Autobrake – Disarm
The pilots may disarm the autobrake system by moving the selector switch to the
OFF position. This action does not cause the AUTO BRAKE DISARM light to
illuminate. After braking has started, any of the following pilot actions disarm the
system immediately and illuminate the AUTO BRAKE DISARM light:
• moving the SPEED BRAKE lever to the down detent
• advancing the forward thrust lever(s), except during the first 3 seconds
after touchdown for landing
• applying manual brakes.
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 CONFIG lights illuminate and the takeoff configuration warning
horn sounds if either forward thrust lever is advanced for takeoff with the parking
brake set.
Brake Temperature Monitoring System
1B785, 1J585 - 1J594
(as installed)
The temperatures of each main landing gear (MLG) brake are displayed on the
MDS System page. If any of the brake temperatures correspond with an
overheated brake, the temperature value for that brake as well as the associated
brake symbol turn amber, and the BRAKE TEMP light on the forward electronic
panel illuminates.
