The rear discs on my wife's Fabia 100bhp pdi are showing a lot of corrosion towards the outer edges. It looks as if the pads haven't really been contacting the outer 2.5cms of the disk. I think this is probably because there is very rarely weight in the back of the car so the back brakes don't do much work.

I've looked at the pads and the outer edges show no wear at all; I assume that the pads are of very hard material so I'm wondering about replacing them with softer pads.

The front brake discs also are showing corrosion for the outer 1cm. The car has done 6,000 miles.

I'd be very grateful for comments.

Had/ got this on my 2001 tdi. Fronts failed mot with only 21,000 miles.

Rears are on way out as well. :thumbdwn:.

Bit miffed after such a small mileage.

Not had any problems with mine . They do have some corrosion but it is very small near the edge and it recently passed the MOT no problems.

My car suffers this also. The rear discs were both showing bad rusting at the outer extremes of the disc. It does not shift upon heavy use of the brakes like the rust you see after the car has been stood for a long period.

Since changing the standard steel wheels for a set of Alloy wheels, the corrosion has gradually reduced. My car has done over 60K miles. I am not sure if either the discs or pads have ever been changed. All my servicing for the 45K miles was done under the Skoda 3yr / 45k miles free servicing offer.

The price of a pair of new discs is a big dis-incentive to replacing but if the MOT fails on this it is a case of do it.

Do any of the owners of the affected cars have alloys? I am guessing so if you can easily see the discs.

Yes, standard 14" alloys.

Quite common on the Fabia and also some Octavia's.

Usually down to lack of use, either low mileage cars or ones that are very rarely loaded.

Lots of short trips. 4 miles to work and back. :thumbdwn:

I'm not suffering the problem touch wood, but I have done 23k before the MOT.

Not the lowest milage I know somebody who did 54 miles in a year!

Just to add to my original posting. I've now found out that one of the causes of corrosion on the rear disks has been chamfering of the outer and inner edges of the pads. This was done by the dealer last September in an attempt to cure the usual groaning noises from the brakes when reversing. It seems that so much material was taken off the pad edges that only the centre parts of the pads were contacting the disks. It would have taken thousands of miles for the pads to wear down enough for the whole pad to contact the disk, by then the disks would have been completely ruined.

I've now replaced the pads myself as I can't be bothered with the hassle of arguing with the dealer.
