Pads and discs at 25k miles

[Richyboy]

Smart Fortwo service at merc dealer (wasn’t sure where to post as no heading for smart). Dealers says I need new pads and discs at 25k miles, is that normal? Use of car 90% dual carriageway and motorway. Never had discs wear out so fast on a non track used car.

Pads maybe but discs should last longer than that. Don't they usually say 2 sets of pads to one set of discs.

Pads on my E class with mostly motorway driving would do about 50k miles and the discs were changed every 100k miles.

I only had to change the original rear discs last year after 306k miles.

Dealers will usually say discs and pads need changing together and most of the time this is untrue. Regardless, you'll get the job done cheaper at an independent so I'd try and get a few quotes first, if possible.

On a lot of modern cars the amount of margin from new to minimum thickness on discs is very low, I've just done 30K on my E Coupe, front discs needed replacing with the front and rear pads as they were only .5mm above minimum, (so that's .25mm per face of the disc) they would have been way under by the time the new pads had worn out. (this was me measuring everything and replacing it, not a dealer telling me), have a look at one of the spares sites and see if they list the new disc thickness and ask for the current readings if you are unsure if they need doing
