The rear wheels on our '07 Hyundai Accent hatchback have locked up.
This morning we got in the car, and when my girlfriend took off the parking break there was a strange thunk. As we began to drive forward it was clear that neither of the rear wheels were turning. The car has been parked on a bit of a slope for 7-9 days, but was working fine previously.
After chatting with some folks today, they recommended "backing up quickly and slamming on the breaks." I came home and gave it a try. As soon as I drove forward ~4' the right wheel began turning freely again. I turned the car around, backing quickly downhill about 25' then slamming on the breaks. I did that 3-4 times without freeing up the left rear wheel.
Can anyone guess what is going on? We've never had this happen before. I'm curious what's going on and whether it's something that a resourceful DIYer can fix?
