Sqeaky Brakes!!!!!!!!!!!

[X5M50D]

Can someone tell me what causes the brakes to squeak when you first take the car out in the morning? This has only just appeared since the winter has set in
I've done 32k miles from new and I'm hoping I don't needs new pads and discs already.
Be interested to find out.
Winter shoes going on tomorrow so will have a look at the brakes more closely when the wheels are off.
Cheers

First morning squeak that many of us experience and that goes away after you apply breaks couple times is probably due to thin corrosive layer that builds up overnight from moisture. My guess is that as rotors and pads are wearing out - it becomes easier for thin layer of rust to build up on pitted surface of pads and rotors and hence the morning sound you are hearing until pads and rotors clear that layer off. It's nothing to really worry about, but that noise aside, 32k miles might be enough for a heavy car like x5 to wear front pads (my front pads wear twice as fast for some reason). So it's worth looking at front rotors/pads.
Just my guess.

Funny.
Never had a problem until moving to Michigan from Florida.
Now first thing coming out of the garage the rears squeak.
Goes away after braking a few times when driving.
30,000 miles so will have dealer look at.

I hate this! The parking garage at work really volumizes the squeak...embarrasing!

Thanks for the response Picasso.
Hope its not going to be an expensive fix when it goes in for its service early next year.
I know its difficult to say due to driving habits but what is the average mileage you would get out of a set of pads and disks?

If it goes away after braking initially then it is likely the film as mentioned above. However, if it continues you can remove the pads and reapply caliper grease to the back plate, also to the carrier guides on the caliper itself. While not advised in a closed space you may also take a compressor and blow out the dust from the calipers while the pads are out (wear glasses and a mask). You'll be surprised at the amount of gunk that falls out.
"Bad" rotors and pads are denoted by the remaining depth, if yours still show good then try the above.

There is a Service bulletin for this you guys. This is an easy fix.

I tried to find a bulletin but my googling failed. Do you happen to know the bulletin number?

Let me find it for you 🤘🏻👍🏻🔥

Here you go

Mine are rears only.
Dealer said normal in cold weather and this is my first time with the car in MI.
Goes away right away.

Mine do the same. I love that the dealer says it's normal...if that is the case, let's go get in a brand new vehicle and replicate the "normal" squeaking sounds.

Do you know what the actual SIB number is? Perhaps I've missed it, but I see your invoice says "per SIB", but does not reference the number.

Just go to the dealer they have it. Makes a world of difference the pads need to be lubricated.

Show the pic to the service advisor if they give you trouble.

So because this is a bulletin they will perform the work for free?

I was wondering the same thing. Is it only free for people under warranty or for everyone?

[JamesInSJ]

Assuming SIB isn't going to help anyone out of warranty, the only thing I see in the service work posted above that you could do yourself without replacing rotors/pads, is pull the pads and apply a good brake paste to the back of the pads. That's standard-operating procedure for any brake job, but perhaps with years/age re-application can help. That being said, my new-to-me 2015 X5 didn't have any brake squeal the first couple months I had it when it was mostly dry weather, but with recent rain the rear brakes squeal in the morning like most here...goes away after a few brake applications.
