<VV> Corvair content, Really! (brakes)

[Lon Anderson]

I think the most important factor is to have your brake shoes properly adjusted.
My 61 Greenbrier has the original "manual adjusters" on it, and I would adjust them at every oil change (or when the parking brake would get a wee bit weak)...
THAT, in my opinion, is the major factor... well, that and the fact that people have grown accustomed to not pumping their brakes...
;-)
Later,
Lonzo

You have to bear in mind there are a number of people in the Corvair community 
and on this list) who have access to GM engineering drawings and many years - 
n some cases since the cars were new - of experience.  The answer "it's only a 
witch" came from one of those sources (larry claypool, I believe).  GM parts 
ooks list it as a switch as well, not a valve.  Thinking about how one works, 
t shouldn't be that tough to do a non-destructive test if you really want - the 
hole point of a shuttle valve is to cut off flow, so you should be able to test 
or that.
This makes twice (in about 20 years) that I've had a failure on two different 
ual m/c converted cars and both systems worked as advertised.  In both cases 
he pedal assembly was original to the car, one was a '65 and the other a '66.  
he '65 is with the stock '69 m/c and switch, the '66 without.  I suspect 
here's a step that's more important to the installation than we think, I'll 
ave to look and see what's in the Tech Guide on the subject.

 outside of the unit and someone made a statement that it is definitely just
 a switch but I don't know on what basis.  I don't really see how you could
 say for sure without seeing the inside.
