Quick Inspection (On-vehicle)
Power brake unit function check
(Method-using tester)
Connect the SST, vacuum gauge A, and pedal depression
force gauge B as shown in the figure. After bleeding the
air from the SST, conduct the test as described in the 3steps
below.
Note l
Use commercMty available vacuum gauge and ped.
al depression force gauge.
a) Checking for vacuum loss
Unloaded condition
1. Start the engine.
2. Stop the engine when the vacuum gauge reading reaches
66.7 kPa (500 mmHg, 19.7 inHg ) .
3. Observe the vacuum gauge for 15 seconds. If the gauge
shows 63.3-66.7 kPa [475--500 mmHg, 18.7-19.7
inHg 1, the unit is operating.
Loaded condition
1. Start the engine.
2. Depress the brake pedal with a fdrrce of 196 N I20 kgf,
44 Ibfj.
3. With the brake pedal depressed, stop the engine when the
vacuum gauge reading reaches 66.7 kPa {SO0 mmlig,
19.7 inHg].
4. Observe the vacuum gauge for 15 seconds. If the gauge
shows 63.3-66.7 kPa I475--500 mmHg; 18.7-l 9.7
inHg 1, the unit is operating.
b) Checking for hydraulic pressure
1, If with the engine stopped (vacuum 0 kPa (0 mmHg, 0
hltlg 1) the fluid pressure is within specification, the unit is
operating.

2, Start the engine. Depress the brake pedal when.the vacu-
urn reaches 66.7 kPa 1500 mmHg, 19.7 intlg 1. If the flu-
id pressure is within specification, the unit is operating.

2. Bleed the air from the brake system.
3. Depress the brake pedal until the master cylinder pressure
equals A; then record rear brake pressure A’.
4. Depress the brake pedal again, apply additional pressure
until the pressure equals B; then record pressure B’.
