- Rotate the switch counterclockwise, allowing the retainer to release.
- Pull the brake pedal rearward to full stop.
- While holding the brake pedal FIRMLY in position rearward, push the switch inward fully until the switch body contacts the brake pedal arm striker plate.
- Rotate the switch clockwise until a "click" is heard.
- The switch is properly adjusted when there is 7 mm (0.028 in) clearance between the end of the switch barrel and the striker plate on the brake pedal arm.
Important: Do not move the brake pedal during switch adjustment as this will cause an over-adjusted switch which could cause brake drag.
At this point the plunger in the switch should be pushed in.
