WD40

Edit: I'm kidding, never do that, ever.

 

Ya, most performance brakes will squeak a bit (i notice mine have always squeaked while coming to a stop from low speeds with light brake pressure). Had a similar phenomenon in both my STI's and my EvoX.

 

Same here, 1700 miles new and squeaks at low speed stops only. Had it back to the dealer to make sure nothing in the pads to score the rotor. Dealer check it out as normal. "Give it more miles and see what happens."

 

Mine squeak occasionally, but only in crawl speeds in reverse ...??

This has been discussed at length here before. Try searching for squealing brakes and you'll find more.

Apparently it's not a fault, but rather a by-product of over-sized sports brakes that are designed for heavy use but actually aren't being heavily used. The brake surface glazes over when you don't do heavy braking, which produces the squeal.

Solution - find a quiet stretch of road, speed up to around 80km/h (50 mph) and brake to a sudden stop. Repeat this a few times and you should be squeal free for a 1000km or so. It will come back, so just repeat.

 

Yep they squeak they make lots of break dust but they do stop really good when you need em too!

 

Here's another thread you can read through. Bottom line, take it in for service. If the dealership says they all do it, take it somewhere else. Squealing brakes are unacceptable, and shops who say they can't fix them are either lazy or incompetent....sad to say. Best of luck getting it resolved.

Sorry but I think you are being a little too dogmatic and are overlooking a few things.

If any shop ever tried to offer to fix my occasion lightly squeaking brakes for anything more than $10 and 10 minutes, I consider that incompetent or unethical.

An occasional light squeak under gentle braking that goes away is perfectly normal especially of the car is not driven hard, cosmetic and also doubles as an audible indicator of symmetry, lack of run out and healthy piston retraction.

Perfectly acceptable. But then I understand driving, mechanics and if not I can read the read the section in the manual or watch the Porsche video on noisy and dusty brakes and don't like getting fleeced.

There might be a good job for you in London fixing Taxi cab brakes.

 

I took mine to Porsche to have th brake squeal addressed. They warned me that unless I am harder on my brakes, the squeal (glaze) will come back. They removed the glaze and it is better than before, but I still get the occasional squeal.

 

Mine seem quiet so far, 1400 miles.
I hand wash the car & afterwards always drive a few blocks using brakes a lot to dry them off. I used to not drive after hand wash another car & got squeaky brakes.

"Why you get temporary brake noise after wet conditions"
Why you get temporary brake noise after wet conditions. - Club Lexus Forums

So, if your rotors look brown.....?

 

Brakes with a fine rust coating from a hand wash produce a rough rubbing / grinding noise and sometimes a loud low frequency resonance that goes away after a light braking. You only get that sort of fine rust on disks that get wet from hand washing and are let to sit for a short time to air dry. All perfectly normal and healthy.

Squeaking brakes are a different sound and cause.

 

I had squealing on my 2015 Turbo and my dealer replaced the rear rotors and pads. Nice and quiet now.

Im about 2300 miles in and noticed mine squeaking a bit recently. Doesn't really seem like a big enough deal to have it checked out. Besides, I do mostly city driving, and I just assumed it was because they don't really get any remotely hard use.

 

:|Mine have been squeaking since day 1 as well. Was told I am too easy on the brakes, Porsche is a sports performance car. I've taken it in 4 times and I assume they seat them (take it out and slam on the brakes a few times), squeaks go away temporarily and the next day, squeaking returns. I won't accept that it's a sports performance car, and that's just the way it's going to be. Taking it back in again tomorrow, just over 2000 miles now. Feeling like I bought a lemon.

 

Hello to you and sorry this has to be your First Post. My first week, the brakes squeaked too but I knew from driving performance Mercedes Benz's amongst others, it happens. Drive to around 25 to 30 MPH and step hard on the brakes a few times. Then do it again when the squeal returns, and it will. My problem went away and every once in a while brake dust gets back in there, I rinse and repeat. I wouldn't consider that a lemon car.

Do you enjoy driving it otherwise?

 

I love the car and very fun to drive! Just not fun to brake.

 

Try the braking thing I suggested before you take it back. There have been many posts on this you may want to search. I'm sure there are better suggestions from other members for bedding the brakes. Hope it works out for you. Welcome to the Forum.

 

I never hear squealing brakes. Must be the Burmester effect. Problem solved.

 

I haven't had this issue on our Macan yet but my intuition tells me it's dust collecting where it shouldn't. A few harder brakes should take care of it.

 

I have not had this problem on the Macan and I've had it for 1 yr. and 7,500 miles. I did have it occasionally on both Cayennes so I made sure I did the brake pad bedding procedure on the Macan on my initial drive home from the dealership. I'm fortunate where I live now that I can get up to 50 - 70 mph and brake harder on a fairly frequent basis and I don't do much city stop & go driving which I believe helps.

Also, when you do the brake bedding procedure do NOT come to a full stop, only slow to about 5 mph and repeat 3 - 4 times.

Good luck.

 

I had this problem from delivery till about 5000 miles. I haven't heard a squeal lately. Don't know if the weather has anything to do with it.

 

I am so disappointed with the squealing that I am willing to pay for ceramic brakes. I will ask the dealership is they can commit that ceramic brakes will be squealing free.

 

We are the buyers and the reason Porsche produces these vehicles. We need to be heard so that Porsche address our concerns and make us happy. I own a Lexus ISF with incredible brembo bream and no matter how I drive the car, the stopping distance and brake response is amazing, and of course it is free of any brake noises. Please Porsche brake performance is good but not out of the ordinary world sports car performance standards, so please no squeaks!

