A: INSPECTION
1) Check that the brake fluid level remains between
"MIN" and "MAX'. If out of the specified range, refill
or drain fluid. If fluid level becomes close to "MIN",
refill fluid.
2) Check the fluid for discoloration. If fluid color has
excessively changed, drain the fluid and refill with
new fluid.
B: REPLACEMENT
CAUTION:
To always maintain the brake fluid character-
istics, replace the brake fluid according to
maintenance schedule or earlier than that when
used in severe condition.
The FMVSS No. 116, fresh DOT3 or 4 brake
fluid must be used.
Cover the bleeder with waste cloth, when
loosening it, to prevent brake fluid from being
splashed over surrounding parts.
Avoid mixing different brands of brake fluid
to prevent degrading the quality of the fluid.
Be careful not to allow dirt or dust to get into
the reservoir tank.
NOTE:
During bleeding operation, keep the brake reser-
voir tank filled with brake fluid to eliminate entry of
air.
Brake pedal operating must be very slow.
For convenience and safety, two people should
do the work.
The amount of brake fluid required is approxi-
mately 500 m 0 (1 6.9 US fl oz, 17.6 Imp fl oz) for to-
tal brake system.
1) Either jack-up the vehicle and place a safety
stand under it, or lift up the vehicle.
2) Remove both front and rear wheels.
3)
Draw out the brake fluid from master cylinder
with syringe.
4) Refill the reservoir tank with recommended
brake fluid.

FMVSS No. 116, fresh DOT3 or 4 brake fluid
