The operation stops automatically in 4 seconds.

At this time, be sure to release the brake pedal.
(3) Check that the operation has stopped, by referring
to the hand-held tester display.
(4) Repeat (2) and (3) until all the air in the fluid is com-
pletely bled out.
(5) Tighten the bleeder plug certainly.
Torque: 8.3 NVm (85 kgfVcm, 73 in.Vlbf)
(6) For the rest of the wheels, bleed the air in the same
way as stated in the above procedure.
(f) Bleed the air out of the pressure reduction line in ºStep3:
Decreaseº on the hand-held tester display.
NOTICE:

Perform air bleeding by following the steps displayed
on the hand-held tester.

Make sure that the brake fluid in the master cylinder
reservoir tank does not become empty.
(1) Connect a vinyl tube to either one of the bleeder
plugs.
(2) Loosen the bleeder plug.
(3) Using the hand-held tester, operate the brake ac-
tuator assy using hand-held tester, completely de-
press the brake pedal and keep it.
NOTICE:

The operation stops automatically in 4 seconds.
When performing this procedure continuously, an in-
terval of at least 20 seconds is required.

When the operation is completed, the brake pedal
slightly goes down. This is a normal phenomenon
caused when the solenoid opens.

During this procedure, the pedal seems heavy, but
completely depress it so that the brake fluid comes
out from the bleeder plug.

Be sure to keep depressing the brake pedal. Never
depress and release the pedal repeatedly.
