damage to the brake linkage.
NOTE: Adjust right and left brakes individually.

brake handle linkages.
2. Adjust left parking brake pull rod until brake rock
shaft lug is perpendicular with the bottom edge of
the frame rail.
3. Readjust and reconnect clevis for parking brake
handle linkage.
NOTE: Approximately 12 to 13 lbs of force at the
top of the handle is needed to apply the single
brake.
4. Reconnect right parking brake rod.

SOLENOID TEST
1. Disconnect solenoid from engine and briefly crank
engine.
2. Leave key ON. Fuel solenoid should be engaged
(pushed out).
NOTE: If fuel solenoid will not engage, check inline
fuse. If fuse is OK, test the solenoid in this manner:
a. Disconnect wires from solenoid terminals.
b. Set a multi meter to X 1 ohm scale.
c. Connect leads to “Common” and “Pull” solenoid
terminals; meter should indicate 0.1 ohms.
d. Connect leads to “Common” and “Hold” sole-
noid terminals; meter should indicate 10 ohms.
NOTE: If you do not get these readings, or one of
the circuits reads “OPEN”, then the solenoid is
defective and you will need to replace the defective
solenoid.
