FRONT DISC BRAKE
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any of them is detected, replace
applicable part.
Runout Inspection
1. Using wheel nuts, fix disc rotor to wheels hub. (2 or more positions)
2. Using a dial indicator, check runout.
CAUTION:
Before measuring, make sure that axle end play within the
specification before measuring runout. FAX-5 , "
WHEEL
BEARING INSPECTION" .
3. If runout is outside the limit, find the minimum runout point by
shifting the mounting positions of disc rotor and wheel hub by
one hole.
4. If runout is still out of specification, turn rotor with on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and
705” or equivalent).
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specification, replace disc rotor.
BRAKE BURNISHING PROCEDURE
Burnish contact surfaces between disc rotors and pads according to following procedure after refinishing or
replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage.
CAUTION:
Be careful of vehicle speed because the brake does not operate easily until pad 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 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.Measurement point: At a point 10.0 mm (0.394 in)
from outer edge of disc.
Runout limit : 0.040 mm (0.0016 in) or less
SBR019B
Standard thickness : 24.0 mm (0.945 in)
Wear limit : 22.0 mm (0.866 in)
Maximum uneven wear
(measured at 8 positions): 0.010 mm (0.0004 in)
or less

3. If runout is outside the limit, find minimum runout point by shift-
ing mounting positions of disc rotor and wheel hub by one hole.
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If thickness is out-
side the specification, replace disc rotor.
BRAKE BURNISHING PROCEDURE
Burnish brake pad or lining contact surfaces of rotor according to following procedure after refinishing or
replacing drums or rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage.
CAUTION:
Be careful of vehicle speed because brake does not operate easily until pad 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 vehicle stops.
3. Drive without depressing brake for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.Measurement point: At a point 10 mm (0.394 in)
