The parking brake lamp switch is bolted to the pedal mounting bracket and is actuated by a striker on the pedal.

To adjust switch, refer to Figs. 11-1 & 11-2.

The stop lamp switch is attached to the brake pedal bracket and is actuated by the brake pedal arm.

Adjustment (33, 34, 35, 36, 38 & 39 Series)

To obtain proper operation of the stop lamps, adjust the switch as follows:

1. With brake pedal in the fully released position, loosen switch locknuts and adjust switch until stop lamps just go off; then adjust switch until plunger is depressed an additional 7/64" (approximately three turns of the switch). Tighten locknuts.
2. Check stop lamp switch operation by applying and releasing the brake, making certain that stop lamps go off when brake pedal is in fully released position.

Adjustment(30, 31 & 32 Series)

1. With the brake pedal height correctly adjusted, insert switch into tubular clip until switch body seats on tube clip.
2. Pull brake pedal rearward until it contacts the internal stop. This moves the switch in the tubular clip providing proper adjustment.
3. Check stop lamp switch operation by applying and releasing the brake, making certain that the stop lamps go off when the brake pedal is in the fully released position.

A brake shoe adjustment is required only when new linings are installed or whenever the length of the brake shoe adjusting screw has been manually changed.

1. With the brake drums removed, position the drum end (inside diameter measuring caliper) of the Brake Drum and Shoe Gauge, Tool J-21177, to the inside diameter of the drum and tighten clamp screw, (Fig. 11-4)
2. Position the brake shoe end (outside diameter measuring caliper) of Tool J-21177 over the brake shoes as shown in Fig. 11-5. Rotate gauge slightly around shoes to insure that gauge contacts the linings at the largest diameter. Adjust brake shoes until gauge is a snug fit on linings at the point of largest lining diameter.
3. Remove the gauge.

An incorrectly adjusted brake pedal can hold the master cylinder piston from fully returning to its released position, which will result in brake drag or lock-up.

33, 34 & 35 Series

1. Remove the pedal return spring and the master cylinder push rod clevis pin.
2. Turn back floor mat and check pedal height (from floor pan to top of pedal pad). If dimension is not 7- 15/16" ± 1/8", loosen locknut and adjust stop screw. (Fig. 11-6) Tighten locknut and recheck adjustment.
3. To adjust the master cylinder push-rod, lightly push the master cylinder push-rod until it contacts the hydraulic piston.
4. Loosen locknut and adjust push-rod until clevis pin can be freely installed into the brake pedal, then shorten push-rod one turn for proper free play.
5. Tighten locknut and connect push-rod to brake pedal.

30, 31 & 32 Series

1. Turn back floor mat and-check pedal height (from floor pan to the top of the pedal pad at the center). Dimension should be 7-1/2" 1/8". (Fig. 11-7)
2. If dimension is incorrect, remove the master cylinder push-rod clevis pin. Loosen clevis locknut and adjust clevis until correct pedal height is obtained.
3. If car is equipped with Synchromesh transmission, adjust brake pedal height to match the clutch pedal height, within 1/8".
4. Tighten locknut on clevis and connect the push-rod to the brake pedal.

1. Release parking brake.
2. Be sure hydraulic pedal travel is within specifications before adjusting parking brake.
3. Adjust cables by first tightening equalizer adjusting nut until a heavy resistance is felt when rotating rear wheels forward, then loosen equalizer adjusting nut seven full turns. (Fig. 11-8)
