Since H2O is one of the most common molecular element structures, these will only become hyper-über-whore bath expensive demanding the most pure of metals. Plus any contamination entering the system will likely swell and clog the circuit, as opposed to oil being able to isolate any loose sediment.
One DH run (as they claim) to test boiling-points does little to sway me.

And some brake manufacturers will market bottles of "bake specific h2o" for $16 and a proprietary bleed tool for another $45.

Or, it'll be water from natural brake springs - bottled on Mars though.

My local source for brake springs...I think the glycol is already included...

These spring water will be much more special-er. "Bottled by scantily clad Iguanas, having crashed their Italian-jobbie spacecraft in 1866 after sicking-up Rootbeer on the C-Deck!"

...that last part an attempt at showing humor, but I'll stick with my last model HOPE brakes.

i tend to try and be frugal; i would go for the $6 asparagus water:

Asparagus water filled brakes is still a better concept than this Padlock grip bullshit.

 

[StiHacka]

Water, asparagus --> piss brakes.

1. create asparagus piss brake fluid
2. market for exotic smellz

Sounds like we have a new flagship product for our Absurd Monkey Components brand!

can we please talk about this?

Water has an affinity for absorbing gas and by increasing the pressure of water you increase that affinity. Just go to any water faucet and pour yourself a class of water and let it sit overnight. It'll be full of gas bubbles in little time.

Also, a common method for degassing water is by running it through a silicone coil within a vacuum chamber since the tubing is gas permeable. Seems to me that by introducing water into a pressurized system, you're at risk of doing the complete opposite of that.

I'd be happy to be proven otherwise, but my gut is telling me that they should shelve this before sinking much more development time.

Comment section on WTB essentially doubling down = Ouch.

These brakes were invented by a 21 YO guy, if I recall correctly. He has been showing them around in EB and IB for some years now. They previously used mineral oil, and the reviews they got were much less than stellar (see PB and MTBR for examples). I guess he's still stirring the pot to see if he can milk that old cow a bit more by changing to a water-based system.

Still, water might work, not in those brakes, but maybe something else.

It's not Chocolate Milk...

 

[Lelandjt]

Well, just because it's been their approach for a decade doesn't mean it works. Do you know anybody that runs WTB tires? Me neither.

I've been loving their Breakout tire and I've seen a lot of other WTB tires on the enduro circuit this year. Their Tough Casing hits a perfect balance between weight and durability. I can run much lower pressures than with Maxxis Exo. That alone could be where the improved grip comes from but I'm also impressed with how fast the Breakout rolls.

While true, the sugar and fat in the milk would make it corrosive and kinda chunky after a few heat cycles.

I think water and some water wetter would be the best choice for a first attempt.

 

[pizza diavola]

Water wetter? Is that what's supposed to be added to mix up a package of dehydrated water?

It's from the power sports industry. Adds lubrication and anti corrosion properties for when you can't run antifreeze, like race tracks.

 

[junkyard]

Water wetter is also a bubble less soap. Breaks the surface tension so the water touches stuff more and transfers heat better. I used it in every radiator.
