INFOID:0000000005986574
INSPECTION
Check brake pad wear thickness from an inspection hole on cylinder
body. Check using a scale if necessary.
ADJUSTMENT
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.
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.

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.
