Thanks Tom ! I was trying to answer another listers question in a rush - I like your answer to their question much better ! Bt.

None of the proportioning valves balance brake pressure left to right; only forward to rear, so L-R braking isn't affected by the valave anyways, and for all practical purposes, line length in (say) the front system doesn't matter; master cyl pressure equalizes left-to-right even with different length lines. And a lot of the valvey-looking blocks on the lower firewall in AMC cars are not proportioning valves; they are only brake-failure-light switches, that look for a big difference in pressure front-to-rear and make that dashlight come on. Some have prop. valves, some don't, depending on application.
