How easy is it to swap mechanical discs for hydraulic? Can I just put levers lines and calipers on?

Shop around, but there are some absolutely fantastic deals on Shimano Deore BR M615 brakes at the moment, about £60 for some of the best brakes on the market. Even cheaper if you get them from abroad, Alltricks.fr, hi-bike.de, probikeshop.com, Rosebikes.com. Just be aware that they will come euro setup, so front brake left hand. You'll probably need to shorten the hoses anyway, and can swap the hoses over when you do.

Do we do everything the opposite way round in this county? Never knew our cousins in Europe ran opposite.

The hoses are very fine bore, so the fluid's viscosity helps. You lose perhaps a couple of drops, but you can compensate for this by pushing the pistons out slightly, thus lowering the level in the reservoir. When you trim the hose, some fluid goes with the off cut, but when you reattach the hose and push the pistons back in, any air int he first cm of the hose is displaced into the reservoir. I've done at least half a dozen pairs now, and only ever had to bleed one brake after shortening and swapping.
Cool - doesn't it leak out from the reservoir as well though?

No, not if you're careful

I am thinking of going the other way!
After each winter trying to get stuck pistons out is a nightmare along with bleeding them to try and get them working again.
I look at the cable brakes on my road bike and wonder why would anyone choose anything else. So much simpler to look after and maintain.

Well thought I would finish off the MTB re build after the winter. All the rest is done, including BB, cassette, new chain rings, chain.
No brake fluid in the brakes, and the pads were knackered anyway. So I had taken them all apart, actually got the rear pistons out, cleaned and back in. Front piston still stuck, but decided to try and bleed the front and get the piston out.
So all ready, fluid in the syringes, bike wheels off, etc etc. go to unscrew the bleed screw on the rear and it simply turns to mush.
So the front has a piston stuck and no fluid. Rear has pistons that move, but a bleed screw that is not coming out and no fluid.
So I am going to scrap the pair of them and get a new set as the hassle of getting the going is ridiculous.
