Light, moderate to too much vibration on the front brake when driving downhill. I was driving downhill and I felt moderate vibration on the front brake. I was so scared that I have to release the brake hoping to stop the vibration. On the way back home, I have to drive another downhill and this time, I felt too much vibration on the front brake when I applied the brake. The vibration was too much that even the hood, I feel like it starts vibrating as well. When driving flat, the vibration will fade away or there is no vibration at all.
