So I might hook it back up to the bikes front brake system this time
but I was wondering about rigging up a general purpose hydraulic hand
pump for when I need to do such things.

It seems they do them fairly cheap on eBay and I'm assuming I could
use basic hydraulic fluid (less likely to take the paint off?) but I'd
need to make up some fairly high pressure adaptor hoses (25 bar)?

Is this something one can do diy and if so, do you need any special
tools for the joints etc?

I think the pumps come with a 1/2" male (looks tapered) outlet and so
I'd need a mating female to whatever I was working on, in the case of
most motorbikes, a 'banjo' connection of some sort.

I still use reusable fittings for repairs, they're good up to 200bar

The ferrule has a ******* thread which you wind on the hose, there are
different types depending on whether you skive off the outer rubber
first or not or how many steal braid layers the hose has, you then wind
the coupling in and the taper grips the hose to the ferrule.

They are deprecated by the hydraulics engineers whose code of practice
does not allow them to repair hoses but only supply a new hose with new
swaged fittings.
