How you brake will depend on a number of factors - to my mind, a better wording to this particular braking option would be along the lines of .... "commence braking as appropriate for aircraft systems and the operational requirements".

Multiple brake systems/antiskid/auto-brake will all impact exactly how you brake. Also - Operational requirement - runway length, surface, condition, contamination .... all impact braking. Your operations manual will probably be quite specific on braking in contaminated conditions - which auto-brake setting and so on ...

So, how do we answer the question ..... the current Exam wording (I think) is:

BRAKE VERY HARD ...... NO, we won't (it’s poor wording)

Another wording that has been around:

WAIT UNTIL BELOW HYDROPLANE SPEED FOR BRAKING ..... again, NO.
