Brake Squeal - Do you have Brembos?

[FordTechOne]

First off this is not intermittent noise. It can be duplicated every time with slow speed rolling turns. Not sure where you got intermittent from.

Not sure where you got the attitude problem from.

I never claimed that the brake noise you describe was "intermittent". I said if you have the Performance Pack and you have an intermittent brake noise, that's a normal characteristic.

Second if you read this thread it seems most of the complaints are coming from GT owners WITH the performance pack.

I'm not concerned with "complaints", I'm concerned with actual issues. The majority of GT models with the Performance Pack are going to have some intermittent brake noise. That's the nature of high Performance brake systems that are track ready. If you don't want any brake noise, don't buy a vehicle with high performance brakes. It's that simple.

Third I've called 3 different dealers and have been told TSB 15-0030 is for 5.0L and 2.3 ecoboost cars WITH the performance pack only. I do agree that if you read the language on the actual TSB its says "and" and then it says "or" making it somewhat open to interpretation if the 5.0L is included without the PP. The key here is that it says "4 piston brake calipers". I honestly don't know if the PP pack has the option to only gets 6 piston or not. I would love for a Ford Rep to clarify this.

I'm not sure why I'm even trying to help you at this point based on the previous comments you've made, but the fact of the matter is that TSB 15-0030 applies to Ecoboost Performance Pack models and GT non-Performance Pack models. The reason is that they use the same exact brake systems. All GT Performance Pack models have 6 piston Brembo front calipers. It's not an option; if you get the GT PP, you get the 6 pots.

May I suggest you try going to the dealer you bought the car from instead of calling random dealers on the phone. When you call a service department you will typically get a service advisor, who may or may not know what the hell they are talking about. If you actually go to the dealer and verify the issue with them, there is a much better chance they will take care of it for you.

Lastly, if you read the threads on this subject on this site and others there are many people complaining of this issue with GT and eco boost mustangs with or without the performance pack. Its obviously a know problem across many models. The only exception being the V6, but even they have a few complaints.

There is no "known problem" Mr. Conspiracy theory. There is simply a TSB to address a brake noise issue that affects some models with 4 piston calipers. You seriously need to get a grip; you're going off the deep end with your own nonsense.

You better go back and read it again the part where it says 4 piston caliper. GT PP car has 6 piston calipers this TBS doesn't apply to you.

I get brake noise from time to time so what part of having performance brakes. Amazing part people want high performance then want this luxury ride and dead slight car can't have both people.

I think people are reading the verbiage on the TSB where it says (if I recall specifically) 5.0 and ecoboost models with performance package". It makes it sound like both have the PP but it's actually saying "the 5.0" and "the ecb with pp". not "the 5.0 with PP" and "the ecb with PP". Someone is probably looking it up when he calls and interpreting it based on that verbiage without actually reading the description. It would be an easy mistake to make. I've never had a dealership actually know anything about stuff like this until I bring it up and prove it. I guess they can't know everything about every vehicle even if they sell that vehicle. I think we all have that expectation, and it's not unrealistic to feel that way. My wife bought a used Acadia a few years back. We test drove a different one at another dealer a few days before that and when we got back from the drive I shut it off and took out the key. Then I noticed it was still running, and it continued to run for another 20 seconds or so. Obviously we weren't gonna buy that one, and I searched and found a recall for a sunroof leak that was getting into the fuse panel. When we bought hers a week later (from a GMC dealer), I brought it up and they had no idea, but did go confirm that hers was manufactured after it was corrected. I feel like all this stuff should be queried beforehand. It only took me a couple minutes with my phone and without the internal resources a dealership would have, but at the same time I just don't expect anyone to even actually know what they're doing anymore.

I DONT have the PP. It should apply to me.

Exactly. There is a contradiction in verbiage on the TSB. On the header it says 5.0L AND 2.3L ecoboost PP. Then right below it says 5.0L OR 2.3 ecoboost PP. I can see how the service reps are reading that wrong and concluding its only cars with the PP.

The key here is if you keep reading it says "These cars are equipped with 4 piston brakes". The non PP GT cars have 4 piston brakes. So the TSB would apply.

When I have a day off I'm going down to the dealer with a copy of the TSB to show them. Hopefully they can read for themselves.

I don't expect anyone in this world to know how to read either!

That's why you have read whole thing not part of it

I dont know how true this is but ford told me if you wash the rotors when they're hot it might bend them and cause squeaking

Generally it's not advised to spray cold water on very hot metal. It can cause the component to deform or crack. As far as squeaking, never heard it causing that, but if the metal has been compromised I could see it causes a bunch of issues.

I have PP with Brembos and thought I had an issue, very loud noise under light braking.... I eventually determined it was actually coming from the rear brakes. I also discovered that after I torqued the lugs uniformly to the factory spec 150 ft/pounds that the noise mostly went away immediately, and eventually went away all together, I haven't heard it in a couple months.

150 ft/lb?!?!? That is crazy tight for wheel lugs. My past performance cars all called for something closer to 80. From where are you getting that spec?

Mine just started screeching like a 40 year old school bus. I only have 12k miles on a GT PP.

6 piston fronts, 4 in the back i believe

I'm pretty sure the rears are single piston.
