Currently in Buena Vista,CO skiing. When driving down the mountain, very steep grade, I was rounding a corner I applied the brakes and my driver side front tire started to wobble slowly at first then got stronger until it was uncontrollable. I let off the brakes and it finally stopped. I continued down the mountain only braking when I was going straight. Experienced no other severe wobbles. I did notice a very slight shimmy like I have felt in the past that I have attributed to my rotor I need to replace. I did replace brake pads roughly 5-6k mike ago. Thoughts? I still have to drive back home to Oklahoma.
