Start the engine, depress the brake pedal with approxi-
mately 500 N (110 Ibs.) of force, and measure the clearance
between the brake pedal and the floorboard.
Standard value(D): 80 mm (3.1 in.) or more
If the clearance is less than the standard value, check for
air trapped in the brake line and for brake fluid leaks. If
necessary, check the brake system mechanism (excessive
shoe clearance due to faulty auto adjuster) and repair
faulty parts as required.
models>
4. After adjusting the height of the brake pedal, inspect the shift lock device.
5. If there is any trouble in the functioning of the shift lock device, adjust the shift lock cable.
NOTE
Refer to GROUP 23 for details about inspection and
adjustment of the shift lock device.
BRAKE FLUID LEVEL SENSOR CHECKM35F6A6
(1) Connect a circuit tester to the brake fluid level sensor.
(2) Move the float from top to bottom and check for
continuity.
(3) The brake fluid level sensor is in good condition if there is
no continuity when the float surface is above “A”, and if
there is continuity when the float surface is below “A”.
BRAKE BOOSTER OPERATING INSPECTION MlKcAJ
For 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
(4
If
times with the same foot 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 condit’on. If there is no change, the booster is faulty.
.) 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.
the above three tests are okay, the booster performance
can be determined as gooa.
If one of the above three tests is not okay at last, the check
valve, vacuum hose, or booster will be faulty.

BLEEDING M35FYAM
Because the master cylinder employed is the type without the
check valve, air should be bled from the master cylinder by
following the procedures described below (if there is no brake
fluid in the master cylinder).
(1) Disconnect the brake tube from the master cylinder.
(2) Two persons’ should conduct the air bleeding, one person
slowly depressing the brake pedal and holding the pedal
depressed.
(3) In this condition, the other person should use a finger to close the outlet part of the master cylinder, and then the
first person should release the brake pedal.
(4) Steps (2) and (3) should be repeated three or four times, and then the master cylinder should be filled with brake
fluid to the specified level.
I(]OTE
The air is completely bled from the master cylinder by
steps (1) to (4).
(5) Connect the brake tube to the master cylinder.
(6) Start the engine; then, in the sequence shown in the illustration, bleed the air from each wheel cylinder, delay
valve and hydraulic unit.
Specified brake fluid: Confoming to DOT3 or DOT4
Caution
1.Use the specified brake fluid. Avoid using a mixture
of the specified brake fluid and other fluid.
2. If brake fluid is exposed to the air, it will absorb moisture; as water is absorbed from the atmo-
sphere, the boiling point of the brake fluid will
decrease and the braking performance will be
seriously impaired. For this reason, use a hermeti-
cally sealed 1 dms (1.06 qt.) or 0.5 dms (0.52 qt.)
brake fluid container.
3. Firmly close the cap of the brake fluid container
after use.
4. For vehicles with the anti-lock braking system, be
sure to install a filter to the master cylinder
reservoir tank when supplying brake fluid.
NOTE
For FWD-vehicles with the anti-lock braking system, the
brake pedal will have a “heavier” feeling for air bleeding of
the rear brakes than for the front brakes, but this is the
result of the constriction of fluid pressure within the delay
valve, and is not a malfunction.

A.B.S. POWER RELAY CHECK
M3EFOAQ
(1) Remove the A.‘B.S. power relay from the left cowl side
trim.
16LO312wveoa
(2) Connect battery to terminal 2 and check continuity
between terminals with terminal 4 grounded.
DELAY VALVE CHECK
models>
M35FOAE
In the same way as for other hydraulic circuits, the delay valve
has little effect upon the operation of the A.B.S. unless dirt,
etc. get into the oil passage and clog it. Moreover, there are
almost no malfunctions other than clogging.
Consequently,
9 gauge is not used when checking the delay
valve; a simple check is made as described below.
1)Loosen the bleeder for air beeding
of the rear brakes, and
then remove the brake fluid by following the method used
for air bleeding. (Do this for the left and right wheels.)
2) If, after the brake fluid is removed, the force required to depress the brake pedal is more than that required for
vehicles with ordinary brakes, the condition is normal.
3)If the brake fluid doesn’t come out, remove the delay valve
and check for clogging. If brake fluid comes out but the
brake pedal depressing force doesn’t feel “heavy”, the
delay valve is malfunctioning and must be replaced.

(2) The vacuum hose at the engine should be securely
connected until it contacts the hexagonal edge of the
fitting, and then should be secured by the hose clip.
4. CONNECTION OF VACUUM HOSE (1) The vacuum hose at the brake booster should be connected for the distance shown in the illustration,
and should be secured by
the.hose clip so that there is
no contact with the check valve.
(2) The vacuum hose at the engine should be securel
