brake proportion valve

[gumba]

In a couple of threads I see references to the p/v. Where is this located?
I did the VCI upgrade a few years back (930 calipers f&r, 23 m/c, etc.)and nothing was mentioned about changing the p/v. Under very hard braking (at the track) my fronts will start to lock up. I thought of installing a proprotion valve.

Just remove the valve and go with a direct line to the back brakes by either running a short piece or the whole line itself. I had a similar problem with mine until I removed it. The funny thing is that now my car stops better, but I have to be carful about front wheel lockup even more since the rears are biting better.

Gumba,

I just did this two weeks ago, so I can show you how I replaced mine the next time we're in the same place

I just fashioned a brake line that goes from the MC to the coupler on the far side of the stock P/V. It was pretty simple.
