Hi All,
Hopefully a quick question... I noticed recently that my rear discs were looking on the thin side.
Before I whip the wheel off and I dig out my micrometer, does anyone know what the minimum disc thickness is on the T30?

1.6mm is mot failure

1.6mm you could slice bacon with it. Minimum thickness is 14.0mm.

14mm - Thanks! Will get measuring.

I think you are thinking of tyre tread depth there.

Or possibly amount of friction material left on brake pad?

Finally got around to whipping the wheel off. With the backplate where it is, it's a right pain to find a place to put the micrometer on. But measures 16mm, so looks like that's good. Discs seem scored though - see pic. Thinking I'll just change the pads (which are low), or with the scoring (can be felt with a fingernail) would it be better to change the discs at the same time? Don't like spending money when I don't have to, but will do where safety is concerned.

Why not buy a new kit from Milners

Could do, would prefer to fit a known brand though.
