What to do if your brake pedal won’t work?
Once the car shuts off there is no longer a vacuum source. It won’t take long for your brake pedal to go stiff after this point. That being said I would start at the starter, get the car running, and if the pedal is still stiff at that point, then take a look at the brakes. Jun 08 2008 29690
