    Hayes Prime or Shimano XT

    I'm currently looking for new brakes to replace my Stroker Trails.
    1. Hayes Prime Expert (maybe Pro)
    2. Shimano XT M785

    Considering I had no problems with Stroker Trail I lean more to new Primes. I've read a couple of reviews and it looks like these brakes work great and have a plenty of power. BUT from what I've read here on MTBR new M785s are very good too.

    I often ride in winter at temperatures close to -10C. My old Stroker with DOT 5.1 had no problems through the last winter so I think Primes gonna survive that kind of a challenge too. And so the question is: If Shimano 785s with mineral oil gonna work in winter? I know that previous generation XTs tend to leak around pistons in winter (mainly because of bad seals). Plus I see some people have a leaking hose near banjo on M785s. And I don't like an idea of changing a hose on an absolutely new brake.

    Your suggestions?

    Shimano's are pretty damned great, they're such well honed, easy to work on brakes that just go on and on. Even when they do have issues, bleeding them is about as easy as bleeding the brakes on a car (ie, pretty damned easy!). Super solid lever feel, too.

    BUT, i do love my primes. I love the way haynes pushes forwards with innovation like the poppet cam, and i like to think that by buying their brakes i'm helping to keep that alive. Mine have worked brilliantly out of the box, super quiet, plenty of power to go one-finger with 160mm rotors, so much adjustability, and far better modulation than i had with earlier shimanos (although the new ones are much better).

    If you want utter dependability, shimano is the go. If you want to support a shed full of bright engineers, haynes all the way.

    Edit: I can't help you with the cold performance of anything though, it's far too tropical here.

    Lotsa winter miles on M765 and M775 at temps to -25C or so, not a leak to be seen.
