Warped Discs - Anyone else having same problem?

[blackpanda]

If you've managed to actually warp a cast iron disc well done.[/QUOTE]

Thanks for the links
have read similar links to this also seen much info of numerous accounts of disk skimming due to warping also.
Secret performance in Standish have recently taken the Skyline off my hands and have confirmed f/o/s disc is warped, this place is run by an ex-Nismo engineer.
My first year as an apprentice (albeit some 30 years ago) was spent turning, milling etc. with about 100 other apprentices who would often spent the dinner hours skimming discs due to warping. Back then nearly all cylinder heads were cast iron which we also refurbished, including skimming due to warping and also after porting to reduce the C.R.
I agree that most brake judder will not be due to warping, but I and many others still believe the myth busters of discs dont warp is not correct, this has been hotly debated on other forums with differing views.

Is it more than the vibration you experience during normal driving?

Yeah, thinking about it... It's only when I break relatively harshly, the steering wheel vibrates/turns side to side slightly and I have to hold it pretty tightly. I've noticed this happen with other cars I've driven which are also nearly new.

Yeah, that's the discs, if you are on warranty I would take it to SEAT.

Hmhhh okay then - Is there any way I can check and identify that this is the problem before taking it to them?

No. the warping can't been seen by naked eye... There are tools to check that, but I don't know even if the dealer has them...

Not necessarily the warping, just deposits as mentioned above?

Could it not be the ABS kicking in? Because it doesn't happen at any lower speeds no matter how hard the breaking

Only detectable with the proper tools. We are talking about really low difference, can't be seen by eye
Yes to me it was only above 100KM/H

Well, I did 800Kms this weekend, 400 + 400, and I did notice once or twice steering vibration during breaking. So I believe soon I will need my 4th pair of front disks. They were replaced the last time 9000Kms ago. :S

The car has now 130.000KMs (81.000 miles)

Maybe the OEM ones are reinforced? Because with the OEM never had vibrations...

Fit some decent brake pads

they are ferodo

do you think it's the pads?

Your Ibiza seems to have so many problems - could you sell it, save some money and buy a brand new one instead to be able to just enjoy driving and let the warranty take care of any problems that might occur?

Yes that's always on my mind, It had so many problems, most of them are solved now.

This one seems to be a really common problem, any idea what's causing it?

 

[MantaOwner]

If you go with OEM discs and pads you should be fine.

Is there a way I could save this ones? Because the vibration is still rare and low... Maybe I could adapt my way of driving to get rid of the deposits? Any advices?

I've been carefull about not applying the brake pedal when stopped on transit.

Using up 3 sets of front discs and pads in the equivalent of 81K miles is quite high usage for a light car like the Ibiza with a 1.4 85PS engine. I replaced the original pads and discs on my daughter's late 2009 Ibiza 1.4 85PS last year and its mileage at that time was 39K and I only replaced them as they were corroded on the inner side, but still 20mm thick. That corrosion would be due to the horrible winter weather we get in Scotland, plus most of the time, my daughter would be using that car on a city bypass road so lots of driving fast followed by heavy braking - she is never a light user of brakes, so with out that corrosion these discs and probably the pads would still be on that car at 41K and nearly 7 years old. SEAT do not make brake discs, neither will most of the companies that sell them, I tend to buy Pagid discs, I don't know which brand SEAT fit at factory, but these Pagid discs have never ever caused me any concerns over quality. I have only ever replaced car front discs "early" once, and that ATE Power Discs on my old VW Passat - and that due to me not using the car often enough in winter months to make sure that they did not suffer heavy corrosion - so entirely my fault!

The first (I believe they are lucas) set lasted 70k (112k kms) and they were not warped, the garage said I should replace them due to wear when replacing the pads and I did, the second (ferodo discs + ferodo pads) set warped in about 3k miles and the third set (don't know wich discs + same pads(ferodo)) are warping now after 6k miles.

 

[dm222]

would this make a difference? or make it worse?

The first (I believe they are lucas) set lasted 70k (112k kms) .. the second (ferodo discs + ferodo pads) set warped in about 3k miles and the third set (don't know wich discs + same pads(ferodo)) are warping now after 6k miles.

It's definitely not normal for discs to remain straight for less than only 6k miles repeatedly, these should last for 40-60k miles easily. Either you drive like a maniac (which is not the case as the first set lasted for 70k) or there are some other (brake) parts that need to be checked/replaced if needed on the front axle.
You can follow the guide on the link you posted, it does the brakes only good but you have a mechanical problem for sure.

I don't know if this has been mentioned already, but, if the discs are being fitted to a rusted/corroded hub without that contact face being cleaned back to shiny metal, then you could get this problem, and in general, it has been written, that most "warped" second or third etc discs have been subjected to incorrect installation.

Edit:- as you live in a hot and mainly dry country that will not suffer from ice/snow in winter - and so salt being dumped on roads, I'd hope that your front hubs are relatively free from rusting, but you never know - do you live near the sea?

 

[dm222]

No, not near the sea.
