I have a '62 Sprint Speciale with a weird brake problem. After driving
for about 10 minutes, the brakes, or at least one wheel's brakes, seize
up and the brake lights come on and there is no travel at all in the
brake pedal.

After the car sits and cools down for a while the brake lights go off
and the car can drive. I haven't had a chance to jack it up yet and see
which wheel(s) is frozen, but I wanted to see if anyone had any ideas.
It would seem to be heat related, like a binding shoe overheating, but
that doesn't seem to explain the brake lights being on. And the master
cylinder, where the brake light switch is, shouldn't be getting real
hot. So.  .   .


Tim,

Odds are you are missing an aluminum and asbestos shield that fits
between the brake m/c and the exhaust manifold.  I couldn't swear that
the SS has one, but can confirm it was installed for this purpose on the
Giulietta Veloce models, so assume SS should have one too.  Manifold
heats the M/C expands fluid causing application of pressure to system
hence brake lights and dragging brakes.  Detrimental to the m/c seals as
well.
