Rear

Inspection and repair procedure

Inspection And Repair Procedure:

Lateral runout inspection
1. To secure the disc plate and the hub, tighten the hub nuts upside down or insert a washer (thickness 10 mm (0.39 in) with an inner diameter more than 12 mm (0.47 in)) between the hub bolt and the hub nut.

Note
^ The component parts of the SST (49 B017 001 or 49 G019 003) can be used as a suitable washer.

2. After tightening all the hub nuts to the same torque, put the dial gauge on the friction surface of disc plate 10 mm (0.39 in) from the disc plate edge.
3. Rotate the disc plate one time and measure the runout.
Rear disc plate runout limit 0.05 mm (0.002 in)

Thickness variation inspection
1. Clean the disc plate-to-pad friction surface using a brake cleaner.
2. Measure the points indicated in the illustration using a caliper (micrometer).





3. Subtract the minimum value from the maximum.
^ If the result is not within specification, machine the disc plate using a lathe.

Thickness variation limit 0.015 mm (0.0005 in)

Warning
^ Do not exceed minimum disc plate thickness.
