1. Place vehicle on car lift and put transmission in neutral.
2. Raise lift and place vehicle at correct working height, Fig. 24.
3. Check wheel bearing play on both sides of vehicle Fig. 25.
4. If necessary, adjust wheel bearing tolerances as described by the workshop
manual.
5. Immediately after removing the wheel, secure the brake rotor to the hub to pre-
vent dirt particles from accumulating between rotor and hub.
Use a brake pedal depressor to lock the brake rotor.
NOTE: Brake rotors are not all mounted to a hub with a screw or nut.
6. Remove the wheel and secure the brake rotor with the wheel nuts (or bolts) and
conical rings, Fig. 26-27.
7. Mount the drive adapter to one of the wheel nuts (or bolts), Fig. 27.
8. The V-shape of the drive adapter must seat firmly along the edge of the hub.
9. Tighten the wheel nuts or bolts evenly to 50 Nm (37 Ft-Lbs).
10. Remove the wheel on the other side of the vehicle and secure that brake rotor
with two wheel nuts (or bolts) and conical rings.
11. Remove he brake pedal depressor.
12. Check the thickness of the brake rotor, to ensure that the rotor will not be below
minimum thickness after machining.
13. Refer to the service manual for the minimum brake rotor thickness.
14. If the brake rotor is below minimum thickness, it must be replaced. Machining of
a rotor below minimum thickness is not permitted.
15. If the brake rotor is thicker than the discard size, determine the maximum
amount that could be machined off, for each side of the brake rotor.
16. Remove the complete brake caliper and hang it on the S-hook, Fig. 28.
17. Check that the brake line and caliper do not come in contact with the drive shaft
(or any other rotating part).
18. Remove rust and dirt from the mounting surface of the caliper mounting lugs.
The lugs must be clean, as they are the reference point for machining the brake
surface.
19. Fit the rubber silencer band around the outer edge of the brake rotor to help re-
duce noise and vibration, Fig. 29.
20. Connect the cable to the Drive Unit and the mains power supply.
21. Connect the cable between Drive Unit and Lathe.
22. Set the motor switch to position 0, then unlock the emergency switch.
23. Move the slides and bit holders of the Lathe in the most rear position. (By turning
the hand wheel anticlockwise).
24. In this position the tool bits cannot be damaged by touching the brake rotor.
