Brake Hose won't unbolt from rear caliper

[Fiat88]

I'm having a hard time breaking the rubber hose off the driver side rear caliper. The rear passanger side one came off with no issue. I've tried WD-40 and Freeze off and tried using hammer and wrench to break it free but no go and it has the copper washer. Any other suggested method I could use? BTW, what's the torque rating for tightening the rear rubber brake hoses to caliper?

On some of my more difficult ones, I cut off the hose so that I could use a 6 point socket and air impact.

Good idea may try that, just hope it comes off!

Ok got it off! I cut the hose and then use the close end of the wrench with a few hits with the hammer.

I'm up to my last hose to replace and its the middle rear one which is given me trouble. I got the flare nut end off but the end which goes into that three way connector is being stubborn. May cut it like I did with the last one I replaced.

I like to use heat and PB Blaster on the hoses and bleeders. Even a little propane torch helps
Also I like to save an old hose and plug it. Then when ever I have a brake line disconnected I connect the plugged hose to the line so master cylinder does not gravity bleed itself dry.
