Ah yeah, you are not alone in having trouble with this. The lower caliper bracket bolt on the Murano is famously difficult to remove. It's very long and passes through the knuckle, so it's extremely prone to seizing up with rust and corrosion. Getting it loose often requires some serious persuasion with a long breaker bar and a good dose of a quality penetrating oil (like PB Blaster or Kroil). In tough cases, mechanics sometimes have to carefully apply heat from a torch directly to the knuckle around the bolt to break it free (be very careful with brake lines and sensors if you do this).
When in doubt, the service manual for your Murano will provide the two things: the torque spec for that lower caliper bolt when you reinstall it and the step-by-step procedure for correctly adjusting the parking brake shoes. It takes all the guesswork and risk out of a major safety-related job like this.
Better safe than sorry, right?
