Illustration 12 g03683296
Position parking brake drum (5) on a flat surface, as shown. Insert brake assembly (13) into parking brake drum (5), as shown.
Rotate adjustment screw (16) in order to expand brake shoes (19) and (22). Expand brake shoes (19) and (22) until the brake shoes are tight against parking brake drum (5). Note: It may be necessary to hold up brake assembly (13) in parking brake drum (5) in order for brake shoes (19) and (22) to expand without contacting the flange radius on parking brake drum (5).Note: Parking brake drum (5) should be tight enough to not slip off brake assembly (13).
Back off adjustment screw (16) by 12 notches (clicks).

Use Tooling (A) in order to pressurize parking brake actuator (2) to 12500 to 15000 kPa (1800 to 2200 psi) in order to extend shaft (29). Note: Do not exceed the maximum pressure of 25000 kPa (3600 psi) for parking brake actuator (2).
Adjust yoke (7) in order to achieve Dimension (L). Dimension (L) is 145 mm (5.7 inch). Do not torque nut (30) at this time.
Position lever (9) onto camshaft (11). Rotate lever (9) toward parking brake actuator (2) in order to remove slack in the system. Do not extend the brake shoes out to the parking brake drum.
Align the holes for yoke (7) and lever (9) by turning shaft (29) and lightly pushing up on lever (9) toward parking brake actuator (2).
Secure lever (9) on camshaft (11) by tightening bolt (10).
Apply Tooling (E) to the bore in lever (9). Apply Tooling (E) to the bores in yoke (7). Apply Tooling (E) to pin (8).
Install pin (8) and the cotter pin.
Tighten nut (30) to yoke (7).
Apply the brake by releasing the pressure in parking brake
