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.
