Some rally enthusiasts I know use a separate master cylinder that is plumbed in line with the rear brake pipes. When the (hydraulic) handbrake is
off, pressure from the main foot brake is transfered through the handbrake master cylinder. With the handbrake on, the second master cylinder
effectively shuts off the main brake lines, and applies pressure to the rear brake slaves.
The advanatge of this is that the mechanical system (e.g. cable) can remain in place to satisfy the legal requirement of two independant braking
systems (although in practice the cable seems to be adjusted so loose it doesn't really do much).

work on the same pipe and cylinders as the foot brake by some sort of valve. Exactly how is still a mystery to us but we are working to solve it.
Not much help.

If I remember correctly, the way that I/we used to do it was to splice a remote (no integeral fluid reservoir) clutch slave cylinder( it allows almost
un-restricted fluid flow when off) into the front to rear brake line at the appropriate distance from the hand brake lever and the connect a rod
between the two. Job Done.

Ok what you are looking for is something called a turning break. Dune buggies have been using these for years. They allow you to lock up the lefr rear
wheel or the right rear wheel seperatly via a hydraulic levar. Here are some different kinds.

I plan to buy a hydraulic handbrake and a line lock for an e-brake.
