BRAKE FLUID
BLEEDING
HINT:

If any work is done on the brake system or if air in the
brake lines is suspected, bleed the air from the system.

When bleeding, keep the amount of the fluid within the
line of reservoir between Min. and Max.
NOTICE:

Do not let brake fluid remain on painted surfaces.
Wash it off immediately.

With the reservoir cap removed, when depressing the
brake pedal, the fluid will spray.
1. FILL RESERVOIR WITH BRAKE FLUID
Fluid: SAE J1703 or FMVSS NO. 116 DOT3
2. In case of using TOYOTA hand-held tester:
BLEED HYDRAULIC BRAKE BOOSTER
HINT:
If the hydraulic brake booster has been disassembled, discon-
nect the brake line from the hydraulic brake booster or if the res-
ervoir becomes empty, bleed the hydraulic brake booster.
(a) Turn the ignition switch OFF, depress the brake pedal
more than 40 times.
HINT:
When a pressure in power supply system is released, reaction
force becomes light and stroke becomes longer.
(b) Turn the ignition switch ON, check that the pump stops af-
ter approx. 30 to 40 sec.
NOTICE:
When the pump does not stop, repeat step (a) and (b) again.
(c) With the ignition switch remained ON, depress the brake
pedal more than 20 times.
(d) Observe the procedure in step 4 and bleed the right and
left front brake caliper.
(e) Holding the brake pedal depressed, bleed the right and
left rear brake caliper.
HINT:
It is not necessary to depress the pedal continuously, as brake
fluid flows out by first depressing.
(f) Connect TOYOTA hand-held tester.
(1) Turn the ignition switch OFF, connect the TOYOTA
hand-held tester to DLC3.
(2) Turn the ignition switch ON and select ºAIR BLEED-
INGº on the TOYOTA hand-held tester.
HINT:
Please refer to the TOYOTA hand-held tester operator's manu-
al for further details.

(c) At the point when fluid stops coming out, tighten the
bleeder plug, then release the brake pedal.
(d) Repeat (b) and (c) until all the air in the fluid has been bled
out.
(e) Repeat the above procedure to bleed the brake line for
each wheel.
