"Clicking noise" in 1st and Reverse

When letting the clutch out and rolling into 1st and Reverse I have a pretty loud clicking noise. It sounds almost like metal hitting on something. It only happens when moving very slowly. Once i build a little speed the noise is gone. I know for a fact that my front right brake hangs up. Could the brake hangup be making that noise at the low speeds, and just be breaking free once moving fast enough?
