  1. With the brake pedal in the fully released position, ensure that the stoplight plunger is fully depressed against the brake pedal shanks. See Fig 1 .
  2. Fully insert the stoplight switch and the cruise control switch, if equipped, into the brake pedal bracket. Push the brake pedal forward in order to set the brake push rod into the booster.
  3. NOTE: Proper stoplight switch adjustment is essential. Improper stoplight switch adjustment may cause brake drag, heat buildup and excessive brake lining wear.
  4. Pull the brake pedal to the rear, against the internal stop. This adjusts both the stoplight switch and the cruise control switch. See Fig 2 .
  5. Inspect the stoplight switch for proper adjustment.
