DISC PLATE THICKNESS INSPECTION
1. Measure the thickness of the disc plate.

Caution: When it is necessary to machine the disc plate, if the disc plate is removed from the vehicle then machined, excessive runout may result. Machine the disc plate with it installed on the vehicle.

Thickness
Standard: 28 mm (1.10 inch)
Minimum: 26 mm (1.02 inch)
Minimum thickness after machining by using a brake lathe on-vehicle: 26.8 mm (1.05 inch)

2. If the thickness is not within the specification, replace the disc plate.

DISC PLATE RUNOUT INSPECTION
1. Verify that there is no wheel bearing looseness.





2. Measure the runout at the outer edge of the contact surface of the disc pad.

Runout: 0.05 mm (0.002 inch) max.

3. If the runout is not within the specification, repair or replace the disc plate.

DISC PLATE DIAMETER INSPECTION
1. Remove the disc plate.
2. Inspect the inside of disc plate for scratches and uneven or abnormal wear.





3. Measure the disc plate inner diameter.

Inner diameter: 191.0 mm (7.52 inch) max.

4. If the diameter is not within the specification, replace the disc plate.
