BRAKE FLUID

Check that there is no foreign material in the reservoir tank, and
refill with new brake fluid.

CAUTION:

Never reuse drained brake fluid.

Loosen the bleeder valve, slowly depress the brake pedal to the
full stroke, and then release the pedal. Repeat this operation at
intervals of 2 or 3 seconds until all brake fluid is discharged.
Then close the bleeder valve with the brake pedal depressed.
Repeat the same work on each wheel.

Perform the air bleeding. Refer to

BR-56, "Bleeding Brake Sys-

tem"

Bleeding Brake System

INFOID:0000000010305438

CAUTION:

• Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) con-

nector or the battery negative terminal before performing the work.

• Monitor the fluid level in the reservoir tank during the air bleeding.
• Always use new brake fluid for refilling. Never reuse the drained brake fluid.

Connect a vinyl tube to the bleeder valve of the rear left brake.

Fully depress the brake pedal 4 to 5 times.

Loosen the bleeder valve and bleed air with the brake pedal depressed, and then quickly tighten the
bleeder valve.

Repeat steps 2 and 3 until all of the air is out of the brake line.
In case of EPB rear caliper, operate parkink brake 5 times to bleed the air.

Tighten the bleeder valve to the specified torque. Refer to

BR-80, "BRAKE CALIPER ASSEMBLY :

Exploded View"

(front disc brake),

BR-86, "BRAKE CALIPER ASSEMBLY : Exploded View"

(rear disc

brake).

Perform steps 1 to 5 for the rear left brake

and front left brake in

order.

Check that the fluid level in the reservoir tank is within the specified range after air bleeding. Refer to

OPERATION

Depress the brake pedal several times at 5-second intervals with the
engine stopped. Start the engine with the brake pedal fully
depressed. Check that the clearance between brake pedal and dash
lower panel decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due to
the brake system operation.

AIR TIGHT

• Idle the engine for 1 minute to apply vacuum to the brake booster,

and stop the engine. Then depress the brake pedal several times
at 5-second intervals until the accumulated vacuum is released to
atmospheric pressure. Check that the clearance between brake
pedal and dash lower panel gradually increases (A

→

C) each

time the brake pedal is depressed during this operation.

• Depress the brake pedal with the engine running. Then stop the

engine while holding down the brake pedal. Check that the brake
pedal stroke does not change after holding down the brake pedal
for 30 seconds or more.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due
to the brake system operation.

FRONT DISC BRAKE

BRAKE PAD

INFOID:0000000010305441

PAD WEAR

Check pad thickness from an inspection hole on cylinder body.
Check using a scale if necessary.

DISC ROTOR

DISC ROTOR : Inspection

INFOID:0000000010305442

APPEARANCE

Check surface of disc rotor for uneven wear, cracks, and serious damage. Replace if there are.

RUNOUT

Fix the disc rotor to the wheel hub and bearing assembly with
wheel nuts (2 points at least).

Inspect the runout with a dial gauge. [Measured at 10 mm (0.39
in) inside the disc edge.]

NOTE:
Check the wheel bearing axial end play before the inspection.
Refer to

FAX-8, "Inspection"

(2WD),

FAX-47, "Inspection"

(4WD).

Find the installation position with a minimum runout by shifting the disc rotor-to-wheel hub and bearing
assembly installation position by one hole at a time if the runout exceeds the limit value.

Replace or lathe the disc rotor if the runout exceeds the limit even after the above operation.

THICKNESS

Check the thickness of the disc rotor using a micrometer. Replace
the disc rotor if the thickness is below the wear limit.
