I'm sure most already are aware of this, but seeing this thread I can't help but be reminded of the plot line that ran through several episodes of the '60s daytime soap "Dark Shadows".
Early on in that show Roger Collins is injured when the brakes fail on his '66 GT350H (rented for the purpose of filming a few scenes I would think).
Turns out his troubled son, David, removed the bleeder valve in an attempt to cause the crash.
Sorry for sidetracking a bit!
