why they even use drums at all is a total mystery to me , discs are far more efficient and far easier to work on .. with the invention of discs the drums should have been dropped completely.. I don't get it , anything over 30 years old should be discs all the way around.

Because it is very easy to incorporate a cable operated parking brake in the design. Disk brake calipers with a parking brake unit built in (subaru used to do this on the FRONT calipers, the [children of unmarried parents]^*) are a pain to rebuild. Regular calipers are a 10 minute job to rebuild if you rush. I would rather do drum brakes than fight with disc calipers with parking brake klude-ons.
