Ive got a 07 gs with 1400 miles on it. Ive noticed over the past week that the front brake feels odd. As i apply pressure, it gives a "Slip Stick" behavior. Nothing happens, then the break tightens a bit and stops, and repeats with continued pressure. Its a far cry from a smooth application.

My first guess was brake fluid, but it seems nice and full. What should i look for next?   

bleed out the lines...kinda sounds like you have an air bubble.

07   Should still be under warranty.. Take it to the shop 

Yep, air in the line.
