What does the (!) dash light mean?

I used silicone fluid back in the 70's when I used to rebuild cars and didn't want the nicely sandblasted and repainted callipers to suffer paint damage. I did not consider the seals as I thought that silicone fluid would be fairly inert. I also used cunifer bake pipes which are copper based and don't corrode.

I don't know about the fluids, but I was a big fan of copper brake piping when I was doing car jobs in the old days. Flaring tool and a box of various ends, I was very happy to re-pipe a whole car in one go.
