Ok, we all hate the drum brakes and they suck compared to discs, but do they really suck that bad when used as a parking brake. Our Windstar has rear drums and they suck when I park on a sorta steep incline/driveway and set the handbrake. Well, they hold the van, but whenever we load stuff into it or when people get in and out while the parking brake is set, it makes a groaning sound. Like the brakes are gonna give any second. And I have to yank the handbrake up like all the way up until I can't pull it anymore in order to set it and it still makes this stupid groaning noises. I can even feel it move some! I tried the self-adjusting mechanism for the brakes and it stops way better in normal driving now, but it still sucks when it's used as a parking brake. Is this normal?
