Squealing sound when lightly pressing the brakes

BentZero · 04-06-2016, 07:11 AM

Yesterday when I pulled into the lot at work I heard a squealing sound coming from my brakes. Kind of like the brake wear indicator sound. It only happened once though. This morning I heard it again when I was in a bit of traffic and again when I pulled into the lot.

The car isn't even a month old. :/ Anyway, is this covered? Should be, right?

Squealing is normal when coming near a stop.

Try a the following to remove possible light glazing on rotors: drive on a road with no traffic, at 60mph aggressively apply brakes (but don't activate abs) to a speed of 20mph. Accelerate up to 60mph and do it again....repeated 3- 4 times. Your brakes will be quite warm so drive a few miles without stopping to allow them to cool off. This should remove any glaze on the pads/rotors. If you still have the issue check w/dealer.

After 1,500 miles you'd think that brakes would already be broken in though. :/ I'll give this a shot tonight. I have the perfect road to do it on near my house. Thanks.

My wife's Merc had a similar issue. It ended up being some spring or something that's supposed to return the pad to the original position, but it was malfunctioning with low speed/light braking. Basically similar issue in my car. Also, it just started happening. Driving habits haven't changed. Doesn't seem normal to me.

I've had this on all 3 of my cars. Seemed to be temp related but anytime I mentioned to my service guy they lubed the brakes and the squeal disappeared.

Viffermike · 04-06-2016, 09:21 AM

My car has nearly 9K miles on it now, and it still squeals lightly at times -- even when the rotors are warmed. Based on other threads, it partially has something to do with the OEM pad compound.

Also, don't feel too bad about the squealing ... I had what I think was a small pebble lodged in between my rotor and the pad in the middle of Big Bend National Park a few weeks ago. It made a horrible screeching sound -- only going forward, not in reverse -- and I initially thought I had a serious problem in one of the Continental U.S.' most remote NPs. A hard application of the brakes at about 15mph dislodged the pebble ... and my butt unclenched.

There is variation on this. Two years in, and never a squeal so far.....

Interesting. I wonder if climate has something to do with it; humidity, etc ... I don't have the THP, so it could also be that -- though I'd imagine the M Sport fixed-caliper brakes likely have a slightly more aggressive compound than the standard floating calipers ... ?

Climate may also be a function of my car spending every night in the garage. I do see some members appear to park outdoors. But, even on cold days at work, I have not heard a squeal after sitting all day. Squeal also can relate to the proper application of grease during the pad installation.

As far as aggressive pads, I am also surprised at the low level of dust on the MSport brakes.

BarryJI · 04-06-2016, 09:40 AM

From what I've heard it's fairly commonplace.

That's a great point. I park in a covered garage, but it's open to ambient outside air and not climate controlled. Hmmm ...

BentZero · 04-06-2016, 10:09 AM

Man, the fact that it's common is disappointing then. I find it to be embarrassing. :/ I'm gonna call the dealer on the way to the gym and see what they say.

Mine is garage parked at home and work. I have brake squeal when I first get going nearly all the time with light pressure. Goes away once things warm up. I asked about it at one of my service appointments. They said it was normal for "high performance brakes".

Maybe I can't do "light pressure"!

But, seriously, I've had squeal in other cars of this caliber, but not this one. I cannot explain it.

BentZero · 04-06-2016, 10:38 AM

Well, dealer told me to bring it in Tuesday and they'll provide a loaner. Gotta use some of my time, but oh well.

Low? My wheels are literally covered in dust all the time. Within a few hours of cleaning them they're all dusty again.

Hmmmm....between noise and dust, this is starting to seem as if there was a pad formulation change at some point in production.

Mywifes335 · 04-06-2016, 11:44 AM

Honestly, if fewer people complained about brake noise and dust, our cars would be equipped with much better performing brakes.

Compared with pre-2011 vehicles, current non-M compounds are weak sauce.

Crap......my wheels get dusty too which I can deal with. I can deal with noise too if it means better performance. I shouldn't have complained. I've failed us!!!

EternalVendetta · 04-06-2016, 12:45 PM

I hear this occasionally as well with my 2016 M235i. It's a minor annoyance, and thankfully it doesn't seem to happen often.

bimmerfile · 04-07-2016, 12:07 PM

My brakes only squeal when the temperature is below -2 Celsius (28F)..
