I have an E92 2009 335i, and I too have the squeaky brakes problem that so many threads have described here. One person said "sounds like dump truck", which is exactly right.

I know my brakes don't need to be replaced. Just got brand new stop tech slotted rotors and hawk sport pads a few months ago.

It also doesn't squeak consistently, only sometimes.

It almost always squeaks at slow speeds after a cold start... but not every time. And then after I drive a while, it goes away, even at slow speeds.

It also squeaks after I wash my car. Which leads me to wonder... is it caused by humidity? BTW, I live near Chicago, and it's very humid here, especially now in the spring.

Thoughts?...

Did you use anti-squeal when you installed the brakes?

Maybe it's rust on rotors? Like, the hub part that the brake pad doesn't touch

I think that it's a combination of the pad material and lateral runout on the rotor. When the rotors turn, it runs out just enough to brush against the pad to make the squeaking noise. I had this noise happen with the stock pads and rotor. I replaced the rear brakes and went with the Akebono ceramic pads and AC Delco rotors and I have been squeak free for 10k miles now.

Remove the pads, cover the back of the pads with a generous amount of the CRC pink goop, let it dry for half a day, reinstall the pads, enjoy silence.

Don't forget to lube the ears of pads too and clean the grooves of the caliper really well!
