If A320's have a history of sticking brakes AFTER setting the parking brake that would be a reasonable technique to pass on.
We don't know from the OP if he's on the A320. I've flown 8 major airliners(no A320) and stuck brakes has never been an issue.
We're faced with a constant battle in aviation about old technology/techniques vs. new technology/techniques. Do the old tricks still apply to the new situation? That's the endless battle and can result in guys trying to bring something from the past into the present. Sometimes their advice should be heeded and sometimes it should be discarded.
For example - raw data backup? Absolutely...until we got GPS's!
And 'Ace the Techincal Interview' says that GPS's aren't as reliable(2002 printing).
Recently NATS flight showed us 0.06 off in the middle of the N. Atlantic.
Literally had a FO try to fly a 6 hr flight in an FMC a/c using raw data and heading select. Why? Because he didn't trust the LNAV/VNAV.
So does the particular tail number, of model(A320, or early A320), have a history of stuck brakes? That would warrant some caution. If it doesn't I personally wouldn't worry about it.
