Can the brake pedal be adjusted

The brakes on the car work fine but my brake lights constantly stay on because the brake pedal doesnt seem to come back to the default position it should when it's not being pressed. I can grab the brake pedal and pull it up to make the lights go off but I need it to cone back to that position on its own.

Is there an adjustment I can make anywhere?

And it has the factory drum brakes all the way around.

On a side note I bought disc brakes for the front from TheRamManInc.. but after I bought them I kept hearing horror stories that contradict his youtube videos about the ease of installing them so I havent had the confidence to move forward with that.

In the meantime I'd just like my brake lights to not be on all the time.
