Pull brake pedal fully rearward until no clicks are heard from switch. Release brake pedal. Pull brake pedal fully rearward again and release brake pedal to ensure no clicks are heard. Note switch plunger where it contacts brake pedal arm. Plunger should protrude from switch so notch at end of plunger is just visible. If plunger (beyond notch) is visible, or if notch is not visible, repeat adjustment. Ensure brakelights do not stay on with brake pedal at rest (unapplied).
