The lathe should also be equipped with a grinder
attachment or dual sanding discs for light refinish-
ing, or final cleanup.
If the rotor surfaces only need minor cleanup of
rust, scale, or scoring, use abrasive discs to clean up
the rotor surfaces. However, when a rotor is scored or
worn, machining with cutting tools will be required.
CAUTION: Do not refinish a rotor if machining
would cause the rotor t o fall below minimum allow­
able thickness.
The recommended final finish on a rotor braking
surface is shown in Figure 34. The final finish should
be a non-directional, cross hatch pattern. Sanding
discs are required to produce this type of finish.
DISC BRAKE ROTOR REMOVAL (WITH TAPERED
BEARINGS)
(1) Raise vehicle.
(2) Remove wheel and tire assembly.
(3) Bottom caliper piston in bore. Use screwdriver
or large C-clamp to press piston back to bottom of
caliper bore (Fig. 7).
(4) Remove caliper mounting bolts (Figs. 8 and 9).
(5) Remove caliper from rotor. Position caliper on
steering knuckle and secure it with wire (Figs. 13
and 14).
CAUTION: Do not allow the brake hose to support
the caliper. Suspending the caliper by the brake
hose can damage the hose and fitting joints. Use
wire to support and secure the caliper to a suspen­
sion component as shown (Figs. 13 and 14).
(6) On models with removable adapter hub, re­
move hub from rotor.

(7) On models with one-piece rotor and hub assem­
bly, remove grease cap that covers cotter pin and hub
nut.
(8) Remove grease cap from hub. On models with
long adapter, use long pry tool with angled end to re­
move grease cap. Pry against flats at each side of cap
to loosen and remove it.
(9) Remove cotter pin from spindle and wheel bear­
ing adjusting nut (Fig. 35).
(10) Remove locknut from wheel bearing adjusting
nut. Then remove tabbed thrust washer and outer
wheel bearing (Fig. 35).
