3.27. Assemble the brakes by reversing the shoe 

removal process. See Figure 3.27.

NOTE: 

Apply a small amount of white lithium 

grease to the metal-to-metal contact points as 
the brake is assembled.

NOTE: 

Measure the bore of each drum, then set 

the adjuster to bring the brake shoes for that 
drum out to slightly less than the I.D. of the 
drum. If a brake shoe and drum caliper is not 
available, a tape measure will usually provide a 
measurement that is close enough.

3.28. Install the brake drum without the wheel using 

two of the five lug nuts. Install the lug nuts 
inside-out, so that the flat side is against the 
brake drum. See Figure 3.28.

NOTE: 

Rotate the brake drum as the lug nuts 

are tightened to insure that it is centered.

3.29. Adjust the brakes as described in the “Brake 

Adjustment” section of this manual. 

3.30. After brake adjustment is complete, perform the 

operational test as described in the “Visual 
Inspection and Operational Test” section of this 
manual.

BRAKE ADJUSTMENT

4.1.

If the brake adjustment is being performed after 
other

 brake service

, such as brake shoe 

replacement or brake cable replacement, begin 
with the “Brake Shoe Adjustment” step. Con-
tinue with the “Brake Linkage Adjustment”.

4.2.

If brake adjustment is being performed as part of 

scheduled maintenance 

or because of a

 per-

formance complaint

, begin by performing the 

steps of the “Complete Inspection” section of this 
manual up through the point of brake drum 
removal, then proceed from the “Brake Shoe 
Adjustment” step.  Continue with “Brake Linkage 
Adjustment”.

BRAKE SHOE ADJUSTMENT:

4.3.

With the brake drums removed, make a visual 
inspection of the brake shoes and the compo-
nents that actuate them. See Figure 4.3.
