Slack handbrake on Hyundai i30

My 2007 i 30 had this issue. Then didn't. Then did lol. It currently has the issue but I leave it a little maybe a few weeks and it eases off a bit. It's just started freeing up a bit so the car rolls by itself on a slight decline rather that acting like it has an automatic parking brake. It's done 113k miles and I can't be arsed messing around taking the rear brakes apart on my driveway. However thanks for the video as I wouldn't have know this was the actual issue until I took it apart. 219k miles hey... They are decent motors but that's really good going. Cheers mate

The same at kia ceed 2008, I have so much rust, but I clean and now it's working

Great explanation, thanks. Where does it fit?
