Booster Operation Inspection

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.
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 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.
