Brake Installation Instructions
1. With the vehicle on a level surface, set parking brakes
and chock drive tires to prevent the vehicle from rolling
forward or backward.
Failure to properly secure the vehicle prior
to commencing work could create a crush
hazard which, if not avoided, could result
in death or serious injury.
2. Prior to spring brake installation, ensure the spring
brake is caged. If the spring brake is NOT caged, refer to
Section 3.
Failure to cage the spring brake
before installation could prevent the
main spring from fully engaging the
foundation brake components which,
if not avoided could cause insufficient
braking force resulting in death, serious
injury or property damage.
3. Inspect the brake mounting bracket on the axle. The
bracket MUST be free from paint exceeding .01" (.25
mm) thick, debris, burrs, and cracks. The bracket MUST
also be flat to .02" (0.5 mm) (Figure 1).
4. Always mount the brake chamber directly to the bracket.
DO NOT add or insert shims, spacers, washers, or
reinforcing plates between the brake service base and
the bracket (Figure 2).
5. If the brake doesn't have a correct precut push rod, refer
to Section 4 Determine Correct Push Rod Length.
6. Install the clevis and jam nut onto the service push rod
if not already installed. The service push rod should
protrude NO LESS than one thread into the clevis body.

7. Before installing the spring brake, move the slack
adjuster arm in the opposite direction to the brake
mounting bracket by turning the hex (use a hand wrench)
until there is enough space for the push rod to fit in.
IMPORTANT: There could be multiple mounting holes on
the brake mounting bracket. Consult the
axle manufacture for the correct location.
Failure to determine the correct mounting
position could cause premature diaphragm
wear or service push rod buckling which,
if not avoided could result property damage.
8. Install the mounting nuts and washers. Torque nuts to
