Well,
I m asking cause I just noticed yesterday when I had the car up, that there is a little kind of intercooler on a left side of the car, and the flow of the air is directed onto the brake disc ( left side).
I checked the right side, and it seems similar in that way, that the air from the SMIC is directed onto the right disc.
So... I assumed that Toyota just did a bit of a short cut and since they had a SMIC on the right they didnt put the little brake cooler, like the one that sits on the left hand side.
So, analogically, If its there, it must be there for a reason, otherwise there wouldnt be a little cooling thingy on the left side.
