7) Check the pedal stroke.
While the engine is idling, depress the brake pedal
with a 490 N (50 kg, 110 lb) load and measure the
distance between the brake pedal and steering
wheel. With the brake pedal released, measure the
distance between the pedal and steering wheel
again. The difference between the two measure-
ments must be more than specified.

Specified pedal stroke:
Without ABS
90 mm (3.54 in)
With ABS
95 mm (3.74 in)
When depressing brake pedal with a 490
N (50 kg, 110 lb) load.
(1) Models without ABS
If the distance is more than specifications, there
is a possibility that air is in the brake line.
Bleed air from the brake line.
(2) Models with ABS
If the distance is more than specifications, there
is a possibility air is in the inside of the hydrau-
lic unit. Therefore, air must be bled from the
inside of the hydraulic unit to the brake pipes in
accordance with the bleeding sequence control.

8) Add brake fluid to the required level (MAX.
level) of reserve tank.
9) As a final step, test run the vehicle at low speed
and apply brakes relatively hard 2 to 3 times to
ensure that brakes provide normal braking action
on all four wheels without dragging and uneven
braking.

A: REPLACEMENT
CAUTION:
ITo always maintain the brake fluid
characteristics, replace the brake fluid accord-
ing to maintenance schedule or earlier than
that when used in severe condition.
IThe FMVSS No. 116, fresh DOT3 or 4 brake
fluid must be used.
ICover bleeder with waste cloth, when loos-
ening it, to prevent brake fluid from being
splashed over surrounding parts.
IAvoid mixing different brands of brake fluid
to prevent degrading the quality of the fluid.
IBe careful not to allow dirt or dust to get into
the reservoir tank.
NOTE:
IDuring bleeding operation, keep the brake
reserve tank filled with brake fluid to eliminate entry
of air.
IBrake pedal operating must be very slow.
IFor convenience and safety, it is advisable to
have two men working.
IThe amount of brake fluid required is approxi-
mately 500 m(16.9 US fl oz, 17.6 Imp fl oz) for
total brake system.
1) Either jack-up vehicle and place a safety stand
under it, or lift-up vehicle.
2) Remove both front and rear wheels.
3) Draw out the brake fluid from reserve tank with
syringe.
4) Refill reservoir tank with recommended brake
fluid.
