Mechanical Brakes
Assemble DLM Brake
CAUTION
Do not permit grease to contact the brake drum
or linings. Grease on the linings can cause poor
brake performance. Contaminated linings MUST
be replaced.
1. Before assembly, apply a thin layer of Meritor
specification 0-616 brake lubricant such as
Texaco Thermatex EP-2 grease or equivalent
(listed on page 31) to the following parts:
a. The sides of the brake lever and shoes that
slide against each other.
b. The ends of the shoe webs.
c. The surfaces of the wear pads and actuating
pawls.
2. If it was removed, install the brake backing
plate in the same position as marked in Step 10
of the Disassembly Section. Tighten the
capscrews to the specifications set by the
vehicle builder.
3. Put the roller(s) in position on the actuator
pawl pin at the lever opening on the backing
plate.
4. Install the brake actuator lever with the large
hole in the tab over the pawl pin that is
opposite the actuator pawl. Set the lever arm in
the backing plate opening with the outer edge
of the lever next to the roller.
5. Install the brake shoes with the webs against
the actuator lever and the pawl pins through
the web slots.
WARNING
Failure to correctly install spring in slot could pull
shoe away from actuating pawl and render brake
inoperative. Serious personal injury can occur.
6. Use a brake shoe return spring installation tool
to connect the shoe return springs to the brake
shoes in the slots nearest the backing plate.
7. Assemble the brake drum and drive shaft using
standard procedures.
Adjust DLM Brake
Equal alignment of the brake shoes is controlled
by the actuating lever. The only required
adjustment is through the connecting linkage to
the lever arm. The adjustment can be made after
the brake drum and drive shaft are assembled.
