I have a six cylinder 4 wheel drive vehicle. When I step on the bake and then release the pedal I hear an air release sound. Sort of like a pnumatic sound on automatic doors. I have been unable to find any leaks in any of the hoses so I guess I am missing something probably simple. Any help would be appriciated
