Thumb Brake, winter project

If you run 2 master cylinders in the same circuit, the lower one will need its piston adjusted so far in that its compensating port is covered so when you apply pressure from the upper MC, it doesnt lust leak back out of the lower MC compensating port. You can also remove the reservoir from the lower MC.

Is this type of setup no good?image.jpeg

In this pic, the upper MC is flowing through the lower MC compensating port and it would have to be drilled out so it would flow more.
Compensating ports are very small maybe 1.5mm diameter and that would slow down the action of the thumb brake.

Realised last night, piggybacking 2 banjos on the pressure side of the lower MC wont work because when you operate the lower MC the fluid will just piss out of the top MC reservoir so the setup Slow bro showed is the only way it would work.

you can get a junction valve a number of the stunt riders use them, I order one for the gixxer but never got around to doing it as the lever proved too expensive
