Rear Brake (Disc) InspectionInspection and repair procedure
Lateral runout inspection
1. To secure the disc plate and the hub, insert the washer (thickness 10 mm (0.39 in), inner diameter more than 12 mm (0.47 in)) between each hub bolt and the hub nut, then tighten all the hub nuts.
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, and if the result is not within specification, machine the disc plate using a lathe.
Thickness variation limit 0.015 mm (0.00059 in)
Warning
^ Do not exceed minimum disc plate thickness.
Disc Plate Thickness Inspection
Caution
^ Excessive runout may result if the disc plate is removed from the vehicle then machined. Machine the disc plate while installed on the vehicle.
1. Measure the thickness of the disc plate.
^ If the thickness is not within the specification, replace the disc plate.
Minimum rear disc plate thickness 8 mm (0.31 in)
Minimum rear disc plate thickness after machining using a brake lathe on-vehicle 8.8 mm (0.35 in)
