BRAKE FLUID

1. Check that there is no foreign material in the reservoir tank, and

refill with new brake fluid. Refer to 

MA-12, "Fluids and Lubri-

cants"

.

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 new 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 procedure. Refer to 

BR-12, "Bleeding

Brake System"

.

Bleeding Brake System

INFOID:0000000009364993

CAUTION:

• Turn the ignition switch OFF and disconnect ABS actuator and electric unit (control unit) or battery

negative terminal before performing the work.

• Monitor the fluid level in the reservoir tank while performing the air bleeding.

• Do not 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.

• Always use new brake fluid for refilling. Do not reuse drained brake fluid.

• Do not allow foreign matter (e.g. dust) and oils other than brake fluid to enter the reservoir tank.
1. Connect a vinyl tube to the bleeder valve.
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: Refer to 

BR-35, "BRAKE CALIPER ASSEMBLY : Exploded View"

.

• Rear drum brake: Refer to 

BR-40, "Exploded View"

.

6. Perform steps 1 to 5 in the following order: Front (RH) brake 

→ front (LH) brake → rear (RH) brake → rear

(LH) brake.

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

BR-

11, "Inspection"

.

8. Add brake fluid as necessary to keep the brake fluid level within the specified range. Refer to 

MA-12, "Flu-

ids and Lubricants"

.

9. Inspect the brake pedal height and play. Adjust it if the measurement value is not the standard. Refer to

BR-8, "Inspection and Adjustment"

.

Inspection

INFOID:0000000009364995

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

1. Run the engine at idle 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 each time the brake pedal is depressed when performing this operation.

2. 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 sec-

onds or more.

BRAKE PAD

INFOID:0000000009364996

INSPECTION

Check brake pad wear thickness from an inspection hole on cylinder

body. Check using a scale if necessary. 

BRAKE PAD : Brake Burnishing

INFOID:0000000009671178

BRAKE BURNISHING

Burnish contact surfaces between disc brake rotor and brake pads according to the following procedure after

refinishing disc brake rotors, replacing disc brake rotors, replacing brake pads, or if a soft pedal occurs at very

low mileage:

CAUTION:

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

disc brake rotor are securely seated.

• 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 pedal for a few minutes to cool the brakes.
4. Repeat steps 1 to 3 until pad and disc brake rotor are securely seated.

DISC ROTOR
DISC ROTOR : Inspection

INFOID:0000000009364997

INSPECTION

Appearance

Check surface of disc brake rotor for uneven wear, cracks, and serious damage. Replace it if necessary. Refer

to 

BR-15, "DISC ROTOR : Inspection"

.

Runout

1. Secure the disc brake rotor to the wheel hub with wheel nuts (2

points at least).

2. Check the wheel bearing axial end play before the inspection.

Refer to 

FAX-7, "Inspection"

.

3. Inspect the runout with a dial indicator to measure at 10 mm

(0.39 in) inside the disc edge.

4. Find the installation position that has a minimum runout by shift-

ing the disc brake rotor-to-wheel hub installation position by one

hole at a time if the runout exceeds the limit value.

5. Refinish or replace the disc brake rotor if the runout is outside the limit even after performing the above

operation.
