Got new disc brake pads and the rear is pretty draggy.

Not sure if I can fix it or if I just have to wait until some of the material wears off. It's not slowing me down, much, but I can feel it and it's annoying.
Nice ride this morning though. Low 60s. Followed a woman, a regular commuter I see almost daily, then went into the woods for a while, came back out and caught up to the woman again.
