<VV> Corvair content, Really! (brakes)

[William Hubbell]

Two dual m/c converted failures in 20 years?  I have NEVER had a failure in a stock Single m/c system.  I'm not saying it can't happen, but I think if you do your due diligence maintaining your brakes it is unlikely.  The way I look at it, a dual m/c system just has more things that can go wrong.  Besides, I think the best safety equipment is the nut behind the wheel, and the more you insulate that nut from the possible consequences of his actions (by installing ever more "safety" equipment), the greater the chance that "nut" will fail to do his job.

Of course, now they are putting large touch screens in the dash to further distract the driver.....

The answer "it's only a switch" came from one of those sources (larry claypool, I believe).  GM parts books list it as a switch as well, not a valve.  Thinking about how one works, it shouldn't be that tough to do a non-destructive test if you really want - the whole point of a shuttle valve is to cut off flow, so you should be able to test for that.

In both cases the pedal assembly was original to the car, one was a '65 and the other a '66.  The '65 is with the stock '69 m/c and switch, the '66 without.  I suspect there's a step that's more important to the installation than we think, I'll have to look and see what's in the Tech Guide on the subject.
