I'll go check for some cracks right now. I did drive today I had no pulsing breaks but I went down the mountain the other way(there 2 ways down that aren't more then .2 miles difference). I think that my rotors might have overheated and then deformed. Would new/higher quality rotors fix this? Also is there a way to test the back end? I wonder if maybe the drums aren't taking as much of the brake force as they should. If someone could post a general method to check my brakes I would be thankful
