I've been having problems with very very loud noises (basically kinda like a ship's horn), when reversing. Forward, there's a quiet squeak when braking now and again (mostly when the brakes are cold). I am sure it has to do with the brakes as stepping on the pedal modulates the noise. Been told it's very probably worn sliders on the carriers, however can't find those anywhere from a breakers... Tried 24/7 spares online -- they've got them only for the solid disks (mine are vented as it's a V5), tried Sports Car Breakers near the airport (Edinburgh for those that are familiar with the area), they don't have any. A new carrier with sliders costs 90 quid (got a used offer for 70 from 24/7 spares at the end). Any ideas what to do? Or could it be a seized caliper?
Awful noise when reversing

You can buy repair kits and bits from biggred.co.uk. I'd think it's most likely the rears.

It's definitely the rears. One caliper was seized and was changed when I bought the car. However, the noise came afterwards. I'm booked for the MOT and if it fails on account of that, I'll pursue it immediately, otherwise I'll get the guys to have a look and see what exactly needs changing...
Thanks for the website!

You say you need new sliders but have you tried simply popping yours out, cleaning them up and re-greasing them?
Did this with mine at the weekend was a very easy job.
Another thing to check is that the handbrake levers on the backs of the callipers are fully returning, ease them up with some wd40 and put a light amount of grease there too as this was more of a problem than the sliders on mine, I have also eased off the handbrake cable adjustment slightly so the cables go nice and slack when the handbrake is off.
Hope this helps.

Unfortunately, I rarely do any of this under the car work myself as I am devout of a garage and a proper toolkit (mostly no proper lift/jack or stands).
Now to give you a bit of history. I bought the car with no such sound/problem. The front pads needed changing, the rear disks were pitted, so went for a full on disks and pads change at a local VAG specialist. One rear caliper was found to be ceased, so was changed as well. After that, got a noise when braking forwards, car went back and calipers were re-greased -- noise went away. Shortly after that, a noise when reversing (without braking) started to develop. Car went back again, sliders were cleaned and re-greased, helped for a while, but noise returned. At one point it got so loud it would quite literally hurt your ears, make you think the car was about to fall apart. I was unwilling to change the remaining rear caliper as upon the previous inspection it was alright. At this state the car went in for an MOT and passed. Quite an imbalance in the left/right side of brakes (interestingly enough on both front and back), which on the front at least I attribute to having a driver on the right side, hence giving better traction and braking. Anyway, will post the printout here once I am back home and can take a picture of it. So as I was getting rather unhappy with that noise, I went in search of a new carrier with sliders as the guys at the garage suggested, could not find one for decent money, so found some slider bolts and rubber covers, and changed those. Has been much quieter since then. HOWEVER, now there is an intermittent noise when braking forwards, and there is an occasional really loud noise when reversing. Pushing the car along with the engine off results in a grinding sound from both sides, however, with the engine on and a prod on the brake pedal, the noise disappears from the side of the new caliper and remains on the other side.
This is the full story
. Hope someone has the patience to read it all.

Not sure if this helps..
But I've started a thread on the briskoda forum about the same thing happening on my octavia vrs
http://briskoda.net/forums/topic/183084-brakes-groaning/
Turns out there's a weight you can put in to dampen it down. Something about resonance on the back axle. It's a big thing on the skodas called the octavia moo!
The vRS has vented rear discs too, so I bet they're the same as the V5's.

Right, I know this is a bit old, but I only got around to changing the other rear caliper on the car the other week.
The reversing sound is gone now (very happy about that), but low speed low pedal pressure braking causes a screech to be made. It's not crazy loud but it's quite audible. Has that anything to do with the octavia moo, or is it something else? Any ideas, as it's driving me crazy, and I do not really want to throw any more money at it. 2 calipers and 1 set of sliders are just enough for me at about a combined cost of about 250 quid including labor.
