How much should I tighten my brake disc's? I think I tightened them t 150 lbs of torque but should I go 180?? Should I use the braker bar to tighten them by hand?

Are you referring to the calipers? I'm not aware of discs needing to be tightened to a specified torque...

The axle nut that tightens the rear disc's.

Yikes! You obviously don't know what you are doing!

There is nothing that tightens brake disks (rotors) other than brake pads when you apply the brakes.

You need the torque value for the rear axle nut, which I'm sure someone will
provide.

I can't imagine what you're tightening to 150lbs. Maybe we don't fully understand your question.

Yeah, use the breaker bar. The real long one.
