OPERATION
1. Refer to the vehicle service manual for
instructions on using an appropriate
lifting device to hoist the vehicle off the
ground. Lift the vehicle just far enough
to remove the wheel and tire.
2. After removing the wheel, completely
thread two lug nuts back onto two
opposing wheel studs. Back off the lug
nuts three or four turns to allow the
drum to be pulled away from, but not fall
off, the wheel hub. See Figure 1.
3. Estimate the diameter of the brake
drum. Using the marks on the puller
crossbar as a guide, set the jaws an
equal distance apart from the center on
each side of the brake drum.
4. With the forcing screw at the center of
the wheel hub, position the puller jaws
in the groove between the brake drum
and the backing plate. Adjust the jaws
on the crossbar as needed to t.
5. Verify the jaws have good contact with
the drum, and hand-tighten the forcing
screw to the wheel hub.
6. Place the strap (provided) over the
puller and brake drum. Position it
around the outer edge of the drum and
within the tabs of the jaws. Cinch the
strap tightly in place. See Figure 2.
7. Using a ratchet or impact wrench, turn
the forcing screw inward just enough to
remove the brake drum.
8. Remove the strap and the puller from
the brake drum. Remove the lug nuts
and remove the brake drum.
