Brake Pedal Click
 

Just want to check and make sure this is normal. Before I start the car (Automatic Transmission) I press the brake pedal then the ignition button. There is always a couple of clicks in the pedal. This seems to only happen while parked or before start but then again while driving I usually don't have to depress the pedal hard enough to make it click like that. I have a 2009 model.
