    Why didn't replacing my master cylinder fix my brake problem?

    I have a 2000 gmc serria. When pressed, the peddle goes almost to the floor with very little resistance but just before it hits the floor it gets hard and a murmuring sound comes from under the hood until the pedal is released. I replaced the master cylinder (I'm sure I did it right)  and absoulutely nothing changed! What the heck?

    It really just sounds like you need to replace the brake pads and/or rotate the hubs.
