I'm designing a custom hydraulic hand brake I want to build next. It will be a pass-through or "in-line" system, which is to be installed between the master cylinder and the rear brakes by "intercepting" the pipe to the rear brakes.

Question: I guess I can use any "normal" hydraulic cylinder, like a common master cylinder (closing extra outputs) or better, a master clutch cylinder, which commonly comes with a single in and a single out ports. Is that correct?

EDIT: this diagram is from an existing pass-through kit. My question is solely IF a regular cylinder may do right, which I guess it would.

Theoretically what your proposing will work with two caveats.

The size of the compensation port. When the master cylinder is "off" there is a port that allows brake fluid to circulate from the system to the reservoir. This port is usually pretty small and trying to push enough fluid though it for the rear calipers may be problematic.

Calipers require a lot of pressure to operate. Cars even with just front calipers always have a power booster. Drum brakes don't require a lot of pressure and have a self actuating property that helps a mechanical hand brake operate. The cylinder needs to be properly chosen so it provides enough pressure for the calipers to actually hold the car.