 

My Cayman GTS brakes squeaked until I bed them in

 

I take possession of our new S on Monday (exciting!) & I already have been warned by the dealer about the brakes squeaking.

I had exactly the same issue on my Audi - it started at around 20,000kms. It was more likely to occur in colder (& wetter?) weather & usually went away after a few minutes (again dependent on the temperature). The Audi service manager told me exactly the same story as the Porsche dealer - these cars are meant for hard driving & braking (isn't that great news??). Soft (for me - normal) driving/braking will induce squeaks. The Audi brakes were cleaned a couple of times during routine servicing & the squeaking always came back.

 

I also have squeaking breaks with my 335i occasionally when temperatures drop below 40ish. My remedy is to pick a curvy back or preferably mountain road and perform a short enthusiastic drive. That usually takes care of the squeak for the next 1000 miles or so. I won't be shocked if the Macan I ordered will have that too...I will gladly apply my solution as well. March '16 can't come soon enough

 

It will, but for me it's sporadic and not a big deal . Ok , sometimes it's a tad annoying but overall nuth'n but a thang.

I just brought my MY16 Macan S in for squeaky brakes (2nd time, first time I brought it in for a different issue but the SA heard my brakes as I pulled in and said they'd look at it). This time I was told that the brakes are meant for hard driving. Doesn't bother me most of the time, but sometimes they are REALLY loud and that's what gets me. Seems like a bad excuse if you ask me. Granted my X5 had terribly loud brakes in the winter months especially until the car warmed up a bit.

 

....This time I was told that the brakes are meant for hard driving.....

This is a common story. Here's the question that immediately comes to my mind. How do those folks explain the thousands of Porsche's and other high performance cars out there, that are not driven hard, and which don't have squealing brakes? Given that logic gap, the story is likely more myth than fact.

Here is what wikipedia has to say on the subject of disc brakes....under the sub-heading of Brake Squeal:

"Sometimes a loud noise or high pitched squeal occurs when the brakes are applied. Most brake squeal is produced by vibration (resonance instability) of the brake components, especially the pads and discs (known as force-coupled excitation). This type of squeal should not negatively affect brake stopping performance. Techniques include adding chamfer pads to the contact points between caliper pistons and the pads, the bonding insulators (damping material) to pad backplate, the brake shims between the brake pad and pistons, etc. All should be coated with an extremely high temperature, high solids lubricant to help reduce annoying squeal. This allows the metal to metal parts to move independently of each other and thereby eliminate the buildup of energy that can create a frequency that is heard as brake squeal, groan, or growl. Cold weather combined with high early-morning humidity (dew) often worsens brake squeal, although the squeal generally stops when the lining reaches regular operating temperatures.
Dust on the brakes may also cause squeal and commercial brake cleaning products are designed to remove dirt and other contaminants.
Some lining wear indicators, located either as a semi-metallic layer within the brake pad material or with an external "sensor", are also designed to squeal when the lining is due for replacement. The typical external sensor is fundamentally different from the noises described above (when the brakes are applied) because the wear sensor noise typically occurs when the brakes are not used."

https://en.wikipedia.org/wiki/Disc_brake

Bottom line; fixing brake squeal requires disassembly, cleaning, and lubrication of the metal-to-metal contact points on the calipers. I was taught this technique nearly 40 years ago, and have found it to be 100% successful on the cars I've worked on.

If your current dealership cannot solve the issue for you, take the car elsewhere. Also, be sure to give your previous dealership's service department an unsatisfactory performance rating on their customer satisfaction survey (if you get one).

You may ultimately need to find a good independent Porsche shop to fix it, unfortunately. Persistence is the key. Best of luck to you. It's very frustrating for you, I'm am sure.

 

As many there have stated performance calipers and performAnce brake pad compounds are the culprit. If you drive the car in a parking lot going 60 and pound on the brakes to about 40 and drive off it should be better, try it a few times. I have been told in the past coming to a complete stop is not necessarily good because you can potentially glaze the brake pads. In other words do not let the pads cool down immediately. All 3 of my Porsches have a squeaky brakes: 2010 Base Cayman, 2011 Base Cayenne and 2012 Cayman R. I assume my 2016 Macan S will as well. It does not go away but you will eventually get used to it, at least that's what I as told the first I complained about it as well.

 

So since my original post 6 months ago I've had squealing with both my Turbos. My last one which was the 2015 and my new one which is the 2016.

Here is the good news, both stopped squealing at roughly 2,500km BUT what I did was bed them in several times (on both cars) on an empty highway, late at night, and drove them relatively hard for about 500km after.

For the bedding process I basically accelerated to 100km/h and then used the brakes to quickly reduce the speed to about 20km/h (do not let the brakes fully engage -- do not come to a full stop) then quickly accelerated back up and did this about 10 to 12 times in quick succession. You will start to feel the brakes get softer towards the end and may even smell them, from my research this is apparently normal. After this I let them cool and coasted for about 3 to 4 minutes before fully engaging the brakes again. It's important to let them cool and not to engage them right away after this process which is why an empty highway is ideal. I did this twice on each car on different days and as mentioned above squeal and squeaks were gone by 2,500km, regardless of how I brake now.

Disclaimer: The above is not a substitute for professional advice, it's simply what worked for me. Don't be foolish and do it while other cars are around you. Do not blame me if you get a ticket trying this.

 

The brake squeal is unacceptable. My dealership made good and called to obtain approval from Porsche to replace my rear brake hardware. That was done around 10,000 miles. Now, at 15k they continue to be nice and quiet. You need to press and get the repair done. Don't accept BS answers! If it was normal all Macan's would be making noise.
