Lifetime leak proof warranty:Sounds fantastic, everything I want in a brake. As with everything though the judgement shall wait until it's reliability is known.
All those boxes are ticked. Except the performance is even better. Especially at the extreme end as DOT fluid doesn't gas out when it gets hot. So they don't need regular bleeding.The key think for me in regards to disc brakes are 1) how easy are they to set up; 2) how trouble free are they; 3) how easy are they do simple maintenance on; 4) and how much do they cost?
XT brakes are cheap, are ridiculously easy to set up, are trouble free and dead easy to do simple maintenance on.
They come with two sets of pads. Semi-metallic and sintered metallic. The semi-metallic is on par with the best brakes out there. The sintered metallic will scare most riders.Looking to replace my formulas for a new build and soon. Anybody know how much the sintered pads will cost? And when are they available?
They did say they can be flipped to work on either side 🤔One thing I don't understand:
On Shimano brakes the reservoir sits on top of the piston cylinder. In practice that means that if there is any air in the system it will find its way up into the reservoir and the brake will work perfectly.
On this new brake the reservoir is underneath the cylinder. With the cylinder the highest part of the system, any air will stay there and you've got mushy brakes.
Am I missing something here as it seems like a fairly big oversight?
That might be why they've designed it that way. By making the lever symmetrical the end user can put them on either side and Hayes cut costs by not having to make left and right levers!They did say they can be flipped to work on either side 樂
I think you're over thinking this. If any company knows about disc brakes, it's Hayes. I think they invented the mountain bike disc brake. It's a cutaway that's shown also, so maybe some part of reservoir is still at the high point.That might be why they've designed it that way. By making the lever symmetrical the end user can put them on either side and Hayes cut costs by not having to make left and right levers!
Shimano levers are less elegant looking than many, due to that lump of a reservoir sitting on top of the lever, but they have reasons for it and it contributes to the ease of use and reliability of the brakes. In use, the brakes will 'self-bleed' and are very tolerant of air in the system. You can run the brakes with air in them for years and no experience any ill effects. Contrast that with Avid brakes, which had a tiny reservoir and were a total pain.
On these new Hayes brakes the highest point in the system is here, were I've put the arrow, exactly were you do not want it. Sure, you can flip the levers but I'd rather have a brake that can tolerate an imperfect bleed and still function.

Like I said, maybe I'm missing something? I'm happy to be corrected but to be it seems to me like they've sacrificed reliability to save money and make a nicer looking lever.
