New brakes vibrate when hot
I am having some weird issues with the new brakes that I've recently installed.
I've installed brand new OEM Zimmerman rotors on the front, PFC 08 pads and I did a brake fluid flush for good measure.
I followed the correct bed-in procedures. This is not the first time I am changing the brakes on the car, so I am highly confident that I know what I am doing.
During normal street driving the brakes are fine. Very grabby, very predictable and the performance is very very good.
Unfortunately, on the track, when they heat up a lot, they start vibrating. It's really weird and unnerving. As soon as they cool of, everything is fine. The HDPE instructor that rode with me told me that the pads are overheating, but I don't think so. They are rated to almost 2000F which at which temperature the rotors will be glowing yellow.
Any ideas what's going on here?
