When disconnecting vacuum hoses, attach a tag
describing the correct installation positions so that the
hoses can be reinstalled correctly.
After servicing fuel, oil, coolant, vacuum, exhaust or
brake systems, check all lines related to the system for
leaks.
For vehicles equipped with fuel injection systems, never
disconnect the fuel line between the fuel pump and
injector without first releasing the fuel pressure, or fuel
can be sprayed out under pressure.
When performing a work that produces a heat exceeding
80°C (176°F) in the vicinity of the electrical parts, remove
the heat sensitive electrical part(s) beforehand.
Use care not to expose connectors and electrical parts
to water which will be a cause of a trouble.
Always be careful not to handle electrical parts (com-
puter, relay, etc.) in a rough manner or drop them.

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.
4) If pedal travel doesn’t change, air tightness isn’t obtained.
CHECK OPERATION
1) With engine stopped, depress brake pedal several times with
the same load and make sure that pedal travel doesn’t
change.
2) Start engine while depressing brake pedal. If pedal travel
increases a little, operation is satisfactory. But no change in
pedal travel indicates malfunction.

the entire test.
