Default Bad timing...

Anyone know if it's possible for a brake to hang up and not release,
resulting in advanced wear like this? Or should I keep blaming Mary
for riding the (right) brake?



Yes. In cars, this is often caused by the caliper rusting.
That's caused by a) road salt b) water in the brake fluid.
Hence the recommendation to flush the fluid every 2 years.

I've read both the 'rotor runout' and seal material explanations
for retraction; I suspect there's some of each. In any case, with
no pressure/drag - i.e pads skipping along; there's very little if
any braking action.

And a few cars, such as Corvettes in the middle 1960s, were reputed to have
springs inside the calipers so that the pads would not retract. This was
supposed to keep the pads and disks cleaner and drier, with only a very
slight increase in the rate of wear.

I never owned one and don't know how well it worked.
