Brakes Squealing AGAIN even when warm.

obert · 02-17-2017, 10:39 AM

Dropped mine off for some service this morning and the SA said they would de-glaze the rotors. He said what he does twice a year is goes in reverse and hits the brakes to de-glaze the rotors.

Sounds like one of those deals like your blinker fluid is low.

I go in reverse everyday and hit the brakes. This does not work. Unless he talking about doing it for a long period of time. Idk what going in reverse would really do differently.

I agree. I thought it was funny for him to even suggest that.

I think that SA is caught in old school drum brake land thinking. Back when cars had drums, backing up in reverse, and cranking on the brakes would force the brake shoes in the drums to ratchet out to take out slack. Disc brakes eliminates that issue.

There is no way you could de-glaze a brake pad with a couple hard braking procedures in reverse. Now, if you do a couple 60-0 hard braking stints, then sure.

The real issue is dust is building up and the pads aren't floating properly. Hard braking will help buy knocking some of that loose.

obert · 02-17-2017, 04:36 PM

They put anti seize and squeal on all the pads and cleaned everything.

My wife has had an issue like this with her S3 for a long time.
Car has less than 2k on it and when coming to a complete stop the car violently shakes.

Shaking is a sign of warping

and this is what they did
replaced the front with "updated pads" and cleaned the rear

ask your service advisor about it

i have the blue M sport brakes

Took the car in for real fuel pump recall and this is the exact repair they did to my front brakes. It has been rain for a few days and I can't really tell or test the vehicle for squeaking noise.

SA said BMW wanted to reclean the brakes again. He said that's a waste of time since we have done that, SA wants to replace pads and rotors once again. ...I'm just being as nice as possible, since it's not his fault. he said stay tuned n have me the 335i GT to keep for the weekend. active spoiler, nice!

That's whats weird they replaced our F&R rotors and brake pads. We don't even have the car right now currently still in dealership for this issue that they say "Oh we still can't diagnose the issue. Take the car home and we will contact you"... We love the car but not right now.....

p30amg08 · 02-21-2017, 08:12 PM

update.

the dealer said because the brake pads and rotors are new all they can do is clean and Lube them. they will not be replacing them again If i want them replaced I have to pay out of my pocket.

I asked him to check the battery since it was 4 years old and they went ahead and replaced that under warranty...

so I guess BMW is not willing to repair squeaking brakes. I guess the clean and Lube worked for now since they're not squealing anymore

obert · 02-22-2017, 04:25 PM

Mine are back to making noise. I will just deal with it until its time to replace them. I will go with a aftermarket pad and rotor.

I swapped my pads for EBC red's and no more noise. Better pedal feel, and better braking (no more dust and no squeal as well).

Swap to aftermarket, and you won't look back....

Thanks for the info.

These pads look brand new. I be saving some money for new brakes

Wires · 02-23-2017, 09:30 PM

No problem. I have a set of "mint" OEM pads in the garage.

eluded · 02-24-2017, 01:52 AM

So my brakes of started squealing. Extremely annoying. I think it's gonna drive me crazy. I rarely use the brakes & car only has 5000 miles. I'm sure this is normal. Don't notice it with the stereo turned up.

XKxRome0ox · 02-28-2017, 09:35 PM

so i think i got about 2 full weeks with the "updated pads" without any noise ... but now i'm starting to hear some brake noise again
is there really no hope?

Billfitz · 03-01-2017, 09:11 AM

The pads and calipers weren't properly lubed. What lube there was wore off, the noise came back. Shops just don't take the time to do it right, because time is money, and they get paid a flat rate for the job.

p30amg08 · 03-01-2017, 09:13 AM

mine is back again slightly again. calling my attorney. this is just unacceptable. now that bmw acknowledged there is an issue and wont fix it, i want to know my options.

tegraphile · 06-06-2017, 01:13 PM

Dealing with break squeal on a CPO with 32K, started at 27K when I first got it. Taking the car in for an oil change, so we'll see if I can replicate it and get them to do something about it.

I do notice it is most likely to start happening when I engage in a few aggressive decels and then follow it up with low speed, mild slow downs.

Lube the calipers and/or replace the pads with non-OEM. Cheaper than your laywer....
