A
757 MAINTENANCE MANUAL
(p) Make sure that the hydraulic systems are pressurized for the brake and nose wheel steering operations (Ref 29-11-00).
NOTE: Hydraulic power for the brakes comes from the right
____ hydraulic system. The left hydraulic system gives automatic backup when the right system does not operate. If the right and left systems do not operate, a reserve brake system can be started through the BRAKE SOURCE switch on the captain's instrument panel, P-1. If all hydraulic systems do not operate, the airplane must not be taxied. But, if all hydraulic systems stop during the taxi, the brakes will be operated through the brake hydraulic accumulator. The brake hydraulic accumulator is in the right hydraulic system.
When it is fully serviceable, the brake hydraulic accumulator will permit the brakes to be applied approximately 2 to 3 times.
The nose wheel steering gets power from the left hydraulic system. The landing-gear-control lever must be in the DN position to use the nose wheel steering system.
(q)
Make sure that the landing-gear-control lever is in the DN position.
(r)
Make sure that the VHF radio is on and set to the correct frequency. This is for radio communications with the authority for the airport ground control.
(s)
Make sure that the service interphone and the hand radios operate, and the ground crew can hear you.
