You nub-ette, that’s the normal yellowing of the rotors when washing your car… I’m assuming now that you’ve never washed the car yourself? SLAP
Kidding, take a look at your rotors after washing your car, you’ll see what I mean. That’s just some crap/rust that’s on the very surface, and comes right off after a few nice drawn out presses of the brakes… they are the reason your brakes squeal after the first few touches of the brakes. :R
The 20g’s for the SACHS suspension is nothing to laugh at either… 
Nor are the few handsome g’s spent on that ‘minimal-looking’ audio-setup!
