How do you know when your disc is bad for your breaks? (Yeah I know, when it quits breaking) but I still have the stock setup and have been doing some winter upgrades and came across it and was just curious. The last time I drove it the breaks seemed to work just as good as when I got it (I honestly dont use breaks that often, as weird as it sounds). Granted I dont want to spend any dough I dont HAVE to, but will if necassary. Anyway heres some pics, you be the judge. (Sorry for the pic quality)
