You need to dive into this much further...once the ac bounced, you had weight on wheels, and the ac is now in land mode, thus shutting off many systems...that being said.
Speed brakes and spoilers are secondary systems, but in land mode, extend full to optimize braking...thus in the balked landing you describe, the ac is in land mode.
