I appreciate both points of view.
OK so today, I was able to fix the vacuum reference line from the fuel pressure regulator to the throttle body (Ported vacuum line). This should stop the fuel pressure from bouncing around and stay at a solid 32 PSI.
Second, I have a vacuum pump and fittings that assist in bleeding brakes/ clutches. I wanted to try and bleed the brakes again. In the Saleen, the brakes and they hydraulic clutch share 1 reservoir. I have a rubber plug that goes onto the reservoir and then I can put a vacuum on the reservoir to pull out the air. An online tutorial says to put 20 "bars" vacuum on the reservoir for 1 minute, then release the vacuum and pump the brakes (and or clutch) about 10 times. This process was to be repeated 3 times.
When I said soft brakes, I guess I should explain more. The pedal was pretty firm.... its just that I really had to mash down on the brake pedal pretty hard to get the car to a complete stop. Again, this was nerve wracking as I was only in 2nd gear.
Front brakes on a Saleen are 2 piston and the rear are 1 (Both are disc brakes). When the Saleen engine was in the car, it stopped on a dime..... Want to make sure I can still stop on a dime.
After going through this bleed procedure 3 times, I looked up where every fuse was for the brakes and ABS system. All were in place and all were still good (not blown). I am trying to think what else I can check before heading back out on a longer trip. I live in an area where there are no long open roads. For miles and miles in every direction, stop signs and traffic lights. This is why stopping is now my new concern LOL now that cooling has been taken off my mind :0)
I am going to do a little more research to see if there was something I disconnected that was sort of a power assist to the brake booster? Again, there was a fashionable butt load of electrical in that Saleen (almost all was not re-used). Everything is still there (which is why the engine bay looks so full of wires. Once everything is exactly dialed in (and works perfectly), then removing all of the extra wiring/harnesses will be the order of the day.
Found this:
The brakes on the 2005 to 2009 Mustangs are fairly standard, with discs both front and rear. The front calipers are dual piston, while the rear calipers have single pistons. Four-wheel anti-lock brakes are standard on all models, and
power assist is provided by a conventional vacuum booster.Vacuum-assisted (or boosted) power brakes were used in Mustangs until 1996 when the huge 4.6L SOHC and DOHC V-8 engines filled the engine compartment to capacity, making it impossible to fit a vacuum booster between the engine and inner fender. Thus, Ford went to hydroboosted power brakes, which consume less space.
Hydroboost gets its pressure from the power steering pump.Read more:
