The bike will stop just fine, and I can lock the front wheel at 10mph with only using half the lever travel, but the lever comes all the way back to the bar if you pull it back fairly hard. The adjuster's set on number 1, btw, on number 5 it gets to the bar before the brakes are fully on.
I've ordered some braided lines as I'm pretty sure that these are knackered (nearly 27k on 8 year old stock rubber hoses), but my dad's also suggested that the master cylinder may be allowing fluid to flow back through it.
Any other suggestions?

Its possible that the m/c seals are in need of replacement. Sounds likely that you still have some air hanging around in there. Make sure there isnt any at the top of the brake lines where the banjo joins the master cylinder. You can open up the banjo slightly to bleed but I prefer to just make sure there is an uphill path right the way to the reservoir by leaning the bike to its left on the sidestand and turning the bars fully to the right.
Feel free to pop over to my place if you want a second pair of eyes on it.
