Hi All, 

 

I've had my 2.0 petrol DSG mk3 vrs for about 6 years now, and since day one, the back brakes have always stuck on if I use the handbrake when parked for a few hours to a few days.

95% of the time I can park on the flat, so I just leave it in park with minimal pressure on whatever it is in the DSG box that stops the car rolling, but the 5% of time that the slope is too great for that, I use the handbrake. Every single time I go to pull away, the back brakes clunk to release the pads from the discs, once pulling the friction material off the pads!

The calipers move fine, and they release OK when taking off the handbrake, but the pads always stick.

I've had different discs/pads over the years, and it does it with every make, even the brembo's that are on at the moment.

Type of driving before parking doesn't effect it either, could be driving like my mum and not really used the brakes at all, so no heat in them when parking, or driving a bit spirited leaving some heat in them, they still stick either way. 

I've touched the brakes when parking, and they're not remotely warm to the touch, so pads aren't binding on, heating then up.

 

I'm at a loss as to what to do, other than chocking the car when on a slope, which is rather impractical. 

 

Any thoughts? 

Watching with interest...

 

I never once had the pads stick on my MK2 Octavia no matter the conditions or how long it stood.

 

In the same parking space, conditions, usage etc, within a day the pads will stick on my MK3 vRS. Some times it can need a decent amount of throttle before the release with quite a loud crack. After they release, it takes a few brake applications to clean the discs and get rid of the sounds. They work perfectly at this point and no other issues with the brakes or handbrake :/

I’ve got the same car as you and I’ve never experienced this. The only brake replacement I’ve had done (once since 2015) was at a Skoda main dealer with genuine parts, so perhaps try that.

I’ve never had this on any car I’ve owned!

I think I get the same thing. The brakes seem to stick on at the rear when I first pull away from being parked up for a few days or more. Releasing with a small jolt and no further problem. 

I don't even know if the handbrake on these cars use the same caliper as the rear service brake, or if its separate. Didn't they used to have a top-hat shaped drum/disc at the rear where the central bit was for the handbrake and the disk was for the service brake?

Are you sure it's the brakes and pads? I had an issue with with clunking. Replaced front shocks and rear pads. Still no joy. 
After replacing the rear bearing the clunking stopped!

Mines certainly the rear pads, I can feel it taking extra effort to set off for the first time.

 

After the initial clunk as they unstick, the car is absolutely fine for the rest of the journey or day normally

Sounds like the sliding pins need greasing

Every single car I’ve owned with discs at the rear has done this. 

Is it hill hold being over zealous. Maybe that needs adjusting if it can be.

Have this if the car's been idle for a while and I've either washed the car or it's been rained on.

I have the same problem on my 2020 mk III vrs dsg petrol. The car only has 5k miles I’ve noticed the sticking brakes and also when released the rear brakes sound as if they are grinding. Think it will be going in to garage for a check up. 

It’s cast iron particles from the discs embedded in the brake pad surface and the disc surface itself corroding in damp conditions whilst hard contact is maintained between pad and disc. Car washing, wet weather and condensation create the right conditions. Add in a bit of road salt and it’s worse.

 

I get the same and have had it on all our cars esp on the wheel most exposed to the weather. Sometimes all four wheels are bound up in winter wetness.

 

Cast iron discs corrode in water and saline. Can’t escape it.

Yes! Exactly the same. I had a petrol VRS MK2 Octavia for a few years, then a diesel MK2 Octavia for a year or so, and never had the sticking brakes issues, but as soon as I got the MK3, along came the problem. 

 

The discs and pads were changed once under warranty, but then they said it was my fault for applying the handbrake when the brakes were too hot, typical dealer answer that I strongly disagreed with to no avail! Then I replaced them myself with a very budget set a few years later to see the difference (these were the ones that delaminated!), then a brembo set early last year. 

 

The handbrake uses the same pads as the foot brake, just used a cable instead of the brake fluid, but the MK2 had a similar design, so not sure what changed. I know my Landcruiser uses a set of brake shoes with the inside of the brake disc also a brake drum, this seems to work much better, but is obviously more complicated. 

 

Sliding pins are well greased, I fully cleaned and regreased the calipers both times I changed the discs/pads, something the dealer didn't do... 

 

Hill hold I think only cuts in on upward slopes, most of my parking is facing downhill, so don't think hill hold has an impact here. 

 

This can happen on a summers day where any form of water/condensation isn't an issue. 

 

@WeeKevT555 I'd be interested in what the dealers say about this, as it doesn't seem to be an isolated thing.

Mine does this all the time although in the frozen North next to the sea so not as surprising! I thought  the same about nice sunny days but hadn't counted on passing cats and dogs marking their territory which I saw one day whilst doing some work outside, sure that'll get the corrosion going too
