I have 3800 miles on my 2017 and my brakes just started squealing after I have driven around for awhile. Has anyone else experienced this? Should I take it back to the dealership and have them look at it?

I believe this is common on more do it than not. I may be wrong but I think I've read that it has something to do with those Brembo brakes and the pads that put out a lot of brake dust. Also I may have read that ceramic pads will stop it. From what others have posted don't believe dealership can cure it. Some one will chime in with more info.

Mine have squealed since day 1. Worse once warmed up and under light in town braking conditions. I did "bed them in" when I first got the car as well. I've heard from others that the dealer will likely install new pads which may or may not cure the issue. Check out Auto Fanatic's You Tube channel, he's got a cure by applying disc quiet to the back of the brake pads. I'm going to do this to mine one day soon and will post. Back in the day this was a common fix for squealing disc brakes.

Good luck!

Same here as HotLap, and everyone else. My calipers are off right now for paint, so I'll do the anti-sieze on the pads for reassembly...until my EBC Red pads come in. That'll eliminate the dust.

Mine started at about 350 miles. I took it to my Dealership and they cleaned the rotors and pads. They, of course, couldn't really find anything wrong. They did not replace the pads. So far, I have 3700 miles, and the squeal has not returned. I thought I heard it once or twice, but that was it.

Yep, they squeek. A hard mountain drive will make mine quiet for a few days, then it comes back. Use a pressure washer on brakes to clean out imbedded dust. Welcome to performance brakes!

Mine has had a light squeak under gentle braking since mile 1. It never bothered me enough to look into it. I just assumed massive pads and rotors cause more friction. Seems thats the consensus as well. It also looks like Ill be looking into ceramic pads for replacement when needed.

Has anyone tried ceramic pads yet? I hate pulling into my neighborhood and my brakes just squeal away.

I pulled my pads last weekend, and cleaned the heck out of everything, calipers etc.. The previous owner hadn't had them apart I don't believe. Put a little copper brake grease on the face of the pistons/back of the pads. Not a peep since. I seem to have to do this once every few years on anything with Brembos I feel like. My Thruxton R was the same and I fixed it the same way. Just pick up a T60torx bit and some blue loctite and be sure to re-torque everything and it is easily done in an afternoon.

I went ahead and did both. The rear pads don't even require removing the caliper so no reason not to. Tap out the pins, pull the spring, and push them from the axle side out. They go back in the opposite way. So no need to fiddle with the parking brake etc. I would also recommend this as being a really good time to seal or wax your wheels inside and out. I used jetseal from Chemical guys personally and this week's wheel cleaning only required a hose. MUCH easier than when they weren't sealed.

do you use any particular brand of copper brake grease?

This is what I use.

It's handy to have around in general honestly so I don't mind the larger size. It's also handy to keep exhaust parts from fusing together as well. My fastback has a thin layer at every exhaust joint as well as on the o2 bungs.

EDIT* just as an update it's been a few weeks since I did mine now of daily stop-n-go LA traffic and not a peep out of them since I did this.

For anyone coming back to this page in the future. Here is a mildly pretentious Porsche video on the topic that sums up brake squeal with high performance brake rotors and pads.


moral of the story, brake pads vibrate at low speeds and the rotors act like a speaker.

Different rotors will have different common frequencies that produce a squeal. The brake lube put on the back of pads works because it dampens those vibrations thus helping to minimize or eliminate the squeal. Different pad material may vibrate less which is why some people see a reduction in squeal when they change to a new pad.

This is all completely normal and will just come down to whether you can stand the squeal or want to "fix" it.

Side note, when I bought my 350, I told them about the brake squeal and asked them to put some brake lube on the back...the guy just mumbles under his breath something to the affect of "that won't do anything" and proceeded to shave the rotors instead, which helped for a bit, but was not a more permanent solution.

These brakes squell at low speeds, especially as the brake dust builds up. But once I clean the wheels with one of those wheel cleaners designed for our wheels(non-acidic), the squelling goes away for awhile. Once I see the wheels getting covered in brake dust, they start squellng again, and then it's time to clean again.
Btw, at the GT350 track attack, I noticed after the afternoon of driving around the track(about 20 laps total), I noticed the wheels had harly any brake dust on them. Certainly way less than when I drive my car around ton. I asked the instructors as to why? They said at the high spped we're driving, most of the dust is blown away from the wheels, and doen't have a chance to collect as much. So my conclusion is driving fast=less brake dust. :giggle:
