5) Perform these steps for the brakes connecting
to the secondary chamber of master cylinder, first,
and then for the ones connecting to primary cham-
ber. With all procedures completed, fully depress
the brake pedal and keep it in that position for
approximately 20 seconds to make sure that there
is no leak evident in the entire system.
6) 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.
If the distance is more than the specifications,
there is a possibility that air is in the brake line.
Bleed air from the brake line.
(1) Steering wheel
(2) Toe board
Specified pedal stroke:
95 mm (3.74 in)
When depressing brake pedal with a 490
N (50 kg, 110 lb) load.
7) After air bleeding is completed, operate
sequence control to check pedal stroke. If it is
longer than specified, repeat air bleeding opera-
tion. <Ref. to 4-4 [W15D0].>
8) Add brake fluid to the required level (MAX.
level) of reservoir 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
11. Brake Fluid
¼ To always maintain the brake fluid
characteristics, replace the brake fluid accord-
ing to maintenance schedule or earlier than
that when used in severe condition.
¼ The FMVSS No. 116, fresh DOT3 or 4 brake
fluid must be used.
¼ Cover bleeder with waste cloth, when loos-
ening it, to prevent brake fluid from being
splashed over surrounding parts.
¼ Avoid mixing different brands of brake fluid
to prevent degrading the quality of the fluid.
¼ Be careful not to allow dirt or dust to get into
the reservoir tank.
¼ During bleeding operation, keep the brake res-
ervoir tank filled with brake fluid to eliminate entry
¼ Brake pedal operating must be very slow.
¼ For convenience and safety, it is advisable to
have two men working.
¼ The 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 left up vehicle.
2) Remove both front and rear wheels.
3) Draw out the brake fluid from master cylinder
4) Refill reservoir tank with recommended brake
