Wedge Modified brake proportioning valve for TR8

My bleeding brakes question comes from my adding braided steel lines and a modified brake proportioning valve to my TR8. Unfortunately my new valve seems to weep brake fluid from the side closest to the fender. The new valve also seems responsible for adding a rust color to my fluid (This I noticed as I bleed my brakes). I was a bit suprised when I received the valve as is was no cleaner than my old valve and the valve's openings were not sealed off? Needless to say the valve will be going back to Ohio? Has anyone else had trouble with a modified valve? Is the valve really a huge improvement? I'm a liitle reluctant the replace the valve again as paint was damaged by the leaky valve /bcforum/images/%%GRAEMLIN_URL%%/pukeface.gif
 
Previous owner of my car tried installing the same valve from the same supplier, it also leaked on installation, he reinstalled the orignal and it remains there today.
 
I installed that valve, no leaks, improved balance, no problems, happy with the results. Though I did have to clean it up a bit before I installed it.
 
The modified valve is merely a used valve that has been taken apart and had a shim installed. and then reassembled. It adds a little more biased to the rear. The TR8 is notorious for very little brake in the rear. I guess it was so no one would lock up the rears on a wet high speed turn in a panic stop. On the race car, I started by eliminating the valve and installing a Wilwood adjustable proportioning valve. I found that even fully adjusted to the rear, I still couldn't lock the rears up. My next move was to take it off the rear braking circuit and install it on the front. Once I started to dial down the front, I could finally get the rears to do there job. I would not advise this for any TR8 other than a race car. I would strongly suggest you get an adjustable one and substitute it for the stock one. Long story short. Rear brakes = bad. Modified rear brakes = a little better than bad. If you want good, then you might consider a Ford 8.8 inch rear end with vented 11 inch rotors and traction lock.
