I put this in another thread earlier today if the cars been washed or it's been raining the pads will bind. If you park the car overnight somewhere flat or chock the wheels and for Gods sake don't do a Brian Harvey (EAST 17) and run over yourself. Best would be get someone to release the handbrake and make sure the arm goes to the stop (red arrow) or see if there is a delay. the blue arrow is the 39mm spring used by the scenic I fitted one as I had one handbrake cable not fully releasing so the spring helped the both cables have now been replaced.
The handbrake is a mechanical mechanism which will operate even without fluid in the caliper. Now the original post must be for the latest Clio's so I don't know if the 197 caliper is fitted to the latest models.
Possible problems:
1. Handbrake cables adjusted to tight or sticking (disconnect push the cable by hand it should glide and the arm should sit at the stop when handbrake is normally released with the cable connected)
2. Caliper not working, operate the arm manually (remove the pads operate the arm the piston should move back and forward a small amount if not its the internals or piston sticking the boots do dry up and grip around the pad end neck of the piston which can make them hard to wind back causing them to twist and rip the boot which corrodes the piston also the old screwdriver wind back trick it can slip rip the boot same result.
3. Pads not moving freely when handbrake released (remove pads from guides should not slap about but very little pressure to move them vertically out or back and forward towards yourself use copper grease or lightly file the
PAD where it touches guide surfaces to correct it).
4. Slide pins not working, not allowing the carrier to float (get them working or replace them)
5. The cold weather and salt from the roads will leave everything a little tight until some heat or movement is created if you release the handbrake and your on a reasonable slope give it a few seconds, dab the brakes, wiggle your ass in the seat as long as they both release at the same time your OK if one goes before the other then instead of reaching for the keyboard reach for the tools or the phone, this is a thing a Renault specialist will fix and a dealer/normal mechanic will not care about unless something is hanging off. It's not the perfect weather for it but if you check all the brakes pre Dec the brakes will not be a problem come Feb, and another thought the front calipers could be binding also so that's something else to think about front and rear should be worked on twice a year to avoid problems.
Hope this helps someone
