Squeaky brakes

yeah_knee · 04-06-2022, 12:32 PM

Talk about some SQUEAKY brakes... my f10 m5 wasn't this bad. I'm changing out the rear brake pads to akebono, but the only brand offered for the front is Bmw oem pads. I can't tell it the squeak is coming front the front or back brakes, but they're so damn loud even on light press going slow. Anyone else have experience with this? What was your solution, if any?

What BMW are you talking about? Would help with responses.

Might be time for new rotors, if their surface feels anything but mirror smooth it's a good chance they are the source of your brake noise. 7-8 years on original rotors is a pretty good life length. Aftermarket ceramic pads are more likely to whine, and you can also dampen whine with CRC Brake Quiet - which cuts down on the pad vibrating.

Brake noise is normal for M cars. Here's a video from Porsche explaining why.

Maybe do the pad bed in procedure?

Get used to it?

Drive harder / Change pads to something meant for grocery getting / Swap the M for the base version?

Please help. I have a 2022 BMW M8 comp and the squeak is so bad. I even escalated the problem to the main office in New Jersey and they basically told me to kick rocks. I’ve taken to a couple different dealerships for service and they just tell me it’s normal. The main office said they can only Lemon it out if they tried to do maintenance on the vehicle, but they just send me home. I have tons of videos but I do not know how to post here.

. There is no long term fix. My 2016 and 2019 X6Ms squealed like an old school bus. It was worse than nails on a blackboard. There are a bunch of threads in the F85/F86 forum on the squeaky brakes. Some change out the pads but the noise returns.

My 2018 F90 M5 used to squeak quite a bit. Some high speed breaking usually fixed it. Maybe that'll work for you too.

I park near the ocean and in the morning there is a mist in the air. Whenever I first back out of my outdoor parking space my brakes make a sound. As soon as I start driving and apply pressure to the brakes the sound disappears.

Brakes should not generate unusual sounds under normal circumstances. Focusing on the most common sound: squealing / squeaking.

Eliminating one of the unusual yet common reasons: sometime the brake pad sensor is installed incorrectly. So plastic rubs over metal and that's what one hears. Worth checking first.

While braking, the brake pad meets the rotor surface, loses a thin sliver of the brake compound, creating brake dust.

That's where conditions which contribute to the eventual brake squeaking symptoms converge: weather (moisture in the air), heat, driving style, rotor condition, brake pads compound (from softer to harsher). The goal however is the same: how to minimize the brake dust binding to the rotor surface.

Every driver operates in a different environment. The brakes on my BMW vehicles never squealed. I always used OEM brakes, mainly because I prefer aggressive initial bite of softer OEM brake pads which do produce brake dust - a sign that brakes perform their job well. But smooth BMW OEM rotors may not be suited for every environment.

How to minimize the brake dust binding to the rotor surface:

- Reduce rotor surface temperature
- Use drilled / slotted rotors; slotted rotors help shave the surface of the brake pad and prepare a fresh layer of brake compound for the next braking cycle. Drilled rotors also allow the moisture and brake dust to escape

M Performance dimpled rotors are not as effective as drilled / slotted aftermarket rotors. Do not buy these rotors.

In summary: get a new set of drilled / slotted rotors, new brake wear sensors, a new set of OEM brake pad (softer compound is more desirable with slots).

Then - bed the brakes properly and enjoy hopefully fewer brake noises.
