BLEEDING
Caution
Specified brake fluid: DOT3 or DOT4
1. Always use the specified brake fluid. Avoid using
a mixture of the specified brake fluid and other fluid.
2. Maintain the fluid reservoir level between the MIN
and MAX marks during the air bleeding.
3. Do not depress the brake pedal hard during the air
bleeding (normal air bleeding) to prevent the pump
motor from operating frequently.
4. After the air bleeding, check that the brake dragging
does not become stronger.
5. If the pedal is depressed with the reservoir cap
removed, the brake fluid may overflow. Do not depress
the brake pedal while the fluid is being added.
NORMAL AIR BLEEDING
After the front brake or the rear brake is removed and installed,
some fluid may remain in the hydraulic brake booster (HBB)
reservoir. In this case, bleed air from the brake caliper.
HBB SYSTEM AIR BLEEDING
If all the brake fluid inside the reservoir is drained due to
the removal and installation of the HBB, bleed air as follows:
Air bleeding from front brake system
1. Turn the ignition switch to the LOCK (OFF) position. Bleed
air from the front brake calipers (right and left) by pumping
the brake pedal.
Pump motor operation
2. Turn the ignition switch ON, and operate the pump motor.
If the pump motor is running free, supply the brake fluid
into the pump motor by depressing the brake pedal three
or four times.
Air bleeding from accumulator system
3. After the pump motor stopped, depress the brake pedal
three or four times with the ignition switch ON. Then
observe the brake fluid in the reservoir. If the brake fluid
looks whitish, wait for a few minutes until it becomes
clear.
4. Repeat step 3 until the brake fluid becomes clear.
