Brake squeal [Video]
Now I know brakes can squeal from time to time but for the past 6 months, the brakes on my M235i have been making this horrendous sound around the clock whenever I drive the car. I've told my service advisor about this and they replaced the brake pads but said that this is a common problem with these brakes and that these brakes cause a lot of brake dust so there was nothing they could do. Any help is appreciated, thanks in advance!

Brake dust yes but that squealing unusual unless your getting the pads very hot and doing repeated hard stops from 130+ down to 0.
I wonder if they really replaced pads and if they used brake pad back side anti-vibration paste. I had a new Benz took it in for brake squeal they told me they looked at it and when the noise continued did the brake work myself and found a pad that had fallen out of the slider channel - that was Mercedes of silver spring and they did shoddy work.

Annoying Brake Squeal
Quote:
We bought the car as a CPO in April with 28K miles on it so we haven't driven it that much in the time we've owned it. Did you ever get the squeal resolved, and if so, what was done to fix it? Thanks. |

Improper/inadequate brake paste would be the first culprit - if SFCA is as sandy as Monterey was, you might also need to really clean things up to get rid of the old paste and grit. But assuming you have already had them apart and re-lubed w/o benefit, try truly bedding in the brakes before changing more parts (unless you can get BMW to spring for the rotors). You need to find a long open stretch w/o traffic, get up to 60-70, then several cycles of hard braking down to about 10, then back to 60 and do it again (I'd go at least 5 cycles; avoid activating ABS but as close to that as you can get). No full-stop during this, drive a while before fully stopping, and don't use parking brake for at least an hour.

I should note, when we bought the car in April 2019, there was no squeal. It started in August and has gotten progressively worse... |
