HELP! Clicking noise when pressing brake in "Park" position on New 2011 Tundra

[Fuzz Toyota]

We just purchase a 2011 Tundra 4X4 5.7L V8. We have only put 600 miles on her and we put her in 4H today due to the crazy snow in the northeast. I then started hearing a clicking noise coming from underneath the dash when I press the brake pedal when the car is on and in the "P" (park position). I have never notice this before and it does it all the time now when I press the bake in park, in both 2WD or 4H.

Why is this happening? Is the something to do with the brake assist? Is this normal? I have never notice this before.

Ooops - didn't read your post closely enough and answered too soon.

Clicking you hear while pressing the brakes in "Park" is caused by the shift-interlock mechanism activating. Since you can't shift gears without the brakes depressed, there's a solenoid that must be activated by the brakes. When you press the brakes, that trips the solenoid and makes a click...but that also allows your vehicle to shift.
