Is the boot around the booster rod/brake pedal supposed to have holes in it for any reason? I tracked my hissing to a hole in the rubber boot under the dash around the brake assembly. I have never looked at any others to know if this is a problem or not.
BTW, my pedal is soft, but I just think I need to re-bleed my brakes.
