Hydraulic cables
Hello. I have to remove my handlebar with integrated cable. Cables are already short, can I just remove the old barb and olive (so I can remove the nut) and install a new one on the same end? Or I have to cut the end of the cable anyways?

you're going to have to bleed it anyway so replace the hose if it's more than say 2-3 years old and as you say too short already.

DITTO, replace the lines.
BTW ----- Hydraulic cable is an oxymoron. Outside the bike world they're generally called hydraulic lines.
I get why we still call them cables, and wonder how many years (or generations) it will take for people to forget what they replaced and call them what they are.
This from someone who still "dials" phones, and calls "Avenue of the Americas" 6th Ave, even though it was renamed before I was born.

THe cables are still new. Currently I have installed an handlebar with integrated cables, now this handlebar I have to send back for a warranty replacement. The momentary handlebar is not cable integrated.

I translated from my language and that is correct.
You can still highlight my error without being a completely idiot and not answering the question at all.

No, you technically should not put the new parts on to area where the old parts were initially installed on the hydraulic line.
can you? Yea, but if it doesn't seal, then you'll have to obtain more new parts & cut or replace the hydraulic line.
do not use any sealant to hack it from leaking fluid nor drawing in air.

I didn't specifically address your question because that was already done in the preceding post.
In case it might have helped if I opened my post with "agree with above", consider it done.

He did answer: "DITTO, replace the lines." And prefixed his comment with "BTW"; surely that's enough of a clue that this was tangential to the topic?

To be fair to the OP that was an edit after my response to his original complaint.

should not need to cut the brake hose - but sometimes it is required (need to inspect)
having said that …
I’ve seen old barbs and olives used on old brake hose - and it worked fine … including two of my bikes

I'm lost here.
The OP says the line is already too short.
IME it's very possible to cut a brake line shorter, but I've never seen one cut longer.
It's possible that the OP misspoke since English isn't his language, but I'd want him to confirm whether he's asking about cutting the line and reusing the olive, or installing a new olive on the existing line which is likely crimped at the critical place.
The 1st is OK, but fitting an olive over or near the crimp left by an old one is much less so (though may be possible).

however if you are planning to install the "T" so as to operate 2 brakes from a single lever do your homework on lever piston size
you'll need to displace twice as much brake fluid if one lever is operating 2 calipers.

I didn’t even realize that hydraulic cable is a thing among bicyclists. I was not comfortable about the use of ‘hydraulic’ in it.
As far as the 6th Ave goes, I’m with you.

not 2 calipers, I was thinking about a second brake handle for just the back wheel . I want to mount on my rest bars , as a quick slow down or stop .

doesn't change the requirement to match the original piston~volume design, unless you dont care about the performance differences.

OTOH, if both levers are used together, they'd only need move half as much.

Beg to disagree. Assuming no leaks or excess hose flex, the main lever will activate a single brake equally, even if another lever is parked on the line. If the 2nd position lever is mismatched, it would only factor when that lever was used.
