So I recently bought a vw polo from Volkswagen in Belville. After much hassle I finally got the vehicle inspection report as the vehicles brakes shudder a lot when breaking down hill. They approved the car with 10mm of disk thickness. Is this thin or thick? I have a feeling it is quite thin. Wondering what the legal minimum is?

Brake shudder is due to warped discs or issues with loose/worn suspension bits.. as an example, I had brake shudder due to a bad lower control arm..
There probably a minimum disc thickness in terms of safety standards, but each manufacturer will have a tolerance for the minimum disc thickness allowed and this is what you need to check on.. 10mm is about the thickness of your pinky..

How long is a piece of string?
Brake disk thickness will vary from car to car, what is safe on my MkI Golf is probably not safe on my MkVII Golf.

Brake shudder is not due to disk thickness. It's most likely warped discs.

Should be engraved on the disk itself. Like below or as simple writing.

About one string length worth

Is that according to SABS string length standards?

No no too racist that standard, use AISI
Thats a balancing groove, not a thinkness indicator.Should be engraved on the disk itself. Like below or as simple writing.

You may be right
I may be crazy
But it just may be a lunatic you're looking for

usually a minimum standards, noticed that astrobrake has a list of minimum safe thickness for specific cars.
It's a 2013 polo 1.4 comfortline

Is it comfy though?
That's interesting. If that is the case vw barons then sold a car with the minimum amount of disk. My inspection report says 10mm.This is such a common Polo problem and to date I still don't know why it happens.
It should however state it on the "hub" of the disc printed.
Google says 22mm front and 10mm rear.
