Liberty Rear Disk Brakes for A-Body

I love this kinda stuff. It's true hot rodding. But I still have to ask why people thing a car that hovers around 3K pounds needs 4 wheel discs? I guess it's more of a want/bench racing kinda thing, unless you're doing something where they are actually necessary.
Rear disks do stop better when everything is new and works 100%. Add some dirt
grime and weather that always hits the back of the car ... so long 100% . Almost
every car with rear disks do not wear evenly, especially those with slider pins which
most cars use. Different story for same setup in the fronts almost always work 100%
and wear evenly.
