Hard tracked brembo's will change color... it's pretty common.
Looks to be the same basic brakes as the front of my car... I bought some EBC yellow's (track temp brake pad) for I think like $160. I guess that could be considered expensive.
The rotors are killer.. at least the subie ones are. I was looking at some nice aftermarket 2 piece and those are like 600 a pair.
If you have the STi Brembo's, then they are very similar in design. The Subaru calipers are slightly larger hydraulically 40-46mm and the Volvo calipers are 40-44mm if I remember correctly. I have the prints for both at my desk, I will verify later.
