2004 A4 Brake light
 

Just had new brake pads installed and rotars resurfaced, now the brake lights activate (when I am not with the car) and by morning the battery is dead. I "imagine" there is some type of adjusment to a sensor that needs to take place after replaciing the pads,but the shop who serviced the brakes does not know.
The brake lights come on with a lightest of touch to the brake pedal, this is way to sensitive...any help out there?
