I was putting my OEM brake pads on after a day at the track and noticed that a grease seal had popped off. I'm wondering who else has experienced this?

My track day setup is:
OEM Brembo brakes
Cobalt Friction GT-Sport pads (f&r)
ATE Super Blue Fluid

I know droidekaus has posted something similar and so has another member whose post I can't find. I need to take it into the dealer to get some TLC.

 

Raceboy said that his dust boots were popping off the pistons on his Brembos in this thread here. Is that what you're talking about?

 

thanks droidekaus
