BRAKE PAD : Inspection and Adjustment

INFOID:0000000009722311

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.

Repeat steps 1 to 3 until pad and disc rotor are securely fitted.

DISC ROTOR

DISC ROTOR : Inspection and Adjustment

INFOID:0000000009722312

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 

RAX-6, "Inspection"

 (2WD), 

RAX-13, "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.]

• Check in advance that the thickness of the disc rotor is wear thickness + 0.3 mm (0.012 in) or

more.

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

Thickness

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

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
