INFOID:0000000009364825

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.

FRONT DISC BRAKE

BRAKE PAD

INFOID:0000000009364826

INSPECTION

Check brake pad wear thickness from an inspection hole on cylinder

body. Check using a scale if necessary. 

BRAKE PAD : Brake Burnishing

INFOID:0000000009671177

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

INFOID:0000000009364827

INSPECTION

Appearance

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

to 

BR-44, "Front Disc Brake"

.

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.

CAUTION:

If the thickness is less than wear thickness + 0.3 mm (0.012 in), replace the disc brake rotor. Refer

to 

BR-36, "BRAKE CALIPER ASSEMBLY : Removal and Installation"

.

Thickness

Check the thickness of the disc brake rotor using a micrometer.

Replace the disc brake rotor if the thickness is below the wear limit.
