it. If the pedal depresses fully the first time but grad-
ually becomes higher when depressed succeeding
times, the booster is operating properly, if the pedal
height remains unchanged, thebooster is inoperative.

good condition. If there is no change, the booster is
inoperative.

3.
With the engine running, step on the brake pedal and
then stop the engine.
Hold the pedal depressed for 30 seconds. If the pedal
height does not change, the booster is in good condi-
tion, if the pedal rises, the booster is inoperative.
If the above three tests are okay, the booster perfor-
mance can be determined as good.
Even if one of the above three tests is not okay, check
the check valve, vacuum hose and booster for mal-
function.
