    Just had my 2012 C250CDI serviced. No surprises, except front brakes. The car has done 30,000 miles, and the front disks/pads looked OK for another 5 to 10 thousand miles.

    However the dealer says the disk is down to the minimum (26mm), but the pads are OK, 5mm+

    £423.64 to fix!

    Are W204 disks prone to wear fasted than pads? seems a little unusual.

    Anyway, I'll replace the disks/pads myself, it looks fairly straightforward.

    Exactly the same situation as mine, discs are well down but loads left on the pads. Very easy to do, I think you can get the bits for about £120.

    I'd get a second opinion.

    They said the exact same to me with similar price at my service, sent via video. Obviously I declined

    You could just wait until the pad warning light comes on.

    Isn't that dangerous? Wouldn't it take the discs below minimum if the pads still have 5+mm on them?

    Funnily enough that's what the stealer said to me many years ago, and then I found Olly and PCS who ordered up all the parts to find the discs were no way near the the minimum, in fact 2 to 3 mm more meat on them.

    Never been back to a stealer since.

    Get a second opinion :D

    A set of pads should last a set of discs. I'd measure them again to be sure

    I'm amazed that they said 5+ mm of pad left is OK* but I wouldn't be surprised if the dealer is quoting MBs 'service limit' which is different to the actual min disc thickness, probably 25.4mm if they're 28mm new and MB say 26mm is the min? My s124 for example... 294 x 25mm front discs, the MB service limit is 23mm while the actual min thickness is 22.4mm. Below this they obviously become more prone to cracking and fade (less material = less of a heat sink) but it's not like they'll instantly fall apart... not recommended but there'll be another several mm at least before this happens

    * Obviously it is but stealers often to want to replace pads with even more life than that left in 'em to [cough] lessen the chances of you being 'inconvenienced' between services [/cough]

    As olly said, run them until the light comes on.

    And yes w204 disks wear very quickly.

    My front discs looks heavily worn to me (by eye) but when I had it serviced recently the independent specialist I use said they are good for another 20k miles!

    I did enquire about having them changed and was quoted £250 I think.

    I'm still on original pads and discs at 48k, and nothing reported at last service and MOT in September. Maybe they didn't check them! but they look ok to me.

    Those parts sound good value. I changed the discs and pads on my Porsche 944 four years ago and the cheapest I could get the parts was about £350.

    Mine is still on its originals too at 40k, they were reported as needing replaced 2 services ago, because of corrosion. I bought new ones myself from MB but still haven't changed them. At this years service, they said they were 60% worn, they were obviously at it last year.
