Drum brakes. There, I said it.
Because every time, it turns into a clusterM3. I'm doing the ones on my Falcon. Inevitably, I put something together wrong and have to take it back apart again. Then I get a new e-brake cable that winds up being several inches too short so will have to do both sides AGAIN because you can't get the cable out with all the brake crap in the way.
And when you complain about how much disc brakes suck, someone invariably pipes up about how SIMPLE they are and how they weigh less than disc brakes and they work just as good when set up properly.
