Hey guys and gals, I was driving to the store yesterday when my brakes started hissing at me. (I'd press the pedal and hear a hiss inside the cab). A quick google search told me that my brake booster was bad. I replaced it this morning, and no more hiss, but my pedal is still soft. As in, I can get the pedal to the floor with minimal difficulty. I took it for a test drive around the block and it still stops, but I'm wondering if I need to bleed the system for some reason. I didn't open the system up (although i did knock the reservoir around a bit), so i don't think I got air into the system. Any other ideas?
