We are now all three on the same page...Anyone who knew his ride would
not try that with a Camaro.  You are taking a knife to a gunfight.

Does running Beltway 8 in Houston qualify??  Competitors there regularly run
in excess of 90MPH. ;>)

I roadrace an AS camaro (SCCA), and have both '94 and '98 street Z28s
at one of the worst tracks, brake-wise, in the U.S.: Blackhawk
Farms Raceway.

It sounds like what you experienced was brake fade (ie. solid pedal,
pressing down hard, but vastly reduced braking force).  If you had
a soft pedal, or it dropped to the floor, you were experiencing
fluid boiling (exactly the same symptoms as air in the line).

Fade is caused by overheated brake pads.  The material that
the friction material together becomes so hot that it begins
to boil.  The gasses come out at the surface of the pad, and
get between the pad/rotor contact area, greatly reducing the
friction between the two.

In the old days, you would be told to use cross-drilled rotors.
This gives the gasses emerging from the pad surface somewhere
to go.  These days, pads are available that work at much higher
temperatures, so cross-drilled or slotted rotors are mostly
for "show".  Performace Friction Z pads will probably be
a good track/street setup.  Porterfield, and Hawk Brake are
two other manufacturers who make race and street/race pads
that will work on your car.

If you are really serious about this addictive sport, I would
look at the www.fbody.org website.  There is probably a "how
to" to upgrade your single piston, cast iron caliper setup
to the 12" dual-pistion aluminum PBR calipers (this is what
I use on the race car...and is essentially what was the
seceret "1LE" option package on third-generation F-bodies
(camaros/firebirds).

Getting some 3-4" aluminum, flexible dryer ductwork and cobbling
up cooling air to your rotors is another cheap way to keep the
brake temps down.

Next time out, though....try to work on that "red mist" in your
eyes and pay more attention to how your brake pedal feels...
and remember, if you can't afford to push it off a cliff,
don't take it to the track...
