I've noticed in past few weeks, my brakes are very often over heating. I assume this is pad wear, but they look like over 10mm left both ends, any idea what the min is? The 3.2 has bigger discs than the others and braking is still good As I have a warning that they are too hot, I presume I'll get something to say they are too low? likely well before they are actually too low..... it is also just now due its 2 year brake fluid change, related? or am I just so used to the power I'm driving it too hard/fast now? .
