AIR BLEEDlNG (WITH ABS)
Front Brakes
1. Fill the fluid reservoir to the MAX line with the specified brake
fluid.
Caution
l The brake fluid reservoir must remain 3/4 full dur-
ing air bleeding.
l Be careful not to spill brake fluid onto a painted
surface.
l Use only the specified brake fluid. Do not mix it with
any other type.
2. Jack up the vehicle and support it on safety stands.
3. Remove the bleeder cap and attach a vinyl hose to the
bleeder screw.
4. PIace the other end of the vinyl hose into a clear fluid-filled
container.
5. Have an assistant depress the brake pedal a few times, and
then hold it depressed.
6. Using the SST, loosen the bleeder screw and drain out the
fluid and air. Retighten the bleeder screw.
Caution
l The two persons should stay in voice contact with
each other.
l Be sure the pedal remains depressed until the air
bleed screw is tightened.
7. Repeat Steps 5 and 6 until no air bubbles are seen.
8. Check for ‘correct brake operation.

Rear Brakes
1. Fill the fluid reservoir to the MAX mark with the specified
brake fluid.
2. With the ignition switch ON, fully depress the brake pedal
several times.
3. When the hydraulic-unit pump stops add the specified brake

If the hydraulic-unit pump coniinJes tti run for more than
one minute, do the following:
(1) Jack up the vehicle and support it on safety stands.
(2) Remove the bleeder cap and attach a vinyl hose to the
bleeder screw.
(3) Insert the other end of the vinyl hose into a clear con-
tainer.
(4) Loosen the bleeder screw by using the SST.
(5) With the ignition switch ON, fully depress the brake pedal
several times.
(6) Tighten the bleeder screw and continue with Step 2 of
the main procedure.
Cautfon
l Do not run the hydraulic-unit pump for more than
two minutes.
l The brake fluid reservoir must be kept 3/4 fult dur-
ing air bleeding.
