REMOVAL

BRAKE SHOE REMOVAL

The removal, disassembly, cleaning and reassembly

instructions presented are primarily for reference.

Disassembly, particularly of the wheel cylinders and

expanders, should not be attempted without the proper

maintenance kits on hand. Damage to some parts may

occur as a result of disassembly. Maintenance kits are

available from your local authorized Bendix parts outlet.

1. Park the vehicle on a level surface and prevent vehicle

movement by a means other than with the parking brake.

Shut off engine.

2. Manually cage all hydraulic spring actuators, raise the

axle and remove the wheels and tires using the procedure

recommended by the vehicle manufacturer 's

maintenance manual.

3. Un-adjust the vehicle brake shoes as follows:

A. Remove the rubber grommets from the manual

override access holes marked "ADJ" in the backing

plate (dirtshield), and insert a blunt screwdriver, or

adjusting tool, until it engages the manual override

wheel. Refer to Figure 10.

B. Using the backing plate (dirtshield) as a fulcrum,

Figure 11, turn the override wheel in a CLOCKWISE

direction, as viewed from the override wheel end until

the lining clears the lip in the drum. Watch the lining

through the lining inspection hole, Figure 26.

C. Repeat this procedure with the other brake shoe and

remove the drum. IMPORTANT: Do not apply

service or park brake after drums have been

removed.
