squeaky brakes

What are you guys doing for the freaking sqeaky break noise. Pads not nearly worn. I've pressure washed it out and everything. Still not getting nothing. I've got some crap from auto zon but it only works for a few hours then it's right back to it's old self. Tired of giving the dealer 125 to fix it every six months. Probably the only thing I hate about my car.

try bedding them in. Go to a road, and drive up to 40-60 mph. then slam the brakes (not hard enough to engage ABS, just HARD STOP) down to about 10 mph, (don't come to a complete stop) do this a few times (until you're bored of it). let brakes cool for a little bit, then do it again. should fix it - worked on my mom's chevy.

Had the same problem and still do. I keep my wheels/brakes clean with high pressure wash. The dealer told me that because I wash away all of the dust and oil that the brakes will naturally sqeak. Not sure if the dealer is being honest or just trying to placate me.

I had this problem and tried everything....washing the rotors thoroughly, not washing them at all, etc. Ultimately, I took it to the dealer and they replaced (pads & rotors) under warranty. I think it was both axels, too. Have not had a squeak since so something was wrong with the factory set-up from the git-go. I lived with it for 15K miles and now I have 45K miles and brakes are silent as they should be on such a fine car.....

According to my SA, the squeal is caused by the brake sensor. When the pads wear down, the sensor sometimes rubs against the brake disc. Dirt adds to the noise but cleaning the pads/disc is a temporary solution.

The sound usually starts when the pads are about half worn. The way to get rid of it is to change the pads and sensors. I didn't cause it still has at least a good 5 months of use left (They'll recommend changing when the pads are about 4mm).

However, I found that as I drove it more, the squeal reduced somewhat.

To add to the discussion, the dealer replaced my rear sensor and my rear pads. The rear rotors and everything in the front is original. I get major sqeaking after every car wash and then the sqeak fades over the next days. Additionally to the sqeak, when Im stopped and then just lightly lift the foot from the pedal, the breaks seems to grind and bark... Its not good. I imagine the fronts need to be looked at.

Everything you've described is exactly like my 645. From day one it's been like this, I thought it was normal..

Just called my SA the other day and he told me there was a "recall on bad sensor on 3's and 5's" and has to see if the same goes for the 6.

Any update on this matter? I know what 63 said is what really happening, so what is the solution?

I've had it since day one with the 6er. I have told the deale about 7 or 8 times now, and they just don't seem to want to do anything with it. My last 5er used to have the same issue every once in a while too...

I know how anoying it is to have to hear the sqeaks when you're pulling up to every single stop light, but I have learned to ignore it to a certain degree

I had the same problem. Plenty of pad left. After changing both the front & rear pads & sensors, the squeaking stopped.

Maybe I got lucky! The squeaking was driving me crazy.

The sound comes after the pads life reaches half way, thats when the sensors start touching the disks and the sound comes, it is just too annoying and it's also embarrassing, people think your too cheap to change your pads! so that leave us with no solution except to change the pads when ever they are half life! come on BMW find a solution for God sake.

Brakes

I had my discs changed under warranty at beginning of the year, about 7K miles. And for the last four months i have the same squeaking issue, a little touch and it goes thru your head. Could be the pads, however reading some of the comments above i will probably change the sensors too.

I complained about the brakes squeaking on it's 30K service and they replaced them all the way around. All was good until about 40K miles and it came back for me again. We'll see what they say next week.

Had the same sqeaky noise. Changed my pads all the way around at about 39,000 miles and the two front rotors. I'm at around 45,000 miles now with no noise. Will see what happens in a few thousand more miles.

I have the same problem on my 525i. The dealer says that they the pads are fine but I stated that my brakes should not squeak prematurely on an expensive car. We went back and forth and they went ahead and replaced the pads. They still squeak but I'm just dealing with it because I'm tired of going back and forth on it. It doesnt happen all the time now but it is enough to piss me off.

I had my rear brakes squeaking whenever I backup and also just before the car came to a full stop. I complain to the dealer and they replace the rear brakes for me. Then it start to have even grinding noise for a day or two, afterward, everything is back to normal (I would say after 200 miles ). Now, it's absolutely noise free

Yes this is exactly what it is, but does newer models have the same problem? if not can we fit them on our cars? I heard that this only happened on '04 and '05 models.

Same problem with mine......started at about 15K miles. After the 2nd trip to the dealer they told me it was driving habits. Unbelievable.

f**king squeaking brakes!!!!!

Im so gutted to read all these post about the brakes. I bought a 645 ci about 2 months ago, sure enough the brakes are now squeaking LOUD whenever I come to a stop.

I immediately took it to the mechanic who confirmed it was the pads.

I had the front & rear pads changed and the brake sensors replaced. No problems for about a week and now the noise is back even louder than before.

I feel like I am driving a bloody bus!!!! Not an expensive, stylish sports car.

I previously had a 735i and wish I had never swapped for a 6 at this point.

Does anyone have any other solutions?? I have washed them, greased them the works......at this point its going back to the garage to see if they can fix, but its not cheap and shouldnt be a problem on such a high end vehicle
