I have a 2004 530i sport, 6 speed, which has been a great car. 43K miles.

Recently there has developed a high pitched squeal noise when I apply the brakes. It doesn't happen all the time.

New brakes in March 2008.
No rough driving.
It began in the recent cold weather. Brakes work very well.

Have had it looked at by the dealer once. Was told it was just due to the cold and there was nothing to do. However, sometimes in the cold weather it happens, other times not. No specific time of day.

Any suggestions?

Danke!!

Yeah I got the same thing, I'm intrested as well.

That's correct.


Nothing you could do.

I hear it from almost every E60 these days.

Yeah this is very frustrating. My rear brakes squeak alllll the time. I have taken it in 4 times to have the pads replaced but everytime they say the pads are fine, "we just cleaned them up"....

My rear brake sensor goes from 30,000 miles until service to 1,000 miles until service in about 1 month.

From my understanding, the brake dust causes the brakes to make noise. I have found that if you go to one of those self car wash places with the high powered hose and spray in between the caliper and rotor, this helps somewhat.

Either that or buy some axxis brakes

Search around on the forum, a lot of people have them, no brake dust!!

my car squeals too. its kind of embarrassing driving through parking lots when people are outside. People prob think i am an idiot like i can afford a 5 series but not new brake pads

Same thing, squeaking sound. i though its sensors but its not. my brake pads are still good. Seems like it's common.

Also, my calibers look rusty - i wonder is there a way to clean them? or paint?

Its the brake sensor, I had the same problem with mines with about 80% left on my rear brake pads. So I changed the brake sensor and the noise went away for about 3 months and came back. Its just how it is, when the sensor is brand new, there is plastic covering up the magnet or metal part of the sensor but eventually when it wears down the metal gets exposed and when you brake the metal rubs on the rotors which makes that annoying squealing sound. Bmw has created a new sensor which replaces the old ones which supposedly made out of better material and eliminates the squealing but I still get it. You can try changing the sensor out and see what happens, I think its like $25 at the dealer. Oh and one more thing, make sure the brake pad material has a decent amount of lining left or else the new sensor will be too thick to fit in. Hope this helps

Mine had the same problem not too long ago and the pads were fine. I took it to the dealer and it turned out to be one of the sensors on the rear passenger side that had to be "grinded" from what they told me. I let them handle it since it was under warranty and Ive had no problem since.

I HAD THE SAME PROBLEM AN I TOOK IT BACK TO THE DEALER THEY SAID YOUR BRAKE PADS WERE UNEVENLY PLACED AND THE "BEDDING" WAS WRONG SO IT WAS RUBBING THE WRONG WAY.. I REMEMBER BECAUSE THE SQEUAKING WAS SO LOUD IT SOUNDED LIKE I HAD NO BRAKE PADS =P SORRY FOR THE CAPS =_
