What kit do i need to shorten the hoses? Olives and what have you I mean.

When I did mine I just needed new barbs and olives (these ones), they didn’t need bleeding afterwards. 8mm spanner and a cable cutter did the job. Just be careful, keep the hose upright, and have everything ready to go before you make the snip!

That’s exactly the information I was after thank you.

You’re welcome!

Everything to do it came with mine. Useful shimnao guide somewhere shows you how to do it without a bleed.
