There should be a flare fitting on the steel line that comes apart there. The hose itself as shown in O'reilly's site is all one peice and is crimped together.

It's amazing how many people ask questions about BASIC MECHANICAL SKILLS involved with working on critical systems on a motorhome that will be carrying your family.If the OP was indeed so skilled as to not need tutorials,he certainly would not be stumped with removing a flex hose fitting.The whole point here is that if you don't know a basic hydraulic fitting,you probably don't know how to safely install the new one and all that you may encounter with the project.Harsh,but needs to be said.A man needs to know his limitations.

There should be a fitting, on the end of the metal tube that goes threw the frame rail, where you can put a wrench on & then another wrench on the rubber hose to take them apart.
Where the rubber hose connects to that metal tube, it can be a bugger bear to take apart & real easy to mess up the hex nut of the fitting using the wrong type wrench.
I would say, spray that fitting good with some PB Blaster & let it soak like over night first & then tackle it the next day.
Try to be careful as you can with the wrenches, not letting them slip on the hex nuts, cause if you do, you'll be down to a pair of vise grips trying to get it apart & then replacing that metal tube afterwards.
You might need another person, to hold the tube & hose to keep from bending them when you put pressure on the wrenches.

I've done a few of those hose replacements & the fitting where it goes threw the frame rail is the worst part of the whole change out to get apart.
Use some good quality fitting wrenches & it will make the job a bit easier.

If you are asking how to remove a simple hydraulic line,you should not be working on your own brakes. I know how the line comes apart.What is obvious about my lack of skills other than you want to play mechanic and not everyone agrees with the idea of unskilled people working on brakes? Hows this? You can get a chisel and a hunk of flat steel,take a big hammer and whack the hose until it's apart.Now get a saw and cut pieces of the remaining lines off until you get to something that looks familiar to you.Cit off there and get a bunch of adapters and some small garden hose and a handful of clamps and get to fabricating.Load all your friends into the coach for a test ride.
