Hi everybody.  I have a 2021 octavia diesel automatic first edition just coming up for 1 year old / 9500 miles.  It wasn’t used for about 3 weeks recently as I was ill with covid.  Went for a drive yesterday and the whole car is juddering when braking at higher speeds.

 

is this likely to be worn brake pads and something that will come under warranty?  The earliest I can get booked I’m for my free dealer service is mid March.

 

I’m tempted to just go to my local trusty and far more convenient mechanic.

 

Thanks for any advice.

Should not be brake pads at 9500miles! Does it happen every time? Only above a certain speed? If its been left for a long time, it could be debris/rust got stuck in the pads but that should clear and be fine afterwards.. If its severe, it could be a warped disk, but they would have to have got really hot for that to happen! 

Does it have EPB, electric parking brake?

 

These clamp the rear discs very hard when applied. In damp winter conditions, along with what I suspect is a pad composition containing copper, the disc corrodes under the pad while its stood and applied. You can usually see the imprint of a pad on the disc and if stood a while this is quite marked corrosion. This also leads to the impression of juddering under braking.

 

Note the corrosion is usually much worse on the inside and unseen face of the disc, on the side where the piston is.

 

A few sessions of heavy braking from spwed can usually clean the disc if the corrosion isn't too deep. A more effective method is to apply the electric handbrake while travelling at speed though this is dramatic, brown pants moment type thing. Definitely not for the light hearted. Should only be done in controlled conditions on deserted straight roads in good road conditions. Tyres need to be warmed up otherwise they will lock and ABS will be going like the clappers.

 

Try the heavy braking before asking Skoda to look as they will simply say wear and tear and ask for £300 to exchange discs and pads.

 

Warranty on brakes expires at 6 months/6500 miles, clearly stated in the small print.

 

If you have a sympathetic dealer, they may give you some goodwill, but this is a rare occurrence.

 

Hi, have taken it back to the dealer and they confirmed both front discs are warped.   They are out of warranty because I’ve done 9000 miles but I have argued there must have been a fault for both of them to warp as I am a slow driver. The car is unsafe to drive at the moment so waiting till next week to find out.

This forum is the only one I use where warping discs are a common occurrence. On another forum I use, I could count on one hand the number of times it’s been reported in the 15 years I’ve been using it. Personally, I’m not buying it. 
 

But, I can’t see them so 🤷🏻‍♂️

I bought a Škoda approved Octavia 4 tech 1.5 tsi with 10k on the clock. I took it back after a few days due to brake judder. It needed  front discs, pads and wheel bearings. This was a car that had been serviced prior to collection the dealer said that they don’t road test used vehicles! The good news is the dealer replaced everything free of charge and also updated the software but I am still getting the sos problem. The car makes a popping sound then dials sos!

Warped discs after 9000 miles - maybe if you had been yeeting it around a racetrack repeatedly - in normal driving thats a manufacturing fault. If they give you issues regarding it, just book a DEKRA engineer inspection (around £150) and that'll soon put a rocket up the dealers backside.

Do I get them to book a dekra engineer or do I need to take my car away and do it myself?

You book it yourself and they perform an inspection on the car wherever it is currently situated.

Mine warped about 6-7k mls. Notice you have the DSG too. I'm thinking they fitted disks that weren't quite up to the job especially as you have less control over engine braking with DSG unless you use manual mode. Done double that distance now on the aftermarket ones I got fitted and no sign of warping at all.

VAG OEM discs aren't the best.  The front ones on my wife's 2019 Karoq 190 TDI were cooked and warped at 18k miles.   I replaced them with drilled Brembo discs and Brembo HP pads. 

Update:  we were given a courtesy car last Monday and my wife contacted Skoda U.K. customer service.  Today we have found out that Skoda are covering the full cost of replacement.  
 

My wife is a badass money saving expert lol.

Both my brother and I have a Mk 4 Skoda Octavia and had vibration during braking.

My brothers car had new front brake disks and pads fitted a few months ago and I had to get the same for mine this week.

Both our cars are under 25,000 miles and we don't drive like boy racers.

I actually think my new brakes are better than the Original ones, just wish I didn't have to buy them myself, especially on a 20 month old car.

One thing you can do is to tell dealer it will be inspected and they should place the used discs in boot or footwell, so they can be tested.   Also tell them if Independent inspector finds their diagnosis wrong they will be charged the inspection fee.   
 

They will the try much harder to find the manufacturing fault which is clearly there unless you have bee taking it around a racetrack.

 

 

Contrary to popular belief I reliably informed you can't actually warp car disks (well not that easy). The most likely cause is lateral runout on the disk. If you google you will find out more. Basically it's pad material sticking to the surface of the disk over time and it gets to the point where it's that bad you feel it through the pedal (if fronts are bad) or through your bum (if its the rears).

 

Lateral runout starts to occur between 500miles and 5000miles depends on the severity of the issue. I've had this problem when new disks/pads were fitted incorrectly. If the disks to hubs that have runout above a threshold or  debris/rust exist between the hub and the disk rotor... even the slightest crum, this is enough to lead to lateral runout developing.

 

It's probably not helped if the car has been left laid for a while and rust has had time to corrode the disk beyond repair, making it uneven and they braking will be all over the place.

 

Hope this helps.
