View Full Version : Wedge TR7 50/50 Proportioning Block

Was looking for a boast in rear wheel pressure for my TR7 and ran into the son of the Wedge Shop at TRF summer party and he suggested this part. How does it work like the internals of it? Looks to me like just a aluminium block with a drilled and tapped inlet and 2 outlets. Also does anyone have on their car that remarkably improved their braking?

I have it on my car because my original was all jammed up. The brakes seem to work fine. Or I should say a lot better than before because the rears stopped working all together, which prompted replacing the original valve.

Thanks Todd I do remember that tread and do have it saved. Just wanted to know if the block was some type of a proportioning valve or a expansive 3 way connector. I am soon going to try teeing them and seeing what I got for braking power. Certainly don't want a lock up situation on the rears. Thaks for you help.
