KELSEY HAYES REASSEMBLE

Assemble the park brake lever and wave washer to the new replacement shoe (Fig. 9).

Attach upper return spring between the two new shoe assemblies.

Apply a small amount of Mopar Multi-Purpose Lubricant or equivalent to the automatic adjuster screw assembly. Install adjuster with the two stepped forks facing toward the outboard side of the shoes (Fig. 10). The longer fork will be pointing to the rear.

Connect the lower shoe to shoe spring.

Expand the automatic adjuster so that the end of the shoes will clear the wheel cylinder boots. Position

the brake shoe assemblies on support plate and install holddown springs (Fig. 7).

Install self adjuster lever and spring. Connect park brake cable.

Adjust brake shoes so that they will not interfere with the drum installation.

CAUTION: Make sure the adjuster screw nut contacts the adjuster tubular strut.

Install the drums and pump the brake pedal several times to partially complete the shoe adjustment.

After adjusting the Parking brake cable (see Adjusting Parking Brake), road test vehicle. The automatic adjuster will continue the brake adjustment during the test.

VARGA REASSEMBLE

Assemble the park brake lever and wave washer to the new trailing shoe. Install retainer and close retainer ends (Fig. 9).

Install park brake cable in park brake lever of trailing shoe.

Attach trailing shoe, then leading shoe lower springs to shoes and anchor plate.

Position shoes on support plate and install holddown springs.

Install automatic adjusters. Left side adjuster has left hand threads and right side adjuster has right-hand threads. Do not interchange sides. Make sure adjuster is installed correctly. (Adjuster ends must be above extruded pins in web of shoe as shown in Fig. 3).

Install upper shoe to shoe spring. Ensure that the spring terminal ends are fully engaged in the shoe webs.

Rotate serrated adjuster nut to remove free play from the adjuster assembly.

Install the adjuster lever on the leading shoe pivot pin. Then attach the short end of the adjuster spring into the hole on the lever. Then install the long end of the spring in the leading shoe hole.

Connect park brake cable and adjust brake shoes so as not to interfere with drum installation.

BRAKE DRUM REFACING

Measure drum runout and diameter. If not to specification, reface drum. (Runout should not exceed 0.1524 mm or 0.006 inch). The diameter variation (oval shape) of the drum braking surface must not exceed either 0.0635 mm (0.0025 inch) in 30° or 0.0889 mm (0.0035 inch) in 360°.

All drums will show markings of maximum allowable diameter (Fig. 12).

Using suitable tool, remove grease seal from drum hub. Clean, inspect and pack wheel bearings. Install new seal (Fig. 13). See Wheel Bearings section in
