The hydraulic handbrake in my rally car isn't working. Please help.

Any solutions? Have bled it. Even flow.
Pic related, it's the one i have.
Well being a linear system start at the front a work back. Recoil spring in master cylinder stuck? Plunger?
Don't mean to be a dick but do you know how to properly bleed brakes?
If the brakes are stuck we can assume either
A. The line is pressurized.
B. The caliper is locked up
C. The pads are rusted to the disc.
Have you driven it? Are the locked up under engine load?
Yes, i know how to bleed brakes. I'd be a pretty shitty rally mechanic if i couldn't bleed brakes.
Recoil spring operates freely.
Calipers work properly
Pads and disks are brand new.
Have driven the car several times, but i can't manage to lock the rear wheels at speed.
Current theory is that the guy who plumbed the system (not me or any of my guys) was really shit and didnt know what he was doing.
We have a rally this weekend and not enough time to redo the system, but we are going to replumb it and run the lines directly to the rear calipers and give the hanbrake it's own reservoir.
Is the handbrake plumbed into the brake lines or is it a parallel system?
Does your normal brake reservoir fill when you pull the handbrake? I guess I'm asking if it's flowing backwards.
Where are you rallying? I really want to build a Mazda 323 gtx Into rally car. Not much rally in the states though.
