Brake squeaking going in reverse

Like the title says, my car's (2007 335 coupe) brake squeaks when car is going in reverse direction. I took the car to the dealer and they said it's due to normal wear and tear of the brake so they just cleaned the brakes but the squeak is still there. On board computer says i still have about 9000 miles to go before i need my front brake replaced and 12,000 miles to go for the rear brakes. My question is, if the squeak is due to normal wear and tear, shouldn't it get replaced by the maintenance plan??

If you have 9,000+ miles to go on the existing brakes, why should they be replaced? Good luck convincing BMW that your brakes need replacing with 9,000+ miles left on the pads.

If you don't like the brake noise when driving in reverse, try not driving in reverse.

I'm guessing you either 1) don't ever have to drive your car in reverse OR 2) your breaks don't squeak when your car is going in reverse

either way, breaks shouldn't squeak regardless which direction the car is going, and I was wondering if there are any other drivers who have faced a similar situation as I have, and wanted to know what those drivers did to mitigate the issue.

If you didn't have any valuable input to provide to me, why bother wasting your time typing a response?

Well..., I did wish you luck in your attempts to convince BMW that your brakes need to be replaced with 9,000+ miles of wear left on them....

BTW, how long ago did you learn to drive? There was a time not too too long ago, where disc brakes made noise when the operator pressed the Stop pedal regardless of whether they were driving forward or reverse. But that may have been before your time.

I wonder why no one else has replied to your post? Probably its the holiday weekend. Brake noise while driving in reverse has got to be at the top of everyone's list of issues with their cars - even ahead of HPFP failure.

I had the same issue and my BMW dealer replaced my breaks no questions asked... As soon as they heard it.

Edit:
I forgot how many miles were left on the pad's per the computer, but the card had 26k miles on it so?? I'm sure you can figure it out based on your current mileage.

I feel like all depends on your dealership with any repairs being taken care of or not. I must just get lucky.

Maybe your dealer did in fact give you a break.... Although depending on how you drive your car, 26,000 miles could be in replacement (due to wear) territory.

I had the same issue and a friend suggested that it might be a small rock between the rotor and pad, but because it only does it in reverse that it was probably one of the rear brakes. Sure enough it worked itself out of there that day and hasn't made a peep since.

I would give it a day or two and see if it is a rock that needs to be worked out.

happens to me a few times a year. doing "bed in" again fixes the problem for some time. If it's rear brakes, it might also be parking brake - similar(but way slower speed) bed in can be done.

Sky has a good point. Let's assume that since the squeal only happens in reverse that the pads are not excessively worn.
Here's what we would try at my shop. Drive in reverse in a large parking lot. Make repeated stops -10 or so- from full reverse speed. Then drive in reverse with your foot lightly on the brake pedal so that you can feel your car just begin to slow down. Drive 100 or so feet. Then drive forward to the start point. Then drive in reverse lightly dragging the brake as before. Do this 5 times. Following this procedure drive normally for a mile or so to ensure an even cool down. Do NOT apply the parking brake until after you cool down.
Old mechanic's trick. Kids don't know this stuff. It isn't in their textbooks.

Good advice!

As far as replacement, the dealer can replace them at any time, if they find a problem. I had the wheel squeak problem (forward/slow) and the dealer replaced my pads/rotors and I haven't had a problem since. I don't remember my mileage, but pretty sure it was < 12k.

Good luck with this, I know squeaks drive me crazy...

Big thanks to all who shared their experiences. My dealer said the noise is normal, and below is the note that they had on the work order. Please let me know if my dealer is talking nonsense here. Because I am wondering if I need to do a better job of convincing them to replace my brakes.

"Normal operation light squeaking in reverse is normal due to normal wear pattern of brake friction material. Deglased brake pads. Front pads measure 10MM Rear 8MM"

Thank you, I will try this out.

Do you know how you "deglase brake pads"? You remove them and sand them with 220 or 100 grit sandpaper. Sometimes that works. But NEVER if a customer complains that the car only squeals in reverse. Sheesh.
