Pain in the brake!
Yesterday on the way to work I noticed a metal to metal scraping sound from rear left rear at low speed without braking. On setting off back home in the evening, applying foot brake, there was a clear grinding of metal to metal. Inspection found that rear left disc was heavily scored (maybe half a mm deep) in a band about 1 cm wide. Right rear had no marks.
Limped to dealer and left it there. This morning they say the left pad was worn out and rear pads and discs need replacing for £434.96 +VAT thank you very much,
I queried why there had been no warning light and they said that there is only a wear sensor on the right hand side and that pad was ok! Another piece of wonderful design. Now I have to replace discs instead of just pads.
Question: is there any way, apart from depending on the warning lights, to tell when to replace pads? Visual?
Should I aim to replace at fixed mileage interval? Say every service? I do about 16k miles per year, D4 has now done 50k miles, 3.5 years old.2016 D4 Landmark SDV6 (Euro6), Zanzibar (late run D4)

Visual really is the only way to do it!
I'd expect them to have given you the pad thickness when they did the service, just so you have an idea of what is full, what the current wear is and what the minimum should be.
Having said that, when I had a Mitsubishi the dealer told me I had 2000 Miles left on all the pads on the vehicle. 150 miles later, the rear drivers side inner pad wore down to the backing and ruined the disc, much the same as has happened to you. When I challenged them, they said "we can't be expected to gauge the wear rate of the pad material"
So why bother telling me there was 2000 Miles left on the pads?

Cheers for that J@mes. I'd better take note of what they look like new so I can tell when they are warn.
At service last November replaced front discs & pads due to vibration under braking.
I might have to learn how to replace them mi'sel if it carries on like this.2016 D4 Landmark SDV6 (Euro6), Zanzibar (late run D4)

IMHO the price from the dealer whilst probably in line with what you might expect, is high! I recently replaced all four discs and sets of pads for around the £600 mark. The parts from TLO and the fitting by Geoff. These were the V8 Discs, carriers and pads so in your case, like for like wouldn't carry the cost of the different carriers. Not trying to ruin your day just saying that there are cheaper ways of getting the same job done with OEM parts!
Hope it's all sorted now?

I have seen this a lot on D4's both front & rear pads.
I am thinking it might be a good idea to make up a small loom to allow the wear indicators to be fitted on both LH & RH inner pads, which looking at the ones that I've had to replace the discs on, would have brought the warning up before disaster.
Mileage depends a lot on the driving style, I have some which have worn out in as little as 18,000 miles (pads)
others, do twice that!

Thanks guys.
Not got it back yet.
Yes, I guess going to a non-main-stealer would help with price - next time ...
Would anyone care to recommend a good independent near Livingston or west Edinburgh?
Do the wear indicators give you advance notice (orange ala low fuel light) or is it a go-straight-to-the-stealer-without-passing-go-or-collecting-£200 light (red ala low oil light)? If the latter then not necessary as there is a perfectly adequate audible warning - a metal to metal scraping kind of noise. 2016 D4 Landmark SDV6 (Euro6), Zanzibar (late run D4)

We have just had one of our rear ones done on dads D4 We went up to Gaydon and noticed a lot of vibration under heavy braking, got up there no problems On the way home we noticed it getting worse and worse, stopped to have a look and as soon as we got out the car we could smell burning At this point we were round the corner from the dealer (thank god ). So we went in there and explained what had happened, the lady on reception booked it in and they did it there ad then they took a look and then said that they need to replace part of the brake due to some lining comping of or something like that about an hour (maybe more) later we were back on the road with no problems And it was all under warranty Couldn't believe they did it there and then without any warning of us coming in!
Fingers crossed you get yours done without any problems

The wear indicator brings up an amber led & a brake pads worn message. This is supposed to come up when you have at least a few hundred miles+ left before wearing right out.
