance manuals for proper identification and correction of these defects. Aircraft controllability during this malfunction is not much of a factor. The asymmetry is almost unnoticeable; which is why the last report I filed had a long history of operations with this latent defect. What is significant though; is that takeoff and landing (tol) data is based on all brakes operating; so every aircraft that has this latent defect is operating with invalid tol data every flight.this is the third aircraft I have seen this problem on and I will continue to report others I encounter. I will also encourage others to do the same. I would appreciate it if publications were updated to ensure that I don't see this problem being misdiagnosed.
