They all have a metal braking surface. All aerospokes are black plastic painted in various different colours. I think you can choose whether the braking surface is painted or not.
If you buy a solid coloured wheel, running a brake will ruin nothing but the paint.
The paint quality is pretty bad, it will chip and flake off very quickly.
Also, all aerospokes aren't completely true (they all have a bit of wobble as they spin), but it shouldn't affect the braking.
