      They make a little plastic piece with a channel that sort of fits around and holds the cable in place (using pliers) so you can hammer. There’s also a sram barb driver/tool you can look up. I’ve also had luck holding the hose end with two hands and pressing the barb against something hard until it’s flush.

      Yes, you should recut to get a perpendicular cut. No, the slant doesn’t make inserting the barb harder, it’s just hard and that’s why presses are made for the job.

      This is one of those “even the cheap AliExpress version of the tool is totally fine for the home mechanic” tools. Spend $10 and get the right tool and you’ll be set for life.

      You need to put it in a vice with hose block/clamp then tap with hammer. Some axle jaws will work too like the Park AV-5. Put your olive on the housing first though.

      You can try heating the hose up with a heat gun or a hair dryer but the best way forward is to get a barb press. I have used a hair dryer and tapped it in once before and the hose ended up bursting. Thankfully it was testing the brakes in the garden and not on the trails. I learnt my lesson and got the right tool for the job. You can get presses fairly cheap and they normally come with a hose cutter.

      I used a heat gun to warm and soften the hose. Put the insert in as far as I could and pushed it against something solid to fully seat it

      It’ll work..okay-ish, but I’d recommend a recut so it’s a flatter end, which will make it easier to get a good seal when reinserted into the lever.

      I found a 3d model for a hose cutting tool. It takes a utility knife blade. I made one in PLA that works fine for a few cuts, but I’d pick a different material for a tool to use regularly.

      Are you trying to fit a BH59 size barb into a BH90 size hose?

      The cut isn’t pretty but isn’t why you’re having trouble. A proper barb insertion tool does help, but I have done plenty of these just using a hammer while holding the hose with pliers wrapped in a rag and they usually go in pretty easy.

      If you’re using a barb that’s designed for the wider ID hose, that will probably fight you going in. You might also struggle to get the olive to seat over it as well.

      I just started using threaded barbs for everything. Basically Amazon generic brand sram stealthamajigs. Trying to squeeze those barbs in sucks

      Id re-do it and Get the shimano brake hose tool, one of the best tools i own and is a pleasure to use.

      Cut should be as 90 degree as possible so the insert and olive form a nice seal around it. After cutting use a straight pick to set the hose back into shape, inserting the insert is meant to be difficult, but not that difficult if you got the right tools or grip strength. Whatever you do you need to keep the cable straight and not damage the insert itself, the rest is semantics.

      Yeah… It should be a horizontal cut, otherwise you might not be able to properly bleed the brake.

      I would re cut it. But it probably does not “have” to be. Could cause a problem maybe, will it cause one, maybe not.
