35i with Msport brake squeal

300hp · 06-12-2015, 05:24 PM

Does your 35i Msport experience loud front brake squeal. I thought it was the bus or train making that sound until I realized it was me. Lol.

There are several tsbs out for that involving getting the brakes replaced. That did not work so going in for the second round

Edit:
I should add that mine is a 2014 with the stnd msport brakes (I think they are the same as the sport line brakes)

My M Sport brakes squeal also, only 3kmiles driven so far

Mine did when the seasons changed from winter to spring and now it doesn't.

200 miles on my 335 and the brakes couldn't be quieter. I hope it stays this way.

I get a random squeal every so often. Getting to 12.5k miles of driving pretty hard lol

Mine only started last week. About the same mileage as yours. This squeal is loud and very unpleasant. It's distinguishable from the winter squeal. Mine squeals after the brakes have warmed up.

My brake pads got replaced after I took it in to get this resolved and within 15 miles of driving the squeal was back. Getting a loaner so they can figure this out. I am losing a lot of gas as they test drive my car, haha

There was a bulletin a year or so ago that required replacement of the caliper brackets as I recall. Once that was done, my squeal went away.

I think that's what I need since the pads didn't work.

My car is new, built in 2015 delivered end of March, but sequels. It is not present all the time but only on few occasions

There are several tsbs out for that involving getting the brakes replaced. That did not work so going in for the second round

Edit:
I should add that mine is a 2014 with the stnd msport brakes (I think they are the same as the sport line brakes)

When mine was new it did the same thing-- I though it was quite obnoxious pulling up to a stop and sounding like a bus too. HAHA However, after a few K miles, they are silent.

**2013 with standard 335i brakes and M-Sport pads

Lol, I know right. It took me a while to accept that it was my car making that noise. Haha. It was too loud for a small car
