:werd: the last thing you want on your car is bad brakes...

as far as your radiator question, its perfectly normal for the radiator to stay on after you shut down upward to 15-10 minutes...I have no clue why your radiator stays on close to 30 minutes, that jus weird. Does it stay on for 30 minutes EVERY time? I got a feeling you've been testin out your new H22, exploring the wonders of the H-series VTEC (you're running the shit outta it)...so if thats the case, ease up on the engine; dont get on it a lot the next time u drive and see how long the radiator stays on then.
