I know it fits as it’s a like for like replacement (and I also now know i shouldn’t have removed it in the first place 🤦♂️) but I can’t for the life of me get the barb into the hose. Please help.

If you have a bleed kit there should be a two-piece plastic block you can use to grip the hose while you tap the barb in with a hammer.
Heat the barb with a lighter (hold the fitting with pliers), hold the hose in a vice block, hammer in the fitting.
Magura sell something like a chain tool that holds the parts and pushes the barb into the hose but I find the hammer easier
It looks like you’ve got the nut with the barb and probably the olive all together and the hose seperate. It’s best practice to just use a new barb and olive every time, they’re not meant to be reusable and it’s ~$5 in parts.
The proper way to set a barb is with a [hydraulic barb tool](https://www.parktool.com/en-us/product/hydraulic-barb-tool-hbt-1) or equivalent tool. The less proper way is with [hydraulic tubing vice block](https://www.ebay.com/itm/164157133765?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=YmfTgeKrS5a&sssrc=4429486&ssuid=A25dLqwgRr-&var=&widget_ver=artemis&media=COPY) and a soft tipped mallet. I’ve done this a few times and it’s been fine.

Use hairdryer to heat up housing
Remember
The barb won’t go through the space between the yellow blocks whilst clamped
So it’s small readjustments and tappy tap tap with heat
What brake is that for?
I work with Magura brakes all the time at work. I use a barb press and it goes in easily. In a pinch, clamp the hose between the yellow blocks, hold the end you intend to insert in boiling water for a minute, the try to tap it in with a hammer. Super difficult without the correct tools.
