I read on this forum recently about someone swapping out their proportioning valve for a "T" fitting.
Does anyone know the size/thread count of the correct "T" fitting? Any fabrication required? |

I don't mean to hijack, but since everyone is already here and I've considered this modification I'd just like to hear some opinon on my situation. My car is not stock, it's a 71 six conversion (3.2) with Carrera calipers/rotors up front, and stock /6 brakes out back. It locks up the fronts way before the rears (I'm not sure if I can lock them up to be honest) and the pedal is not spongy but pretty high effort (not sure if I have 17 or 19 mm MC).
I'd like to increase rear brake bias, so I plan on first trying to adjust the valve. Is it correct that turning the adjuster counter-clockwise increases rear bias? Does anyone know how much can it be adjusted? Will it ever reach the equivalent of a T? Can that screw be backed out completely opening the system, or is there a stop? Does anyone know a sucessful setup for up a system like mine (with much larger calipers in front) short of a front proportioning valve (I don't like that idea) or dual MC / balance bar setup? Lastly, since I expect it's my best solution.. Anyone have any experience with balance bars in a street 914? Is there a kit perhaps? Thanks, and my appologies to the OP. |
