I do not believe that the fligth computer will release any brakes.
Firstly that might be very dangerous in specific situations and secondly
there where two incidents recently that shows us that it cannot be true:
1. Some months ago a A319 or A320 landed with the parking break set.
The outcome where a hard nosewheel touchdown, blown tires and control
problems. The report is available on the internet (I suppose it happened in
the UK).
2. The Iberia A340-600 Crash landing in Ecuador: Due to a very hard
touchdown they lost the Air/Ground logic. That left them with no Groundspoilers,
no Reversers but WITH THE Brakes. - And that also was an A340-600.
