RECOMMENDED BRAKE ADJUSTMENT PROCEDURE PER AXLE MANUFACTURER.
The proper clearance between the shoe and drum surfaces will be set up initially from our factory to assure
proper operation during the normal break in period. No further adjustment will be necessary until the vehicle
completes the recommended break in period of 200 miles (322 km).
Since all brakes of this type must be burnished or “run in” before their full e ectiveness can be achieved, the
MFG. maintenance manuals call for readjustment after the rst 200 miles (322 km) of operation. This usually
allows ample time for the burnishing to take place. Readjustments are not necessary for brakes tted with
self-adjustment features although periodic inspection is suggested.
•
Misalignment - from rough roads, pot
holes, excessive speeds and hitting curbs.
•
Tire Width - the wider the tire for otation,
the more uneven the tire wear.
•
Tire Air Pressure - to much or too little,
for the load.
•
Vehicle Hitch Height - if trailer is not level
with ground, axle camber is misaligned.
•
Maintenance - wheel bearing lubrication
and adjustment. Follow axle MFG.
instructions.
•
Brakes - uneven or misadjusted brakes
cause irregular brake activation.

The wear pattern and tread life of tires
involves many variables that the user has
control of, but DOES NOT
manufacture or design.
The following is a list of some causes supplied
by tire suppliers and axle manufacturers:
Clearances that are too small will result in excessive drag and overheating while too much clearance
can render the brake nonfunctional.
NOTICE
The following shows the correct adjustment for the MFG. brakes of 12 1/4” and 16 1/2” diameter.
