    I went to drive my truck today and started it up and when I hit the brakes it dies sometimes and is hard to start back up. Is it a vacuum leak in the brake system?

    Sounds like you have a vacum leak.. is the CEL on?? If so the codes might help some.. Since the IAC and or else the TPS might not be communicating and increasing the idle when you hit the brakes.
