not machine a new brake disc.
7. For vehicles with a two-piece hub and brake disc assembly:
Match-mark before disassembly.
Remove the brake disc.
Using a die grinder with a mild abrasive (Scotch Brite® type), remove any rust or
corrosion from the hub and brake disc mounting surfaces.
Align the match-marks and reinstall the brake disc on the hub.
8. CAUTION: Do not use a bench lathe to machine brake discs.
NOTE: The depth of cut must be between 0.10 and 0.20 mm (0.004 and 0.008 inch). Lighter
cuts will cause heat and wear. Heavier cuts will cause poor brake disc surface finish.
Using on-vehicle brake lathe, machine the brake discs. Follow the manufacturer's instructions.
After machining, make sure the brake disc still meets the thickness specification.
9. Using a dial indicator, verify that the brake disc lateral runout is now within vehicle specification.
10. Remove any metal chips.
11. Remove the hub adapter.
12. Remove any remaining metal chips from the machining operation.
13. CAUTION: Do not carry out this step on rear drum-in-hat brake discs.
For vehicles with a two-piece hub and a non drum-in-hat brake disc assembly:
Remove the brake disc from the hub.
Remove any remaining metal chips from hub and brake disc mounting surfaces and from
the ABS sensor.
Apply High Temperature Nickel Anti-Seize Lubricant F6AZ-9L494-AA to the mounting
surfaces.
Using the match-marks, mount the brake disc on the hub.
