Pic. 6.35. Marking the hub bolt and brake disc
Mark the wheel hub bolt and brake disc prior to removal for refitting (pic. 6.35).
Loosen the mounting bolt and remove the brake hose.
Remove the guide pin cover and the pin itself.
Pic. 6.36. Measuring the thickness of the brake disc
Using a micrometer, measure the thickness of the brake disc (pic. 6.36).
- Standard thickness: 26 mm.
- Minimum thickness: 24 mm.
Replace the disc if the disc thickness is less than the minimum allowable.
Attach the brake disc to the wheel hub with wheel nuts (two or more places).
Pic. 6.37. Checking disc runout with an indicator
Check the beat with an indicator (pic. 6.37).
- Measuring point: 10 mm from the outer edge of the disc.
- Maximum runout: 0.05mm or less.
Attention! Make sure the end play is 0 mm before taking a measurement.
If the runout is significant, find the point of minimum runout by successively shifting the installation position of the brake disc on the hub by one hole.
Remove rust or dirt from the contact surface of the brake disc and wheel hub.
Establish a brake disk and align marks made before removal.
