FRONT DISC BRAKE


DISC ROTOR : Inspection


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

RUNOUT





1. Attach the disc rotor to wheel hub using wheel nuts at two or more positions.
2. Inspect runout using a dial gauge. Set the dial gauge to measure at 10 mm (0.39 in) inside the disc edge.

Maximum runout : Refer to Front Disc Brake

NOTE:
Before measuring, make sure that wheel bearing axial end play is within the specification. Refer to Testing and Inspection.
3. When runout exceeds limit value, displace mounting positions of disc rotor by one hole. And then find a position of the minimum value for runout.
4. If runout is outside the specified value after performing the above operation, turn the disc rotor using Tool.

Tool number : 38-PFM90.5


THICKNESS





Check thickness of the disc rotor using a micrometer. Replace disc rotor if thickness is under the wear limit.
