Release brake,直译就是释放刹车，更直观的翻译是松开刹车，一样的意思

Parking Brake set to OFF
When the selector switch is set to OFF, the motors in the control valve 4GZ are energized again (in the opposite direction). The control valve operates, which:
-    isolates the hydraulic power supply from the brakes
-    connects the parking braking system to return
-    releases the control pressures at the automatic selector valve 5202GG and the park brake operated valve 5801GG.
When the pressure is released from:
-    the automatic selector valve 5202GG, it connects the Alternate servo valves to return
-    the park brake operated valve 5404GG, it connects the dual valve 5403GG to the Alternate braking system
-    the dual shuttle valve 5404GG, it closes the supply line from the control valve 4GZ and opens the supply lines from the dual valve 5403GG
