BRAKE FLUID LEVEL

• Check that the fluid level in the sub tank is within the specified

range (MAX – MIN lines).

• Visually check for any brake fluid leakage around the sub tank,

reservoir tank and hose.

• Check the brake system for any leakage if the fluid level is

extremely low (lower than MIN).

• Check the brake system for fluid leakage if the warning lamp

remains illuminated even after the parking brake is released.

BRAKE LINE

1.

Check brake line (tubes and hoses) for cracks, deterioration or other damage. Replace any damaged
parts.

2.

Check for fluid leakage by fully depressing brake pedal while
engine is running.

CAUTION:

If leakage occurs around joints, retighten or, if necessary,
replace damaged parts.

Draining

INFOID:0000000008456201

CAUTION:

• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it

off immediately and wash with water if it gets on a painted surface.

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

nector or the battery negative terminal before draining.

1.

Connect a vinyl tube to the bleed valve.

2.

Depress the brake pedal and loosen the bleeder valve to gradu-
ally discharge brake fluid.

Refilling

INFOID:0000000008456202

CAUTION:

Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) connec-
tor or the battery negative terminal before refilling.

1.

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

CAUTION:

Never reuse drained brake fluid.

2.

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.

3.

Perform the air bleeding. Refer to 

BR-12, "Bleeding Brake System"

.

Bleeding Brake System

INFOID:0000000008713783

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 sub tank during the air bleeding.
• Always use new brake fluid for refilling. Never reuse the drained brake fluid.

1.

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

2.

Fully depress the brake pedal 4 to 5 times.

3.

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

4.

Repeat steps 2 and 3 until all of the air is out of the brake line.

5.

Tighten the bleeder valve to the specified torque.
• Front disc brake

BRAKE BOOSTER

Inspection

INFOID:0000000008456205

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 

→

 B 

→

 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.

INSPECTION

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

ADJUSTMENT

CAUTION:

• Burnish contact surfaces between pads according to the following procedure after refinishing or

replacing pads, or if a soft pedal occurs at very low mileage.

• Be careful of vehicle speed because the brake does not operate firmly/securely until pads and disc

rotor are securely fitted.

• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1.

Drive vehicle on straight, flat road.

2.

Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.

3.

Drive without depressing brake for a few minutes to cool the brake.

4.

INSPECTION

Appearance

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

Runout

1.

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

2.

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

FAX-8, "Inspection"

 (2WD), 

FAX-34, "Inspection"

(AWD).   

3.

Inspect the runout with a dial gauge to measured at 10 mm (0.39
in) inside the disc edge.

4.

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.

5.

Refinish the disc rotor if the runout is outside the limit even after performing the above operation. [When
refinishing, use the Pro-Cut PEM On-Car brake Lathe (Tool No. 38-PFM90.5) or equivalent.]
