OK, I know they're considered sacrificial now, but I thought it was still expected that you'd get through a couple of sets of pads before the discs needed to be changed?

On daughter's Colt, the dealer has reported that the discs are worn (and they do have a noticeable lip) but the pads are fine. Quizzed the service manager and he assumed the pads had been changed - they haven't.

Just how hard are pads these days - is this becoming normal?

What is the mileage?

The lip can be skimmed off or if your rough like me a angle grinder carefully can take it off.

If they have done 60k+ replace them for new.

It's normal for brake discs to develop a lip on the periphery, but it may well only be largely corrosion on the part of the disc which doesn't touch the pad. Did the dealer say that the discs categorically required changing or was he merely commenting that they were worn? How much were the discs worn, or more to the point how thick were the discs compared with the recommended minimum?

The car has done 39K miles, 5yrs old, gentle semi-rural use.

The dealer said they were worn to the manufacturers limit and advised (but didn't insist) on them being changed. I know there's not a lot of difference in the new and worn figures, so I can well believe this is correct. I just would have expected the pads to go first.

Interestingly there not even a comment on the MOT which they did at the same time. He said they don't measure for the MOT but I'm surprised they didn't even note it as an advisory.

Changed the rear pads on my Vectra at something like 40,000 miles. Discs needed changing as well.

Changed the front pads at 60,000 miles. Again, the discs needed changing too.

Seems the norm these days for the discs to last only as long as the pads because they're equally as hard (or soft?)

Right - that's what I'd expect, absolute worst case (ideally 2 sets of pads per disc, as someone else mentioned).

But in the case the discs have apparently worn out before the pads!

If you don't get them done, it wont be the end of the world, as the MOT proves,

But if you've (or your daughter) got the wonga, then get them done.

It's common now with no asbestos in the pads-my Fords,on average,get thro' one disc for every two pads.Just as quick to change.

My dad had an Almera 2.2 TD (2001). The pads and disks were lucky to last 20k

The problem with brakes is everyone drives differently, my dads car last 22k on a set of pads due to him using the brake too much on hills etc, mine did 36k and were 35% worn.

Your daughter may drive the brakes hard or you just have been unlucky, id grind the lip off and fit a set of pads, if you don't take the lip off it will squeel like a pig!!

Followed an E220 this morning driven by the former method: accelerator as switch and a corrective dab of the brakes every ten seconds, even uphill. Never seemed to drop more than a length and a half behind the Golf in front.

I put it down to ineptitude until it went for the left-turn lane at a roundabout, ran round the outside of four cars and dived into the straight-on exit - so it was presumably a combination of ineptitude and diarrhoea - and a leasing company to pay for the brake pads.
