Mazdaspeed6 L4-2.3L Turbo (2006)
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 10.39 inch), inner diameter more than
12 mm 10.47 inch)) between the hub bolt and the hub nut.
Note:
^
The component parts of the SST (49 B01 7 001 or 49 G01 9 003) 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 inch) from the disc plate
edge.
3. Rotate the disc plate one time and measure the runout.
Front disc plate runout limit 0.05 mm (0.002 inch)
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 (0.0005 inch)
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 front disc plate thickness 23 mm (0.91 inch)
Minimum front disc plate thickness after machining using a brake lathe on-vehicle 23.8 mm (0.94 inch)
