yes. I guess it's "normal" then
Sorry i didn't spot that thread in the search.
yup..sound like if you stick a piece of plastic into a rotating fan or wheel..it's make that constant interval ticking sound...Kinda weird that i just started to hear it now (or does it just got worse/louder?)
any idea what it is though? I don't think it's from the rotor/pad/caliber as the pad thickness is still good and no binding.
