4A-11 Brake Control System and Diagnosis:
3) Depress brake pedal several times with the same
load as in ordinary braking and observe pedal travel.
If pedal goes down deep the first time but its travel
decreases as it is depressed the second and more
times, air tightness is obtained.
[A]: Good
1. 1st
4) If pedal travel doesn't change, air tightness isn't
obtained.
NOTE
If defective, inspect vacuum lines and sealing
parts, and replace any faulty part.
When this has been done, repeat the entire
test.

Check operation
1) With engine stopped, depress brake pedal several
times with the same load and make sure that pedal
travel doesn't change.
2) Start engine while depressing brake pedal. If pedal
travel increases a little, operation is satisfactory. But
no change in pedal travel indicates malfunction.
Check air tightness under load
1) With engine running, depress brake pedal. Then
stop engine while holding brake pedal depressed.
