Thanks again.. I'm pretty sure my pedal is tight. I can hear the power steering fluid flowing as I'm pressing the pedal in, then eventually the brakes bite. Could be that I need the restrictor fitting after all.

Could be a brake fluid bleed issue.

Could be.. but I pressure bled the brakes after first test drive and still got no bubbles, only clear fluid.

Maybe try a buddy bleed. I found that was necessary to get all the air out of a new master cylinder. With just a pressure bleed I had a spongy pedal on my manual brake setup. A buddy bleed pushed out a bunch more air and now they feel great.

It's not really a spongy pedal problem.. it seems to have almost no resistance until a couple inches in when the brakes catch and I have full stopping power. I really think its the setup of the hydro plumbing.

It sounds like what people complain about when they go up to big red brake calipers without upgrading the MC. The MC needs more volume for the bigger pistons. I didn't see what setup you had, just a thought.

That sounds logical.

Also, for bleeding, running some clear hose from the outlet over the side mirrors and into a bucked, will let you see for sure that all of the air is out.

I'm running standard 86 turbo calipers with a 02 mustang hydro and proportioning valve.

I have great brake feel with my Mustang hydroboost. No difference in brake feel when I upgraded from Turbo S front brake calipers to Big Red's.

I am using a tilton adjustable proportioning valve for the rear and have Turn 1 power steering pump.

Did you modify your PS pump for higher pressure? I also have a modified turn one pump. I haven't tested it yet with the BMW hydroboost, but it was awesome with my Porsche power steering.

Thought I would post a follow up to this build. So I've been driving the car a couple times a week over the winter.. trying to work out a few bugs. Still have an exhaust leak somewhere, haven't been able to track it down. The hydroboost is working great - I think it just needed some miles on it to work out all the air bubbles. I'm still running the stock GTO PS pump, mustang prop valve, and manual steering. No issues with the brakes at all. Only other issue is steering wheel vibration at highway speed and my alignment is off - I think I've tracked it down to uneven ride height in the rear.
