Think it's caused by my last trackday (10th aug). The vibration is not really noticeable when braking lightly. When at speed (typically > 50mph) and braking harder than normal, I can feel the brake pedal vibrate/pulse. My passenger can also feel the vibration coming from her side of the car. There's some minor vibration at the steering wheel as well, but nothing major. I read around the web on the myths of "warped" discs and the problem of actually altering the disc material due to excess heat and overcooking the pads, is it really the problem here? While on track, I did not encounter any brake fade problems, brakes felt as good towards the end of the session as the beginning. Someone suggested sending my discs to be skimmed and to install new pads, what's ASN's verdict?
