B66:
Does your question hint at whether the park brake needs to be set after an RTO? T
There is always a debate about whether to set the park brake after a high speed RTO in case of brake seizure. All airlines I have worked for had an SOP of "set park brake and analyse." In doing so you will apply pedal pressure and so disarm the autobrakes.
Some airlines retract the spoilers with a/c stopped, others do only if an evac is required. The former would disarm the autobrakes.
