BOOSTER OPERATION CHECK

There are two ways to perform this inspection, with and without a
tester. Ordinarily, it is possible to roughly determine its condition
without using a tester.
NOTE:
For this check, make sure that no air is in hydraulic line.
INSPECTION (WITHOUT TESTER)
Check Air Tightness
1) Start engine.
2) Stop engine after running for 1 to 2 minutes.
3) Depress brake pedal several times with the same load as in or-
dinary braking and observe pedal travel. If pedal goes down
deep at the first time but its travel decreases as it is depressed
the second and more times, air tightness is obtained.
4) If pedal travel doesn't change, air tightness isn't obtained.
NOTE:
If defective, inspect vacuum lines and sealing parts, and re-
place 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.
