4. Bleed the brake line and the
SSTs
of air. Bleed the air form the SSTs using bleeder screw A.
5. Install the pedal force gauge to the brake pedal.
6. Connect the vacuum gauge to the vacuum line.

Vacuum loss inspection
1. Start the engine.
2. Depress the brake pedal with a force of
200 N {20.4 kgf, 44.9 lbf}.
3. Stop the engine when the vacuum gauge reading reaches
68 kPa {510 mmHg, 20.1 inHg}
with the pedal
depressed.
4. With the engine off, observe the vacuum gauge for
15 s.
5. If the gauge has dropped
3.3 kPa {25 mmHg, 1.0 inHg}
or less, the unit is normal.
Lack of hydraulic pressure inspection
1. If the pedal force and fluid pressure correlation is within the specification with the engine stopped and a
vacuum amount of
0 kPa {0 mmHg, 0 inHg},
the system is normal.

Hydraulic pressure inspection
1. Start the engine. Depress the brake pedal when the vacuum reaches 66.7 kPa {500 mmHg, 19.7 inHg}.
2. At this time, apply the indicated pedal force and if the fluid pressure is within the specification, the unit is
normal.
