Most ECUs ground a wire to turn something on instead of providing 12 v. Probably your relay has 12 volts already to the solenoid and the ECU grounds the other solenoid wire. One might think it makes more sense to supply voltage than to ground it, but it generally is better to sink the current...
My ECU turns the pump on for about 10 seconds and then turns it off until the starter has the engine turning about 500 rpm and then it turns on the pump again.
You need to have enough clearance between the front and rear Clevis and the center section so that the bias bar can rotate the full extent. If you loose fluid on one side, you need to have the bar rotate all the way until it hits a stop. Then the other side can produce pressure. If you don’t...

Here is my analysis of the Tornado original brake system and the modifications that I had to do to it.
I have a relatively big cam and I don't generate enough vacuum for the servos to work. My maximum vacuum is 40 kPa. I have disconnected the vacuum with no change in braking performance. You...

I was with an...
