I work at a bike shop. I shorten hoses all the time. Sometimes I end up making a horrific mess just like that. After you do a few of them it will get easier, but it seems like it is sometimes messy and frustrating to me. Some brands are easier to work with than others.
@clyde thank you,I found this encouraging and decided to give it another go with just the top port.
Even though it didnāt fit, I managed to get it somewhat airtight and stable utilizing the port screws rubber washer.
I had screwed up baldly last time so there was a lot of air to pump out. After a patient attempt with pumping and hitting the cable I reassembled and the brake actually came āaliveā again after vigorously pumping the brake. Worse than before I messed up though.
I decided to air the brake another time, and this time it was actually better than before, but still unusable for a sudden brake.
I decided to ride it for a couple of days in hope more air will go to the handle (but changed my mind). I have no idea if will help much with another attempt (it helped), but at least I can prepare the brake for a downhill segment now with about 5-7 pumps.
I wonder if the point with the caliper screw (removable only) is to reverse the setup an have it as the topmost part and do the airing in that port insteadā¦ 
Not going to try unless that is the only way to get the air out.
Edit: On actual topic: Instead of bleeding my brakes I managed to bleed my fingerā¦
Update: This kinda works. My brakes actually works after yet another attempt, but the bite comes a bit late. I have officially overwon my fear for hydraulic brakes. I made a royal mess and pulled through.

Gotta love that pun! 
So after causing an oil pest and mutilating yourself your uni is now equipped with a standard length brake line and a sort of working brake? The big question is: was it worth it?
Confession time: Iāve successfully shortened brake lines and bled brakes in the past. But Iāve also made an oily mess when trying to bleed a brake (without success, I may add), and in addition to that I never got it to work again. Since it was a very cheap brake, the decision to replace it was an easy one.

That is an extremely big wound. I expect you called 112 right away.

Youāre right! If I got that wound here, I would immediately call 911 and get a $50,000 ambulance and a $3,000 bandaid.
Thatās the US way of life. My guess is in Norway folks swear, suck on the finger and then continue their activity.

Today I got my fourth flat in less than two weeks. I got a pinch flat on my 26ā dm on the 14th and 16th. And then a thorn in my 29er nimbus on the 16th and today. Despite my first ride on the 29er after patching the tube being under 3 miles I still got the thorn. I got three today actually but it seems only one reached the tube. I just knew wouldnāt have good luck today even though I made sure to stay on paved sidewalks and bike lanes. Oh well, thatās life and patches are easy.
Pinch flat walk on the 14th. It was the last mile of a group muni ride so I just carried it
Still I had a lot of fun on all my rides. Two group muni rides, one road ride with one other unicyclist, and then just a quick solo lap today.

Have you tried a higher end Kevlar reinforced tire? Does it make a difference? Iām mostly curious. That looks like a nasty tear.
Iāve had a single flat in five years of riding

Thatās an interesting shadow of your friendās uni! Do you have a pic of the actual frame?

I havenāt tried any fancy tires. Itās just a pinhole from a thorn. Itāll be patched. The bubbles might make it look more dramatic than it is. Given this tire seems to pickup thorns I might put a self sealing tube in it at some point. I have one in my 24ā that Iāve ridden regularly for years and Iāve never had to do a thing to that uni.
Prior to these I had one flat from a failed rim strip and Iāve had thorns in my 20" a couple times over the years. I thinks thatās all Iāve had on unis. The pinch flats are my fault for not riding muni enough to remember what tire pressure I needed. Iāll make sure to pump it up higher next time. The 29er and its thorns was just bad luck. Thereās a lot of long weeds with thorny seeds right now that various people have neglected to pull or trim.
I hadnāt noticed how the shadow looks. It must just be the angle of it and the brake hose making it look that way. Itās a normal steel 29er nimbus muni.
I get it, now. From the shadow I thought it was a construction similar to that of a typical crane - you know, the struts forming that zig zag pattern.
Will your rims support tubeless? Iām pretty rough on my b!ke, but I run tubeless and donāt worry much. Iām not yet skilled enough to muni.
Tubeless can wind up being a bit expensive if you have the bike shop do it, but it isnāt hard to do ā¦ if you have a compressor handy ā¦
Nothing I have is tubeless ready. I do have a compressor. Iām currently looking for a job so I can buy or build a new muni this year. Tubeless will be a consideration for that.
Natureās revenge on you not riding your uni often enoughā¦
