Parking Brake
The parking brake can be set with either A or B hydraulic systems pressurized. If
A and B hydraulic systems are not pressurized, parking brake pressure is
maintained by the brake accumulator. Accumulator pressure is shown on the
HYD BRAKE PRESS indicator.
The parking brake is set by depressing both brake pedals fully, while
simultaneously pulling the PARKING BRAKE lever up. This mechanically
latches the pedals in the depressed position and commands the parking brake
valve to close.
The parking brake is released by depressing the pedals until the PARKING
BRAKE lever releases. A fault in the parking brake system may cause the
ANTISKID INOP light to illuminate.
The takeoff configuration warning horn sounds if either forward thrust lever is
advanced for takeoff with the parking brake set.
