Brakes Squeling
Hi guys, i have annoying brake squeal. The service writer at BMW Ftlauderdale told me it's a common problem with M cars, but how is this acceptable? I love the car but the brakes make me feel like im driving a beat up old car.

Mine sometimes sounds like a train coming to a stop which can be embarrassing. There are many threads stating that this is normal.

Normal per technical training documentation.

Mine squeak on cold days too, but not terrible. Not nearly as bad as my wife's M2C did in any temperature. We pulled her brakes apart and re-greased, they are good to go now.

How do you like the brakes on your F87C? For me, they felt more grabby and maybe too sensitive.

Had my car for just over a month but this weekend the brakes started to squeal pretty bad.
Sounds like a train coming into the platform.

Some 150-0 stops, and the brakes wont make any noise. I have 3,800 miles on my 22 xDrive and my CCBs don't even make noise, and they're the ones that are known to be bad with brake noise. Get a pressure washer, or go to the magic wand car wash, and pressure wash the rotors off. Get that trapped brake dust out of there, making sure the drilled holes in the rotors are cleaned out. The rotors get a glazing over them if you don't drive them hard. You have to knock that top coat off of the rotors, every once in a while. The brake dust gets trapped between the pad and the rotor, like taking a beer bottle, and blowing across the top of it, creating the proper pitch, that makes sound. Knock all of that shit off, with some solid stops.

I wanted to bang my head against my windshield as I listened to my £100k car squeal like a banger in town at the weekend at every light or junction. It's great that your over it but maybe other aren't at the "bang my head on the desk" stage just yet. I think we've all asked questions on this forum that soon became stupid, boring, already answered a million times or whatever. Show some love and take pity on all of us who have poor man's rotors 😎👍

I'm literally going through the exact same thing with my 300 mile G83. This isn't my first M car and none of them have squealed like this one - it's embarrassing. I set up an appointment with my dealership but if all they're going to do is tell me "it's normal" then I won't waste my time.
An earlier post mentioned "grease the pads" - what does that consist of? |

Took this pic of the rear brakes but the fronts are the same. There's some black shit (the glazing, I assume) on the rotors. That's what needs to be knocked off.

It's one of those things where you have to have either one, or the other, but not both. Do you want the brakes to stop in 96 feet from 60, or do you want to get less dusty pads, and have the car take 110-120 feet to stop from 60? Brembo chooses to stick to the 96 feet, and BMW put them on your track car, for that reason. If you want quiet brakes, we could all just get an 330i.

I did that exact thing - several hard stops from 60-70 mph. Have only experienced lower speed squealing now. I have more work to do but a huge improvement.
