Hi,

#Skoda Fabia mk 3

I had to have  the brake discs replaced Just over a year after I bought he car from new. I had to replace them again about 15 months ago.

Now I am having to replace the rear disks again because the back right disk is showing the same fault heck out the attached photos.

Has anyone else experience this disc disintegration problem?
 

Thanks

Yes. It's called "corrosion", and is very common in rarely used and/or gently driven cars.

Called pad bite I believe by some, and is the pad stopping a bit of the disc from exposure to salty water (or holding damp close?), salt can be from the seaside air or more likely winter salting. Panels and stuff are fairly well protected but disks are just sat out there in it - though a wet car in a damp garage is in an even worse place!

In my experience its because recent Skoda's are fitted with the cheapest low quality nil carbon content rear solid disks that they can find along with a high iron content pad that is slightly porous and loves to share its soggy contents with the soft cast iron disc when parked up . Great for dealers, lots of regular £299 disk/pad changes, almost an annual service item.

Solution is simple. Ditch the dealer and go somewhere that will fit a good quality disc and pad. Ideally, supply your own,  if you can find a high carbon content disk and ceramic pads. But just about any aftermaket make is better than the rubbish Skoda/TPS "fourplus" disks/pads.

 

Nil carbon content steel, I knew they were simply clever but that is really clever considering that higher carbon contet steels have increased corrosion.

 

There is no question though that any aftermarket discs, even the cheapest of the cheap that I fit massively outperform the factory fitted ones in terms of corrosion resistance, it cant be because of added cheapness or all the Chinese pattern part manufacturers would be producing the same.

 

Jr is correct, I am indeed wrong in thinking high carbon means greater corrosion resistance, perhaps I should have mentioned chromium instead.

However, we can all agree Skoda brake discs and pads are pants, avoid.

Amen to that!

Thanks all. A very interesting discussion.

I always thought Skoda pads are made of Brillopads and discs of tin foil according to my Roomster. After only 2000k miles the wear lip was appearing on my front discs and the rubbing noise when the brakes are applied is disconcerting. Nevertheless 8 years later and 43k I have 4mm left on the front pads and goodness knows how much on the rears as they were fag paper thin when new. The rears have little work to do and the discs are not so polished as the fronts. This autumn will be decision time where to get my first replacements.

2,000,000 miles isn't too bad....

Are you sure? Even if you mean 2_000 miles and not "two million and forty eight thousand miles" as typed, that rim is probably corrosion on the unswept edge of the disc rather than wear.

Typo 2k, Oh I have been ribbed.

Rapid spaceback; 28K miles; same issue and replaced with anything but the OEM discs/pads.

Fabia III original rear pads and disks at 50 000 miles,  5 years old and are about half worn. 

 

 

You need to clean them yearly to make them last.
