FRONT DISC BRAKE

DISC ROTOR : Inspection and Adjustment


Visual inspection

Check surface of the disc rotor for uneven wear, cracks, and serious damage. Replace if necessary. Refer to
"Removal and Installation" Removal And Installation.

RUNOUT INSPECTION

1.Use the wheel nuts and fasten the disc rotor to the wheel hub assembly (minimum 2 positions).
2.Check axial end play of wheel hub assembly. "Inspection" Inspection.





3.Check runout using a dial indicator [at 10 mm (0.39 in) from outer edge of disc rotor].
Maximum runout : Refer to {LINK_TO_MANY:0000000007635894}{LINK_TO_MANY:0000000007635895}{LINK_TO_MANY:0000000007635896}{LINK_TO_MANY:0000000007635897}{LINK_TO_MANY:0000000007635898}, "Front Disc


(vehicle stopped)Brake".
4.If runout is outside the specified value, find the minimum runout point by shifting mounting positions of the disc rotor and wheel hub by one hole.
5.Perform grinding of disc rotor if runout is outside the specified value after performing the above operation. [When refinishing, use the Pro-Cut PEM On-Car brake Lathe (Tool No. 38PFM90.5) or equivalent.]

CAUTION:
- Perform grinding of disc rotor if disc rotor thickness is 0.3 mm (0.012 in) or more above the wear limit thickness.
- Replace disc rotor if disc rotor thickness is less than 0.3 (0.012 in) above the wear limit thickness. Refer to "Removal and Installation" Removal And Installation.


Wear limit : Refer to "Front Disc Brake" Front Disc Brake.

THICKNESS INSPECTION






Check thickness of the disc rotor using a micrometer. Replace disc rotor if thickness is under the wear limit. "Removal and Installation" Removal And Installation.

ADJUSTMENT

If the brake pad is ground or replaced, or if there is an abnormal feel to the braking force, follow the procedure below and perform break-in work.

CAUTION:
- Because the brake effectiveness is reduced, pay sufficient attention to the vehicle speed.
- Perform checks on a safe road and be careful of the traffic conditions.
1.Drive on straight and flat roads.
2.Stop the vehicle by depressing the brake pedal to generate braking force that stops the vehicle in 3 to 5
seconds.
3.Cool the brakes.
4.Repeat steps 1 to 3 until the abnormal feel in braking force disappears.
