I have a 2014 Elegance 75bhp,  part of spec includes regenerative brakes. When applying brakes slight vibration felt through floor pan. Car covered 25000, plenty of meat on pads, car also has alloys. Unsure if this is a characteristic of the three cylinder engine when slowing down. Has anyone else experienced a similar sensation? Or perhaps a braking issue? 

 

Thanks, Mark

Brake discs tend to warp with original brake pads. I'm not sure why, but maybe they generate too much heat. I have had 2 pair of warped discs and then I put another brand pads. Haven't have that problem since. 

The only vibration I felt was the other day when I braked on the road to my home which was icy and the ABS kicked in. Quite reassuring really .  The only probs I've had has been the occasional squeak from the discs which disappears after a couple of brakings and the dreaded sticking of the handbrake after parking, but even that doesn't happen anymore. Okay mines a Mii 74ps but same build.

It’ll be because the discs are grooved (not smooth) so the new pads have to re-groove (broken in..) into the disc. 

 

Also if you sit at traffic lights with your foot on the brake, it’ll create a heat spot on the disc which then unevenly wears - causing them to warp.

I find it hard to believe that "hot spot" theory. I haven't have that problem in other car than Citigo. And I have owned quite many cars. And I don't have the problem with Citigo now when I have EBC Ultimax pads.

It’s because when your braking to a stop your creating heat so if you don’t lift of the brake when your stationary the heat is trapped between the disc and pad creating the hot spot. Obviously it isn’t going to cause problems straight away but it will after a while.   

Anyone can believe the theory or not as it does or can not just happen in theory but it can in practice with spirited / sporting driving in some cars, as many know over the years and with red or white hot brakes are not going to apply the brakes, and even in 2017 /18 might not want Auto Hold / Electric Handbrakes on when stopping with roasted / toasted brakes.

 

As to the Citigo, then crap discs / crap pads more often the issue, 

hence the Threads & posts in this section where 'Brake Discs' have been replaced under warranty, even when some dealership employee said 'No way Jose'.

Skoda UK & Skoda CZ (VW / SKODA / SEAT Bratislva know the story. Suppliers of components / lack of Quality Control,  suck it up and replace.

But then why Citigo is the only car in the world which does that? Must be Internet rumor some kind of.

Citigo's discs and pads are not crap. They just don't work in the Citigo. Those pads gives a lot of braking power which is needed as we have "City Safe Drive"-system. Also ESP works well when pads gives a lot of braking power.

 

Brake pads includes a lot of metal particles. That's most likely the reason why they create so much heat.

Really, heat generated in city driving in a Citigo and braking forces generated stopping an Up!MiiCitigo ?

 

Maybe on a Citigo with more go go, and those brake jammers, but generally that is in another universe.

Maybe the sintered pads are just not the good match on some and rather inappropriate discs  

then.

Yes, really. I'm not a boy racer but my discs was blue when they were replaced. But this might to too hard to understand on your side of the screen. Change your own pads and discover what wrong with them. I've changed brakes for both of our cars and I'm happy now. No more warped discs. One have original discs with EBC Ultimax, 35tkm. Another have non orignal discs with EBC Greenstuff, 35tkm. I cannot recommend Greenstuff as it doesn't give as much braking power as I wish. Ultimax works better. Ultimax doesn't give as much braking power as original pads though. You just have to push harder on brake pedal.

I am a Grandpa racer, Karts, Mini's, Imps, Strada's, Iq's, Picanto's, Fabias and even a wee blast in an Up!MiiCitigo ASG on an occasion so i understand perfectly.

The Citigo discs and pads are just fine. There are things you can do to warp the discs and these are normally:

 

Overheat them (use beyond design limits or partially seized / sticking caliper / riding the pedal)

Mount them on less than perfectly clean hubs (contamination on the hubs will cause the hat to not be flat and will produce runout over time)

Mount them on poor quality hubs (not flat or not rigid enough)

 

You can also produce vibration by sticking contamination to the discs. This can happen if you get the discs really hot and sit with the brakes on.

 

Discs can go blue as a result of heat, or as a result of surface rust being removed in cars that are driven infrequently.

