Brake failure - while coasting in "brake and release traffic", the brake pedal did not catch. looking down at my foot, i watched my foot floor the brake pedal and felt no brake pedal catch. looking up, my car continued rolling forward and hit the car in front of me. my car sustained over $2000 damage. fortunately, no one was hurt and the other car was not damaged. a month prior, the mini dealership had done scheduled maintenance brake work on my mini. because of this incident, i asked mini if it could have been an air bubble or something else related to the brake job. mini said no; any problem would have occurred a couple days after the job; not a month later. my car was towed to the mini dealership where they checked the brakes. mini said nothing was wrong. what could cause this? i'm concerned that my brakes could fail again , this time with more serious consequences, even death! please help! *jb
