I have a 2015 V6 3.7L Mustang that makes a loud squealing noise when braking, mostly when braking at low speed and occasionally at higher speeds. I have taken the car in for servicing 3 times, but they can only partially reproduce the problem. There is a TSB for this problem that applies to ecoboost and GT models.

Has anyone else experienced this issue?

 

I have a '16 GT Premium PP and yes I've had this problem. The only thing that has helped for me (and got this from what others on the forum have experienced) is to do a run where you heat up the brakes. Do a couple hard stops from highway speeds to zero in a row. This has stopped the squeaking for the most part. It comes back sometimes but I repeat the process. Hope this helps. I doubt it's a "professional" fix but it helped me.

 

Thanks, Coyote. I have tried this and it works for a few days then it returns. BTW if you have a GT there is a TSB 15-0030 that you may want to look at. Unfortunately the TSB does not apply to the V6 3.7L model.

 

i have the same issue, 2016 mustang v6 auto, front brakes squeal at low speeds. First heard it around 400 miles. I have noticed that it squeals a bit less now at 1200 miles, but it still does squeal.
