II. Stop Lamp Switch Adjustment
1. Loosen the stop lamp switch mounting nut sufficiently to allow the switch to move forward and rearward in the adjustment slot.
2. Install stop lamp switch adjustment gauge (SA 9303BR) between the switch and the switch actuator pad on the brake pedal arm being sure that the plunger protrudes through the slot in the gauge.
3. While pulling up with moderate force on the brake pedal assembly, push the switch forward against the gauge.
IMPORTANT:
Hold the switch perpendicular to the actuator pad on the brake pedal arm to prevent the switch from rotating out of alignment when tightening the switch mounting nut.
4. Tighten the switch mounting nut.
Torque: 10 N-m (89 in.lbs.)
5. Release the brake pedal assembly.
6. With the brake pedal released and the adjustment gauge still in position, tap the gauge side-to-side:
a. If the gauge swings freely side-to-side, proceed to Step 7.
b. If the gauge sticks or does not swing freely, repeat Steps 1 through 6.
7. With the adjustment gauge in position, pull up on the brake pedal with very light force (approximately 2 lbs.) and tap the gauge side-to-side:
a. If the gauge swings freely, repeat Steps 1 through 7.
b. If the gauge sticks and/or does not swing freely, the switch is properly adjusted.
8. Inspect the brake system using the "Brake System Inspection Procedure" in this bulletin and perform necessary repairs using the repair procedures in the "1991-1993 Brakes Service Manual."
