<VV> Re: Dexron in brake system ??

[P.H. Raker]

Hello, all,
     I had intended to lurk on the list for a while longer before
making a first post, but couldn't resist this one.
     Yes, Dexron and DOT-3 or -4 are both hydraulic fluids.  They have
many properties which are identical, but some that are different.  Many
of the experimental aircraft types use Dexron in their A/C brake
systems instead of the insanely expensive Mil-Spec stuff that must be
used in the brake systems of certificated aircraft.  Except for a few
additives, they are almost identical, and both are compatible with all
the materials of seals, hoses, etc.  I plan to use Dexron in the brake
system of the airplane I'm building.  I'm not, however, ready to use it
in a car.  I don't know that the seals and stuff are compatible.  I'm
certain that everything will work fine with DOT-4.  DOT-4 isn't that
much more expensive.  I don't want to trust my life to a possible
savings of less than $10 on something that's unproven.  It's risky to
try to second-guess the GM engineers.
     As they say, your mileage may vary, and this advice is worth what
you paid for it.
