Reply to "Brake Upgrade: Done, but Bugs to Work Out"

Hi Scott,
OK, so based on what's in discussion....
- you have the wilwood adj prop valve installed (btw I like this piece).
- you dial back the valve so you have fully open (unrestricted) rear brakes, and the fronts are still locking.
- key point here.... you essentially have a prop valve installed for no reason. (seriously... ;-) One typically installs a prop valve to dial back the rear brakes to ensure balance/stability with the rear not locking and therefore passing the front of the car (bad).
- suggestion: only have an inline valve, such as this 260-10922 willwood piece in the front circuit prior to the front circuit T block. Since you already have this one installed, I agree with the above post, just install the in line one between the master and the prop. (that said, recognizing the Gucci one will just be along for the ride.)
- Regarding the front side to side imbalance..this is not unique to the Pantera. I have experienced this with vintage stangs also. I did quite a bit of brake upgrade development work when I had Vintage Venom(now sold), and have seen this ugly beast before. Again, as mentioned previous by Doug, you can put a valve here too to balance the sides, or you can move the T-block to the center with equal lengths of tube to either side in an attempt to remedy it, this can help (keeping all mechanical irregularities of the functional performance of the two sides not considered, such as piston seal roll back, knock back etc etc).

Keep us posted....
