Brake Discs Below Minimum Thickness?

[Mercedes2018]

I took my Mercedes for a service today and I was told my front and rear brake discs are below minimum thickness. The minimum thickness for my front brake discs are 26mm and they are currently 25mm so 1mm under minimum thickness. And the rear brake discs are 7.3mm minimum thickness and currently they are 6.5mm so 0.8mm under minimum thickness.

The brake pads aren’t fully worn yet and have still got life left in them.

Questions:
1) Is it worth replacing all brake pads and discs now or shall I wait until the pads are worn down?

2) Also is it dangerous driving with the current brake discs being below minimum thickness or is this normal until pads are worn?

Thanks

I'd say they are having you on....main dealer no doubt?!

What thickness is a new disc? - around 28mm most likely.

Are the discs lipped? scored? do you experience any brake judder? - I'm going to take a wild guess and say it's a no to all of the aforementioned.

I bet if you took it to a local independent/family garage they'd take a look and say they aren't even half worn!

It also depends on how many miles a year the car will be doing - if you are doing >10k they are going to last a good few years longer than if you do 30k+ a year!

Cheers,

OP

General question how many miles have these discs done? Are they on their second set of pads?
