For 16 years I lived out of town on a narrow gravel road. I bought a lot of beaters and parted them out and junked the remains. I can't count how many times I drove a vehicle up and down that road to check the condition of a trans or rear axle that only had a functioning E brake (or whatever you want to call it).

Those old Mopars with the E brake drum on the back end of the trans had great E brakes!
