Over the past few week I've notice more and more that when I get into my car from cold and go to drive away I'm getting a clunk from the rear brakes sticking on. I've experienced this before on much older cars and I was advised that it was from old brake fluid but it seems odd that its happening in my i30 when its only 2.5 years old and 30k. I never leave the handbrake on while parked either. Has anyone else experienced this?

Haven't tried this with my i30, but it has nothing to do with the brake fluid.
The rear brakes on the i30 is discbrakes, but the handbrake is drumbrake (inside the disc).
This time of the year, if you don't use the brakes much, or if you allways brake very carefully, there can be moist between the brakepads and the disc. When it is cold/frost, this moist will "lock" the pads to the disc.
Unfortunately the design with handbrake inside the brakedisc means that you can not clean the rearbrakes by using the handbrake while driving.
If you make sure to brake hard the last times before entering home, I'm pretty sure you can avoid this issue.

I take it there is no issue regarding the car drifting away say on a slight incline.
Do you leave in gear?
Has anyone else experienced this?
When damp I have had the discs becoming covered in a "rust" coating which causes a squeal when I first apply the brakes.

Nice post Asterix :goodjob:

I had to read asterix' post couple of times to be sure I understood what he was getting at (I'm old and slow :-[ ) but I think he's on the right track.
Some things to consider.
Are you parked outside or has it been raining a lot lately?
Even though you've only done 30k, get someone to look at your rear brakes (or do it yourself if you are qualified). Make sure you haven't got premature wear on one pad (which might indicate a sticking caliper). In case this is a recent problem and the wear hasn't yet manifested itself, take the car for a drive enough to get some heat into the brakes (don't use them excessively, just normally) then, before they cool down jack up the rear and make sure both wheels turn freely. Sometimes a caliper piston /seal will bind on lightly when hot.
If everything is OK, what you describe isn't uncommon and it may go away when weather conditions change.

I would say this is nothing to worry about, the removal of asbestos from modern brakes means that everything is more prone to moisture, so as eye30 has pointed out, you get "rusty" discs really quickly (ie a light orange coating across the entire disc, particularly after rain or washing the car) and in colder weather where the temps approach or drop below freezing you often get the thunk as the brakes release for the first time and then the scrape/squeak when you first apply them as the orange coating gets lifted by the pads.
All my Subarus suffered from this as did the i30, as does the ix20.

Yep, Fergie has the odd hard on from time to time, esp during this very damp weather. As said above, nothing to worry about really...

Thanks for the advice folks. Its winter in Scotland as the moment so its raining pretty much constantly. I do get a lot of of break dust across the wheels, especially if it has been sitting for a couple of days unused and the rub of the coat of rust on the disks when first applying the brakes thereafter but I get the feeling there is nothing much wrong. I don't use the handbrake when parked unless its a steep hill, instead I put the car into first. My driveway is pretty much level so there is no need. The clunk only happens from time to time, not every day, so I suspect its just the weather, but I'm going to give the hard braking before parking a try and see if that stops it.
Curiously I also read on another forum that actually applying the handbrake when parked might prevent the clunk as it prevents the gap between the disk and pad rusting. Combined with a few hard 'brakes' to clear moisture before parking and we might be on to something.
The car is going for its 3rd service next month so doubt if anything is untoward they will find it.

Sorry for bringing up this old subject
But i had the issue on mine and it turned out that it was the calipers.
They was starting to siege up and in the end i had two blue dishes which i served egg and bacon from !
This need fixing unless u wanna spend money on new front when u suddenly cant break :scared:

Doesn't do a lot for your fuel economy either. I wonder what Alan would make of that scenario. :razz:
I assume they have been fixed. What was your vehicle mileage and did the tell you what the caliper fault was. Strange it happened on both disks, sounds more like a master cylinder fault to me :exclaim:

hey
did´t happen at the same time... one failed and they replaced it.. and the reason why it failed was a broken rubber seal in the caliper allowing water into the piston corroding it till it sized up.
same thing in other side... :scared: :disapp:

Thanks for the clarification :razz:

Thanks for the clarification :razz:
worst part of it was they at first tried to make me pay for the new dishs and pads... which i did with the first caliper.. cuz they was pretty old ...
but when the second one only failed months after and burned out the dish i denided i was my fault.. and only after being in the red flag of 6000rpm talkin the the foreman he agreed and payed for the new dish and pads.... what a jerk! i want my old foreman back ... the old foreman wouldt even have blinked and just taking it on warrenty.... gah!
