Saw a car moving with back wheels not moving
Discussion
So the other day I saw a car moving down the road slowly making a horribly loud screeching sound of the tires and noticed
the front wheels were moving (FWD) but the back tires were locked and not moving. The tires were screeching until they stopped.
The first and only thing that came to my mind was that the driver left the parking brake on/up. Is that what it was? Does a parking brake
only lock up the rear wheels on a FWD car (hence why they use parking brakes for drifting?).
Anyways, I went up to the driver and helped them out acting like I knew exactly what I was doing. I told them it was their parking brake was
still on and to release it. She said it was released (don't know) but she ended up driving away fine. Maybe she released it I couldn't tell.

Not had anything to do with electrically operated parking brakes but with the exception of some Land Rovers (incl my RRC) where the parking brake operates on the propshaft all the cars we've had FWD & RWD the parking brake has only ever been on the rear wheels.
So very likely that was the issue.
It MAY also have been faulty & sticking on. (BTW a common issue with caravans where the shoes will rust to the drums which is why you are better chocking their wheels instead of leaving the brake on. Can be an absolute pig to release. Boat trailers where the wheels are immersed can be the same.)

Yes, parking (handbrakes as we call them, e-brakes in the US) generally only work on the rear wheels except for some older SAABs, whether F/RWD pretty much all are rear only.the front wheels were moving (FWD) but the back tires were locked and not moving.

The other common reason for this is seized on shoes as above & this can then release after a shock while driving so could have been this.

A few Citroens, too.Wouldn't be surprised if there are the odd others.
It sounds like the handbrake mechanism had seized on at the wheels, so released the brake lever wouldn't make any difference. Handbrake mechanisms do tend to deteriorate over time, due to being located right in the firing like of muck and road salt. Some cars this year have spent months sitting there without turning a wheel, so quite a few will have slight seizing issues. I tend to leave the handbrake off on my old Land Rover (which has a transmission brake) or my car to stop them seizing on.
My old Calibra Turbo had that horrible old handbrake design with a set of drums built into the disc brake hub, thank god that pretty much got abandoned.

Yep, a set up like this is far superior to having the rear pads acting on the discs as a handbrake because as the disc cools and contracts the obvious happens and you end up getting up in the morning to find that your Mondeo has rolled four feet forward and blocked the road...
...And that, typically, was the only time I left an old Ford out of gear...
