i have a 98' gsr, and every time i press on the brakes sometimes hard sometimes not it feels like somethings grinding. i took it to a brake shop and they said my pads were fine and my rotors were good but they could be changed in a little while. It sounds sorta like somethin with abs and my abs light came on so im guessing its that. But if its happend to you let me know whats the problem, thanks
