It has drums in the back..
As for the orange light its on the bottom part of the dash and it looks like a car is skidding.
The light comes on when we first start it then the other day it came on while it was raining and stayed on a minute or so, it also has came on while cornering. I did not feel any difference in the way it drove but i wasnt going too fast
It will slightly break traction from a stop with no signs of the light.
