BRAKE PAD : Inspection and Adjustment

INFOID:0000000009651811

INSPECTION

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

ADJUSTMENT

Burnish contact surfaces between disc rotor and brake pads according to the following procedure after refin-
ishing or replacing brake pads, or if a soft pedal occurs at very low mileage.

CAUTION:

• 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 : Inspection and Adjustment

INFOID:0000000009651812

INSPECTION

Appearance

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

RAX-6, "Removal and Installation"

.

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-4, "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 rotor-to-wheel hub and bearing assembly installation
position by one hole at a time if the runout exceeds the limit value.

• 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.]

CAUTION:

• 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. Refer to

RAX-6, "Removal and Installation"

.

Thickness

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

RAX-6,

"Removal and Installation"

.

ADJUSTMENT

Burnish contact surfaces between disc rotors and brake pads according to the following procedure after refin-
ishing or replacing disc rotor, or if a soft pedal occurs at very low mileage.

CAUTION:

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

rotor are securely fitted.
