brake noise?

brake noise?

Am experiencing some squeak as I approach complete stop. Squeak is not audible until the very end. Anyone else experiencing brake noise. FYi - overall stopping power of the brakes is impressive

I'm seeing that as well and have seen a lot of others report the issue. Might be worth doing some power braking to try to break in the break pads.

A few 60-0 runs should do it! Maybe once a month, to keep the rust out? ;)

Mmmmmmmmm ..... Power breaking.

I heard the squeak after about 100 miles. Since then I had to brake hard a couple of times during traffic. I haven't noticed the squeak lately.

When it occurs, think of it as a warning tone for pedestrians.

Think of it as a plea to be given a workout!

I had the same problem when I replaced the brake pads on my BMW. It went away after several hundred miles of driving.

A bit off topic, but since we are talking brakes, Does the Model S use brake fluid?

I had a squeek for about one hour after a few hundred miles. The tech suggested that something, maybe a small rock had lodged in the brakes. I have yet to see rust or any other issues. I seldom use the brakes except at very low speeds.

I've had a slight squeak since I picked it up at the factory a few weeks ago. Still there today, with daily driving and something like a few hundred miles on my odo. I had chalked it up to a "new car" thing, but it occurred to me yesterday that no prior new car I've owned has had breaks that hummed/squeaked when new.

Brian H | November 15, 2012

They're still unused! Try a few 60-0 braking runs. Or turn off regen for a day or two.

Please..."brakes" stop the car, breaks don't unless it is a really big break!

Brian H | November 15, 2012

Yep, as in, "The brakes chose that moment to break so I had to brake the car by breaking it up against a tree."

sergiyz | November 17, 2012

I have over 1,400 miles on my odometer now and tried pretty much everything, including driving w/o regen and using "power braking".
If it doesn't stop by 2,000 miles, I'll take it to Tesla again.
They've tried re-seating the pads first thing, it didn't help.

Brian H | November 17, 2012

Sounds like you're on track to track the source! Please keep all informed of all the steps you've taken, so everyone isn't reinventing the wheel, so to speak. ;)

Yes. The brakes are just standard Brembo brakes. The only difference is that the power brake pump is electric rather than hydraulic.

Afilm_Guy | November 17, 2012

Tesla has known about brakes squeaking since the get amped event at the factory for sure.
Check out the videos you can hear the squeaks pulling up to the people.

My car is squeaks as well very unbecoming of a vehicle like this.
Are they going to take this seriously?

Perhaps we need a bigger thread?

stephen.kamichik | November 17, 2012

TM may have to change the brake pad material to eliminate the squeaking.

StephRob | November 17, 2012

My brakes squeak too. Usually happens when the car is almost at a stop. Most often happens when breaking downhill. It may just be an acoustic illusion, but it seems to be coming from the back wheels and predominantly from the passenger side.

jerry3 | November 17, 2012

There are some reports indicating the squeaking happens less frequently and perhaps goes away entirely as miles accumulate. If that's true, then it's just a function of the pads seating fully, in which case a few 60-0 stops should fix it. Note that if you use this method, drive the car for ten to fifteen minutes after the last 60-0 stop. There are some posts on this in the Roadster section of the TMClub site.

Lemons to lemonade! Perhaps the brake squeal is a TM, safety feature built in to warn pedestrians that a silent but deadly EV is stopping.

Brian H | November 17, 2012

Here's a post excerpt from TMC on the subj.:

I don't use the brakes enough and so when I do need them they squeak embarrassingly. Even after a day of hard braking at Laguna Seca, they were back to squeaking within a week.

So, it appears they need to be used reasonably often ...

Brian H | November 17, 2012

Maybe EVs need "softer" pads, that wear more easily, instead of resisting noisily!

Velo1 | November 17, 2012

Squeaking brakes is a stick-stick phenomenon, generating molecular surface vibration in the metal components. The best remedy is a different brake pad material, with less Shore D hardness. This is a classic acoustical issue (think railcar retarders or brakes).

TM should work with their brake supplier to come up with the optimum material. Bottom line: that new brakes should never squeak or squeal, it is worn brake pads that makes noise as they become harder.

Brian H | November 18, 2012

;) Like I said, softer.

Velo1 | November 18, 2012

^Like he said.

BTW - "stick-stick" should have been "slip-stick". Where's that dang edit option?

Brian H | November 18, 2012

Timo said the Audi Forum has even crummier software than this one. I haven't bothered to check. {shudder}
