Here is a good example of what can happen. See the photos at the bottom of this page:

"Normal brakes on a 747-300 are provided by system #4. Should system #4 be unable to supply pressure to the brakes, system #1 pressure may be used through a brake interconnect valve. The loss of system #4 pressure & system #1 pressure available -- automatically seclects the interconnect valve. There is a reserve brake system also. This reserve brake operates from system #2, but must be selected by the pilot.

At the time of this mess, the inboard engines, #2 & #3 were the only engines operating, & the reserve brake selection from #2 was not made. No hydraulic AC pump was selected "On" for number #4 system. No brake pressure was available because of this.

Also note that nose gear steering is only available from system 1#, so steering was not operable either."
