(3) Insert a thin screwdriver in the adjustment
slot and push back the adjustment lever. With the
lever in this position, back the star wheel adjustment
off approximately 10 notches. This will eliminate the
possibility that the brake is at full adjustment, and
can be adjusted no further.
(4) Remove the screwdriver from the adjustment
slot.
(5) Watch the star wheel through the adjustment
slot, while a helper applies the brake pedal. As the
brake shoes apply, the adjustment lever should move
downward, turning the star wheel. A definite rotation
of the adjuster star wheel can be observed if the
automatic adjuster is working properly.
If the star wheel does not move as indicated, the
brake drum needs to be removed and further inspec-
tion of the rear brakes is necessary.
(6) If the star wheel is operating properly, readjust
the brakes. (Refer to 5 - BRAKES/HYDRAULIC/ME-
CHANICAL/BRAKE
MENTS).
(7) Reinstall the adjustment slot access plug.
(8) Lower the vehicle.

BRAKE LINES

DESCRIPTION - BRAKE TUBES AND HOSES

The brake tubes are steel with a corrosion-resis-
tant nylon coating applied to the external surfaces.
The flex hoses are made of reinforced rubber with fit-
tings at each end.

OPERATION - BRAKE TUBES AND HOSES

The purpose of the brake tubes and flex hoses is to
transfer brake fluid pressure, developed by the mas-
ter cylinder to the brakes at each wheel of the vehi-
cle. The flex hoses connect the chassis brake tubes
which are mounted to the vehicle's underbody to the
brake at each wheel, allowing for movement of the
vehicle's suspension.

INSPECTION - BRAKE TUBES AND HOSES

Flexible rubber hose is used at both front and rear
brakes. Inspection of brake hoses should be per-
formed whenever the brake system is serviced and
every 7,500 miles or 12 months, whichever comes
first (every engine oil change). Inspect hydraulic
brake hoses for severe surface cracking, scuffing,
worn spots or physical damage. If the fabric casing of
the rubber hose becomes exposed due to cracks or
abrasions in the rubber hose cover, the hose should
be replaced immediately. Eventual deterioration of
the hose can take place with possible burst failure.
Faulty installation can cause twisting, resulting in
wheel, tire, or chassis interference.
PADS/SHOES - ADJUST-
The steel brake tubing should be inspected period-
ically for evidence of corrosion, physical damage or
contact with moving or hot components of the vehi-
cle.
