Best Technique for Brake Check on the A321
This has been a point of different views when it comes to checking brakes at the commencement of the Taxi-out phase of a flight.
On the A321 ( 320 Family) releasing the Parking Brake disconnects the Yellow Hyd Braking system and transfers braking to the Green Hyd system.
Is it better to release brakes let the A/C roll then smoothly apply brakes again.
Or by simply releasing brakes while holding the brake pedals for a brief period insures that the green hyd braking system is functional.

Whichever way you choose to do it is fine as long as it doesn't involve slamming on the brakes and grinding to a near-halt with the poor cabin crew thinking we've it a brick wall as some I have witnessed.
Sooner rather than later after starting to taxi, gently press the brakes, see/feel evidence of retardation then release
