Should I get these?

brakes will often times let you know if something is wrong

Brakes will "let you know" if something is wrong in any car - you just need to react to it before you crash and die

I dont know of any cars that have brake monitoring systems other than a low fluid light or some sort of low pad indicator. You can mointor line pressure if you're doing data logging though. Hmmm.... where's my Mycron system...
