Mechanical Hydraulic Brakes...

Fascinating. I don't think I'll ever have a need for a ultra-reliable, ultra-long distance bike... but if I did, I'd definitely consider putting these on them.

£285 seems a lot of money for a pair of calipers and dics and the the very small volume of fluid bothers me from a heat perspective ... but they look very nice.

Can someone explain the difference between these and the TRP HY/RDs?

About $100 more and 100g less for each caliper

Can’t help but think this type of brake is the worst of both worlds. A long run of standard cable to give a squishy feel and hydraulic fluid to potentially leak or get too hot.
If I wanted a very reliable brake for backcountry use I’d go for BB7’s every time.

That's pretty much what my LBS said when we were chatting about such things.

Mine have been fine on my bike and never had any issues with them - HyRd used for about 15,000 miles with at least one fluid change in that time.

Its much more powerful than the mechanical discs brakes it replaced never had brake fade on them - I have done the odd lakeland descent but i dont think i have done anything massively long on them.

Looks like the TRP has a much larger reservoir?

Weight aside then, I guess the TRPs might in theory be better as they might be able to handle more heat?

Won't the fluid volume on one of those be more than on a normal hydro brake as the master and slave cylinder are all in the same unit instead of just the slave....

I guess I'm interested as I want to use bar end (or no) gear levers and mechanical brake levers but they are affy steep!

No because a normal system has the capacity of the caliper, line and master cylinder. This one just appears to have a caliper and a very small reservoir.

Aye right enough... Of more concern is the lack of a bleed nipple. Its all very well saying they don't need bleeding (it voids the warranty....) but in reality your always going to have to do this at some point. Bleeding using two screw in ports is going to be a PIA and the chances of getting it air free will be remote......

In my experience I don't see the BB7 being more reliable than a full hydraulic, but definately easier to service in the field.

But this mix indeed seems like the worst of both worlds.

Contemplating Bb7's at the mo, has anyone tried the Gusset mechanical brakes ?

so everyone who does not use them keeps saying
In use its just a brake that is better than a non hydraulic cable pull disc brake that has never let me down in operation.

That’s what I meant.
But I can definitely vouch for the reliability of BB7’s having had a some in constant use for 15 years or so.

As mentioned in the article, these seem a better/cheaper option:

Think there is an old thread on stw about these. They seem alright and much neater than hy/rd's.

I had a pair. They were okay. I liked the fact that both pads moved rather than having the disc bend like most mechanical set ups but I can't say they ever seemed more powerful the BB7s.

Having ran several sets of BB7s and Spyres, I ended up plumping for a set of HY/RDs when I built my Tripster up a couple of years ago rather than going the full hydraulic route.

First year of riding they were great although have a certain sponginess to them which takes a bit of getting used to.

Whilst riding the Second City Divide last year I managed to overheat them, on taking them apart one of the pistons had seized. Only just got round to putting them back on the bike.

As others have said the Juintech do look good but the reservoir is tiny, be interested to see how people get on with them particularly with a heavy loaded bike :-/

There is still a lot to be said for BB7s :-bd

I rebuilt my ogre a couple years back and after some worthy recommendations from other Boners went for a set of trp spyke brakes. Theyve saved me on all sorts of potential disasters from the HT 550 and other Scottish epics to month long touring in France and Spain as well as hacking round Dartmoor. They match the burlyness of the ogre perfectly

I know they dont make sense from a fluid expansion point of view, but id stil like to try some. Shame they're a bit pricey really

Least expensive for the experience would be Juin Tech R1.
They were on the Fargo when I bought it and once dialed in worked very well.
Use Shimano pads and squeaky in the wet.
Front started to fade and couldn't find how to service it so replaced with Spyre and didn't really notice any difference except the Spyre didnt fade.
Zazen - nothing happens next this is it.
