From FCOM:
The basic AUTO BRK disarms or deactivates when:
‐ The flight crew applies sufficient pedal deflection on one or both brake pedals, or
‐ The aircraft is in flight for more than 10 s (for RTO mode only), or
‐ The flight crew sets the AUTO BRK Mode selector to DISARM, or
‐ The flight crew presses the RTO pb in order to turn off the RTO light, or
‐ The flight crew presses one of the A/THR instinctive disconnect pushbuttons (only with basic AUTO BRK LDG modes, not for RTO mode), or
‐ Any basic AUTO BRK arming condition is lost, or
‐ The ground spoilers retract.
