nine models of H brakes. Several of the designs
are shown in Figure 2.17.
WARNING
Some brake linings contain asbestos fibers, a
cancer and lung disease hazard. Some brake
linings contain non-asbestos fibers, whose long-
term effects to health are unknown. You must
use caution when you handle both asbestos and
non-asbestos materials.

WARNING
Block the wheels to prevent the vehicle from
moving. Support the vehicle with safety stands.
Do not work under a vehicle supported only by
jacks. Jacks can slip and fall over. Serious personal
injury can result.
1. Make sure the vehicle is on a level surface.
2. Place blocks under the wheels not being
serviced to keep the vehicle from moving.
3. Raise the vehicle so that the wheels to be
serviced are off the ground. Support the
vehicle with safety stands.
4. Remove the wheels and brake drums from the
axle. If necessary, manually retract the brake
shoes by rotating the adjustment cams from
the back of the brake so that the brake drums
will clear the linings.
