This was interesting. After my later sessions at Thunderhill yesterday I heard this ticking sound. I realized it was from the front rotors. The rear rotors were also making a noise and it was more like a hissing sound. I don't think anything is wrong but wanted to share so nobody is surprised by this. Has anyone else heard the ticking sound?
