If runout is still outside the limit after performing the above operation, replace or lathe the disc rotor.
[When lathing, use the Pro-Cut PFM On-Car Brake Lathe (Tool No, 38-PFM90.5) 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
INFOID:0000000001327638
Burnish the 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:

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 brake.
4.
Repeat steps 1 to 3 until pad and disc rotor are securely fitted.
