Stop Lamp Switch Adjustment

STOP LAMP SWITCH ADJUSTMENT

^ TOOLS REQUIRED
- SA9303BR Stop Lamp Switch Adjustment Gage





1. Loosen the stop lamp switch mounting nut sufficiently to allow the switch to move forward and rearward in the adjustment slot (1).
2. Install Stop Lamp Switch Adjustment Gage SA9303BR (2) between the switch and the switch actuator pad (3) on the brake pedal arm being sure that the plunger (4) protrudes through the slot in the gage.
3. While pulling up with moderate force on the brake pedal assembly, push the switch forward against the gage.

IMPORTANT: Hold switch perpendicular to actuator pad on the brake pedal arm to prevent switch from rotating out of alignment when tightening mounting nut.

4. Tighten switch mounting nut.
Torque: Stop Lamp Switch Mounting Nut: 10 Nm (89 inch lbs.)
5. Release brake pedal assembly.





6. With the pedal released and the adjustment gage (1) still in position, tap the gage side-to-side:
- If gage swings freely side-to-side, proceed to Step 7.
- If gage sticks or does not swing freely, repeat Steps 1 through 6.





7. With adjustment gage in position, pull up on brake pedal with very light force (approximately 9 N [2 lbs.]) and tap gage side-to-side:
- If gage swings freely, repeat Steps 1 through 7.
- If gage sticks and/or does not swing freely, proceed to Step 8.
8. Inspect switch plunger:
- If 0.8 - 1.2 mm (0.03 - 0.05 inch) of plunger is visible between switch and switch actuator pad on brake pedal arm, switch is correctly adjusted. The height of the rounded crown of the plunger is equivalent to 1 mm (0.04 inch).
- If more than 1.2 mm (0.05 inch) or less than 0.8 mm (0.3 inch) of plunger is visible, repeat Steps 1 through 8.
