Since changing out the booster, the brake lights occasionally hang up.
If I notice it, I joustle the fulcrum of the brake pedal, & it goes out.
Is there an adjustment or has the switch croaked?
Is it an easy replacement?
Try spraying a little WD-40 on the switch shaft and cycle it with your finger a few times, and if the switch is completely gone it isn't that hard to change out.
