NOTE: Push the pedals to the stops in 1 second, hold in for
____ 1 second, and release in 1 second. Wait 5 seconds seconds between each time that you push in and release the brake pedals.
(c) Make sure that the BRAKE PRESS gage indication is at least 1200 psig.

Do a test of the Alternate System Braking
(a)
Push in and release brake pedals a minimum of 6 times until the pressure shows on the BRAKE PRESS gage does not decrease any more with brake pedal operation.
(b)
Pressurize the left hydraulic system and reservoir (AMM 29-11-00/201).
(c)
Measure the brake pedal force and travel for each brake pedal. Make sure that each pedal meets the requirements in Table 3. 1) Attach a protractor to the brake pedal to measure the
travel.
2) Attach a spring scale to the brake pedal to measure the
pedal force. ~.............................................................................. | Table 3 | ................................................................................ | *[1] | *[2] | ................................................................................ | | Brake Pedal | Brake Pedal | Brake | Brake Pedal | | Pedals | Travel (DEG) | Force (LBS) |Pressure (PSIG) | Force (LBS) | ................................................................................ |Captain's, | | | | | |First Officer's | 5 Maximum | 29 (|3) | 500 (|50) | 43.6 (|4.6) | ................................................................................ |Captain's, | | | | | |First Officer's | 12 Maximum | 64 (|4) | 2800 (|50) | 96 (|6) | 2................…..............….............…................…...............1
*[1] The pedal force must be measured by the load applied
perpendicular to the tip of the pedal, 8.4 inches from the pivot.
The brake pressure is the value shown at each wheel brake gage.
*[2] The brake pedal force measured using the J32001-39 equipment. The
load on the J32001 is located 5.58 inches from the pedal pivot.
(d)
Make sure that the pressure indication at each wheel brake is not more than 75 psig after you release the brake.
(e)
Push in and hold the Captain's brake pedals against the stops.

(f)
Make sure that the brake pressure shown at each wheel brake gage is within 200 psig of the system supplied pressure (2850 to 3150 psig).
(g)
Look at the wear indicator pin on each brake to make sure that each brake has set.
(h)
Release the brake pedals.
(i)
Make sure that the pressure at each brake is not more than 75 psig.
(j)
Look at the wear indicator pin on each brake to make sure that each brake has released correctly.
(k)
Repeat steps (d) thru (i) with the First Officer's brake pedals.

(15)
Continue the test.
(a)
Push the manual override button on the landing gear control panel and move the landing gear control handle to the UP position.
(b)
Make sure that the pressure at each wheel brake gage is 450 to 880 psig.
(c)
Move the landing gear control handle to the DN position.
