If the C2's parking brake is as useless as the C3 version, then I'd say the odds are very good that's what happened.

Yep, pretty much, I always leave it in gear on any incline.

What's bad about them?

I have one of those foot activated park brakes in the Torana and the ratchet system is worn so it tends to unsnap. I scored one dent in the nose cone when it came undone at a mechanics workshop, a friend tried stopping it using his foot on the front, luckily the tyre turned and it came to rest with the tyre right on the corner of the brick entrance but it knocked over a large oxy tank.

It happened rather quickly, not sure if the dent was from my friends foot or the tank. I think the tank could've been hit by the bumper bar rubber.

It could've been a lot worse.

They use a tiny little brake drum inside the rear rotor, they're almost useless on any hill.

Apart from the size of the drums and shoes versus the mass of the vehicle,  I think the main problem with the design is that there's insufficient mechanical advantage in the shoe lever system so the shoes can't be held hard enough against the drums, no matter how tight the cable is drawn from the driver's end.

It beat me how such a poor design could be carried forward from model to model until I noticed on reading various forums that many Americans simply don't use the parking brake. In fact, you'll read about Corvettes where the shoe mechanism has rusted tight in the brake-off position from lack of use.

I guess if they're mostly automatic transmissions driven on fairly flat roads, then the Park lock on the transmission does the job for them.

On the other hand, if you drive a heavy Vette with a manual transmission, the p#iss poor handbrake is not much fun when you're stopped at lights on a steep uphill climb.

I always leave a manual transmission car in gear when parked. And if I'm parking the Vette on a hill I'll face the wheels into the kerb for added safety.

There is a new after market device you can now buy that resolves the problem of the park brake on early model Corvettes :bag:

God damn have one of those systems on my Torana after I had a B/W diff put in it.

The previous handbrake at least worked great (when it was working) it utilised the same drum brakes. 

I agree these tiny brake shoes are hopeless, they barely hold it on a hill, you have to really stretch the cable tight.

I suppose that's a bit classier than the old standby:

And the 2008 Landcruiser STILL uses the design, and guess what??? They still don't work. I pulled the lever out of the floor at the boat ramp. (pulled the captive nut through the floor)

At one time I had   HJ75 troupe carriers ( that's what you get when you have 5 kids)
they had an excellent parking brake
How ever it takes two people to apply it
one to wrap the cable around the  tree  while the other operates the winch
or just leave it in low range with the engine off.

It's relieving to know it's not just us early year Corvette owners that has this problem
