Re: Disc/Disc Proportioning Valve Help?

The front gets a lot of extra weight thrown on it during braking, while the rear end gets lighter during braking Given the same hydraulic brake pressure the rear will lock up first since there is the least weight on it. The proportioning valve lets you add some internal resistance in the rear brake line so the rear will lock up around the same time as the front.

An adjustable proportioning valve lets you dial it in with different loads.
