NOTE:
Stoplamp switch may also be known as brakelight switch. When adjusting switch, hold switch perpendicular to actuator pad on brake pedal arm to prevent switch from rotating out of alignment when tightening mounting nut.
- Loosen stoplamp switch mounting nut sufficiently to allow switch to move forward and rearward in adjustment slot. See Fig 1 .
- Install stoplamp switch Gauge (SA9303BR) between switch and switch actuator pad on brake pedal arm, ensuring plunger protrudes through slot in gauge. See Fig 1 .
- While pulling up with moderate force on brake pedal assembly, push switch forward against gauge.NOTE: Hold switch perpendicular to actuator pad on brake pedal arm to prevent switch from rotating out of alignment when tightening nut.
- Tighten switch mounting nut to 89 INCH lbs. (10 N.m). Release brake pedal assembly.
- With pedal released and adjustment gauge still in place, tap gauge side-to-side. Fig 2 . If gauge swings freely side-to-side, proceed to next step. If gauge does not swing freely or sticks, repeat entire procedure.
- With adjustment gauge in place, pull up on brake pedal with very light force (2 lbs.). See Fig 3 . Tap gauge side-to-side. If gauge swings freely, repeat entire procedure. If gauge sticks or does not swing freely, proceed to next step.
- Inspect switch plunger. If 0.03-0.05" (0.8-1.2 mm) or less of plunger is visible between the switch and the switch actuator pad on the brake pedal arm, the switch is correctly adjusted. If more than 0.03-0.05" (0.8-1.2 mm) is visible, repeat entire procedure.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
