Hs3 Hydraulic Brakes and Clutch
« on: November 15, 2017, 04:51:09 PM »
Finally got it figured out!!!

No more potentiometers for brakes and clutch, no more bloody hunting for the right springs and a shite load less 3D printing lol.

So here be the Handlebars with Front Brake and Clutch units to match other parts on the system. Still a work in progress but will be finished with new parts I ordered.



As you can see still got to test clutch but waiting on new parts. The Transducer for the brake is also gonna be replaced as it is only 150psi and getting 300psi units for clutch and front brake. Transducers fit behind the new all Ali back cover too.





Rear Brake is GSX-R1000 Rearsets with GSX-R750 Mastercylinder and 500psi Transducer.



Waiting on a 90 degree elbow to hide the transducer better and protect it.

So to some facts about using them. I used 10W40 motor oil instead of brake fluid as it works 100% and can be shipped where as brake fluid can not by all shippers. It sorks as I say just like brake fluid.

Found that when you calibrate in Windows, you can adjust how much presssure you want to aplly at the end point by simply not pressing too hard or as hard as you want. This makes it adjustable to how you use the brakes. Same in GPB and setting up for x360ce. This is such a welcome discovery as it really makes for a much better personal yet realistic feel for the first time. WOOOOOHOOOOOO!!!!

I think if it all works out, ALL Hs3 systems will come standard with full hydraulic units at very little extra cost, maybe an extra 50 quid on top which I think is bloody good.

Heres the current lineup of bars for the Hs3 system:



Just need Dorna to get back and let me know whats a happening lol.

Well thats all for now folks. Back when I get new parts and hopefully a vid to go

Looks good. Aren't clutches based on travel and not pressure though?

Many modern bikes have a hydraulic clutch, the clutch springs are what controls the clutch the lever just applys pressure to the actuator.

It should work if I figure it out for movement which is my only worry and then I will simply have a cable clutch lol

I'd tend to agree with teeds: even if a clutch is hydraulic, it's the displacement of the lever that matters.
So it's different with respect to brakes (where it's the pressure that matters).

Not saying it won't work of course.

Your quite right. I will have to design a special unit to give the right amount of movement before the biting point of the clutch. I have had bikes with hydraulic clutch so just have to emulate what I know lol.

But it will still be a first for a bike controller nananananana lol

Cool ! keep up the goodwork brô  ;), so you're using load cell ?

No Poum, I use Pressure Transducers. 300psi for front brake 500psi for rear brake. Need to play with clutch to get it right in feel.

That kind yes but you must be careful as many give bad resaults and fluctuate to much to be used

I used 10W40 motor oil instead of brake fluid

If you've put engine oil in your brake system i'd get it out quick, it will screw the rubber seals and hoses.

https://www.google.co.uk/search?source=hp&ei=Gs0OWtnXN8HDgAap_pGwCg&q=engine+oil+in+brake+system&oq=engine+oil+in+brake+system&gs_l=psy-ab.3..0.1717.5857.0.6064.28.27.0.0.0.0.85.1555.26.27.0....0...1.1.64.psy-ab..1.26.1553.0..46j0i131k1j0i46k1j0i22i30k1.37.Ba9OBAWu3oc

That seems a little contradicting information because if it's the mineral oil that causes the rubber seals to deteriorate then why is there also mineral oil based brake fluids?: https://en.wikipedia.org/wiki/Brake_fluid

Edit: H beat me to the post. Lol. Just what I was looking at there H.  ;D

Probably olive oil would work fine too :)

Just change the lines and seals.. Il get the name of the ones iv been using..  Tygon i think..... Never fade, never perrish.. All kinds of fluids
