Caution
If the number of brake lever notches engaged is less
than the standard value, the cable has been pulledexcessively, and failure of the automatic adjuster
mechanism will result. Be sure tti adjust it to within the
standard value.(6) After making the adjustment, check to be sure that there is
no play between the adjusting nut and the pin. Also check
to be sure that the adjusting nut is securely held at the nut
holder.(7) After adjusting the lever stroke, jack up the rear of the
vehicle.(8) With the parking brake lever in the released position, turn
the rear wheel to confirm that the rear brakes are not
dragging.
PARKING BRAKE SWITCH CHECKN05FDAB
(1) Disconnect the connector of the parking brake switch, and
connect an ohmmeter to the parking brake switch and the
switch installation bolt.
(2) The parking brake switch is good if there is continuity whenthe parking brake lever is pulled and there is no continuity
when it is returned.
BRAKE BOOSTER OPERATING
lNSPECTIONNoSFcuFor simple checking of brake booster operation, carry out the
following tests.
(1) Run the engine for one or two minutes, and then stop it.
(2) Step on the brake pedal several times with normal
pressure.If the pedal depressed fully the first time. but gradually
becomes higher when depressed succeeding times, the
booster is operating properly.
If the pedal height remains unchanged, the booster is
faulty.(3) With the engine stopped, step on the brake pedal several
times with the same pressure to make sure that the pedal
height will not change.
Then step on the brake pedal and start the engine.
If the pedal moves downward slightly, the booster is in
good condition. If there is no change, the booster is faulty.
(4) With the engine running, step on the brake pedal and then
stop the engine.
Hold the pedal depressed for 30 seconds. If the pedal
height does not change, the booster is in good condition.
If the pedal rises, the booster is faulty.
If the above three tests are okay, the booster performance canbe determined as good.
If one of the above three tests is not okay at last, the check
valve, vacuum hose, or booster will be faulty.

9.Check whether or not the change in the fluid level is within5 mm
(.2 in.) when the engine is stopped and when it is
running.
Caution
1.If the change of the fluid level is 5 mm I.2 in.) or more,
the air has not been completely bled from the system,
and thus must be bled completely.2. If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled.
3. If air bleeding is not complete, there will be abnormal
noises from the pump and the flow-control valve, and
this
condition could cause a lessening of the life of the
