Front Disc minimum thickness

[PhilL]

Can anyone tell me the minimum thickness for the front discs on a 54 reg E270 CDI Estate?

They are smooth but with a lip around the outside. I have measured them at 0.951" (24.1mm). I would like to hold off for a few months but have an MOT in a couple of weeks and would not want it to fail.

Of course, I wouldn't want it to be unsafe either!

It won't fail the MOT on disc minimum thickness afaik -only if it degrades brake efficiency to a level it fails the rolling brake test.

There is a wear indicator on the edge of the disc. It's in the form of an elongated indent.

Some discs have min thickness stamped/embossed on them.

There should be no more than a three mm lip around the edge, though as said, not mot fail.
