I was considering getting new hydraulic brakes for my mountain bike. Was hoping to find someone to help me put them on. It might be a long shot but I'd like to learn and not just pay the shop.
Watch some YouTube videos for the specific brakes you plan to buy, then you can see what's involved. Some brakes need special bleed kits if you plan to shorten the hoses. That said, they come already assembled and bled (in theory...) and ready to ride, so you just bolt them up and go. But the hoses will likely be a lot longer than necessary, so it's good to shorten them.
YouTube really is a FANTASTIC source for how to videos. Bikes, A/C units, washing machine, plasma TV's, you name it - there's videos that show how to fix 'em.
Yes, Shimano XT brakes are what I am going with. I have looked at some youtube tutorials. Pretty much every where i read says the hoses will need to be shortened. Just since I haven't done this before i wouldn't mind having someone else who has be there. Hopefully it will go smooth.
If your not comfortable shortening the hoses then don't worry about. Just bolt em on and go. Try to zip tie the lines so they don't flop around too much. Try to minimize brake drag by spinning the wheel and looking or listening for the rotor contacting the caliper. Keep moving the caliper ever so slightly till the wheel spins as freely as possible. I left them full length on my large frame Stumpjumper.
