I just did the brakes on my car today. I swapped the OEM fronts for Brembo slotted/drilled rotors and PBR (never heard of them, but came with the rotors for a good deal) semi metalic pads. The brakes have good bite driving around the city, but if I really get on them, I'm getting crazy brake fade... I can put the pedal to the floor and the ABS wont kick in. Any ideas?? or do the brakes still need time to break in?