 

In the Citigo's case, the hubs are, in my experience, the culprit. The only way I've managed to keep a set flat was to scrupulously cleaned up the hub faces and torqued them very progressively and accurately. They stayed flat for nearly 30,000 miles. Problems only started to show after dealer took the wheels off as part of a service. 

There being a problem right off, those with a car delivered off a transporter from the factory, no wheels off at a PDI and still people have issues.

It is not like Skoda has not well over a century of experience building cars, Motorsport Heritage and success and yet turn out small capacity engine light vehicles and customers need to be prepared for them being like cars from decades ago. Or the VW Group that spec them and build them.

Not 'simply clever', just Design, Manufacturing, Material and Quality Control failings, hence you get  new discs under warranty claims.

Edited 1 January, 20188 yr by AwaoffSki

It's quite possible that the initial assembly is less than perfect, but if the hubs where any good, it shouldn't matter.

Here we are in 2018 and millions of City cars on the UK roads, even European Built South Korean with 7 year warranties have brakes fit for purpose now.

Even the company that was a joke in all of Europe  'Dacia' can have Renault brakes and not expect the kind of issue that the biggest or 2nd biggest car manufacturer in the world 

has because of penny / euro pinching. Lack of consideration.

The Up! GTI will likely have no such issues, or time will tell.

Less than 5000km from new and I already had warped discs. It wasn't bad but I knew it wouldn't get any better. I replaced discs and pads. For our third Citigo I bought pads and changed them soon after we received the car.

 

*********

 

A lot of metal particles in OEM pads. Good braking power and probably good longevity. But too much heat is generated in front, as there is drum brakes at rear. And usually not a lot weight on rear axle, so electronic brake distribution cannot brake with rear brakes as much as heavier cars. 

It really is highly unlikely to be heat. I've run very ordinary discs to huge temperatures on a regular basis and not had warping. On the other hand, if you look at the drive flange, it's very weedy. My first Citigo had signs of run out from very early on in its life, the discs had certainly never seen big temperatures.

Some are just too accepting of VW Group procuring and fitting cheap sh!te. 

 If not fit for purpose make them pay to replace then they will eventually learn but then still they get away with the European Home Market being their cash cow.

It is not just brakes, it is the same with gearboxes.

Nothing wrong with the gearboxes neither. You probably should go and buy more Suzukis.

It's true! Even in city driving you can cause your discs to warp by...braking late a few times and/or for example going downhill at 30mph braking late and creating a lot of heat and if like many drivers you then keep your foot on the brake whilst stationary, the heat from the very hot brake pads will start to warp the disc. Once warped even a little, this exacerbates the problem and causes that spot to heat up everytime you brake making the problem even worse as the disc just carries on warping. In general, it's not a car problem but a driver issue. The only cure is to replace the discs or have the warped discs skimmed. But better to replace in my opinion. Most cars have ventilated front brake discs to help alleviate this problem. They help to dissipate the heat away from the disc to atmosphere helping to reduce the chances of a warped disc. But even ventilated discs become warped if driven badly ie: foot on the brake all the time after a stop especially if you have braked heavily or even gently over a long stop. Brakes generate a lot of heat!

Strange that in over 2 million miles of driving, I've only ever had it happen in the Skoda Citigo?

Not strange, VW Group specced brakes just good enough and then the quality and fitment is so so, 

and out of not that many Up!MiiCitigo produced there seems to be a bit of an issue regardless of how experienced drivers are and not just with Novice / New drivers.   Leads to the question, are the Brake discs really fit for purpose even on a light not high powered vehicle in normal use?

 

ChrisGB, are you a truck or taxi driver?

2,000,000 divided by 40 is 50,000 miles a year.  Lots of driving.

I didn't change my driving style but brake pads. Problem solved. And I still don't believe hot spot theory. 

Donald Trump does not believe Global Warming is an issue, and he is a self confessed genius.

Maybe you are right with the Citigo, but 'Hot Spot' is not just a theory on other vehicles.

I drive very heavy vehicles and no warped brake discs due "hot spot". That's just ridiculous theory. Something very badly wrong if discs get warped after braking. 

 

Hard braking just before pond would ruin brake discs because of temperature changes. That was a problem with Ford Sierra back in the 80's.

 

Edit: Kind of funny that a person who doesn't even own a Citigo "knows" that brakes are crap.
