8. Lubricate the S-Camshaft bearings with grease specified

in the Lubrication Table in Section 21 (Figure 48).

17. Brake Adjustment Procedure

1. Verify that the spring brakes are caged prior to beginning

adjustment procedure.

2. Adjust the brake adjuster until the brake lining contacts

the brake drum, then back off 1/2 turn.

3. Apply the service brakes using normal operating pressure

(average line pressure should be 90 psi, but not less than
80 psi). Check the following while brake pressure is applied.

• The optimum distance of push rod travel should be

approximately 1.5"-1.75" (38-44 mm) (Figure 49).

• Angle between the push rod and the brake adjuster

with brake applied, should be

95°-100°

(Figure 50).

• Brake lining to drum contact. A 0.010" feeler gauge

should not fit between the lining and the drum
contact area.

4. Release the air pressure from the service brake system

and check to see that all brakes release to the normal
relaxed position. If all brakes do not properly release, Refer
to Troubleshooting Chart in Section 22.

Failure to adjust brakes in accordance
with manufacturer’s instructions prior
to placing trailer back in service will
prohibit proper brake function which,
if not avoided, could result in uneven
brake system component wear.

5. Uncage spring brakes

.

Failure to uncage spring brakes in
accordance with manufacturers's
instructions after servicing is complete
will prohibit proper brake function which,
if not avoided, could result in death or
serious injury.
