shaking and wobbling

I have a 2001 Ford Taurus and am experiencing some problems. For the past few months, my steering wheel had been shaking both when I reached 50 mph or higher and also when I braked. I put new tires on it and the shaking went away driving it, however it still shakes when I brake. I also hear a wobbling noise coming from one of my front tires. Does anyone have an idea what is causing this?

warped rotor

either get both rotors resurfaced, then make sure you bed them in properly, or get new rotors and do the same. if you get new ones i recommend Brembo OEM rotors. most shops will give you even crappier ones then the cars come with. change the pads while your at it.
