when i come off the highway after some long distance driving and stop at a light, i get this intermitent popping noise comming from the front left wheel well. it only happens when i am applying the brakes. any suggestions to what it could be. my car also has a tendency to warp my front brake rotors very quickly, usually with-in 5K. all this started happening after i ran the front left wheel into a curb very hard about 2 years ago.
