COE Question about hydromax on a ford

Ch***is is a '94 Ford F600 with a ***mins 5.9 and Lucas Gurling hydraulic E brake with the little yellow push/pull dash knob... The system worked fine when I parked it 2 years ago, I want to remove it because its reservoir and pump are in the way and from what everyone says online, eventually going to cost me an arm and a leg. My question is this, can I run a "T" on the return line of the power steering pump (integrated into the timing gear cover) to provide ATF to the hydromax brake booster? I think I read somewhere that the booster wants 3-5 bar or else the pedal will not provide enough force or will cause the pads and shoes to drag if too much pressure.
in regards to an emergency break, I think a line lock on the front brakes should hold it if ever parked on a hill, or even if you have to do a hill start (manual trans) with somebody in a prius a foot of the bumper...
Thanks in advance

 

I've never heard of this system, (sheltered life I guess) but here is some talk about it that might be helpful.

It does sound like at least some systems used one PS pump for both brake booster and Power steering

 

Thanks Steve, that's the same system. I would have just gone and done it if this was any system other than the brakes. I think the truck weighs about 4 tons in its current stripped down state. I cant imagine rolling through a red light with this thing, bad.
