Don't waste your time. "They all do that" really applies here.

What's up with the tude' here? :vader:
I have a feeling that in my instance, there's something else going on. The sponge noise isn't constant, seems to happen more after the vehicle has been driven for a few minutes. But it is loud enough that I've had passengers notice right away (who haven't driven in my LE before).
The sound is more of a woosh with a slight audible noise as I push the brake pedal in further just to clarify.

Everyone feels the have a "special" or "unique" issue or problem when they come here. Every now and then they are unique but not usually. I only copied a few of the links. Read them and see if you are special. As for the attitude, I posted a link to this thread first. I think that you are stating you are taking it to the shop when everyone tells you it's normal.

I have a feeling this one may just appear in someone's signature.:snacker:

heh. Well, I hope this isn't the norm as this is my first experience with a Toyota (other than my wife's Lexus).
The willingness in this thread to just accept the noise seems silly to me. It's rather embarrassing to have to explain to someone why my 2 year old car is making a noise every time I press the brake pedal in. Love the truck otherwise, but the noise is not acceptable to me right now.

I do not accept anything. The noise is part of the design of our brake system. Do me a favor: Go out on a deserted road, get going about 35 mph and just stomp on the brakes in a panic. You will not be bothered by the noise anymore.

1E, I have owned a wide range of vehicles before this one and I have never once encountered such a design flaw. There are other ways to design a braking system to respond to such condition as you've indicated above, without compromising interior acoustics.
Maybe the Toyota engineers had their ear plugs in when they were testing the 4Runner before production. I'm sure we could come up with a few more excuses if we put our heads together...anyway,
I hope that my situation is "special" and corrective action is taken...otherwise I'll be posting a few more annoying updates on this thread in the near future.

It's normal FOR this 4Runner. I no longer hear it, seriously...but I am sure it still does it ;-)

I am not singling you out per se it's just most people coming here think they are the only one having a problem or have a specific question. The truth is for something obvious like headlights, brakes, etc many people for years have been asking this same question.
Now on to brake system design:
I of course did not design the brake system for Toyota. I do not work for Toyota. I have however designed several braking systems for much larger machines so I understand the theory and practice of brake system design.
I will be the first to admit that the 4Runner's brake actuation mechanism is different than most passenger vehicles. What I have found with this design is the increased pedal travel is perfect for brake modulation when going slowly over uneven terrain. On highway, it works just fine for normal tasks and really shines in panic situations - once you know what to expect. The noise did take some getting used to but I truthfully do not even hear it now. For you to be "embarassed" and call it a "design flaw" says that you did not pay a lot of attention to it during your test drive and do not know how to explain it to alleviate the ignorance of brake systems to your passengers, hence giving you the links to further your education.
I am quite sure this braking system could be re-designed to eliminate the "swoosh" noise during brake pedal actuation. The question is what would have to be eliminated in order for that to happen. Again, I like the brakes on the 4Runner and the noise is not important. To others, it would I'm sure be a deal breaker.
I have included this link Engineering Inspiration - Brake System Design Calculations because it puts most brake design parameters in one location. The formulas are general in nature and not specific to brake design but this page shows how formulas are adapted to a specific application such as braking. Enjoy.

Ya I'm just used to it now. As long as it stops I'm ok. Also weren't there questions about how you have your foot on the brake pedal, but you needed to apply more pressure or the truck would move on you?

Above quoted is much more palatable than...
Though as you've stated, you weren't part of the design team that made the braking system on this truck.
Both of my test drives in my LE were done at the hottest part of the day (110 degrees ave highs here) with the air conditioning fans at max. I'll take fault on that, especially because I loved everything else on the truck and didn't pay much attention to testing some of the small details.
As for my embarrassment of having to explain the noise...I work in an industry which is less accepting of foreign made cars and trucks. Maybe I'm too picky, but I don't like having to make excuses for the braking system.
Side note: My wife loves riding and driving in the LE, but her first comment when she heard the brakes were, "The brakes on my (97 Chevrolet) Malibu back in college made the same noise."
I just recived an email from my dealer because I complained about the brake sound when Toyota called me for a survey. See bellow the email I recived from him:
hello,
I got a message from Toyota Canada about a noise you are hearing in you new 4Runner. You mention you brought it to the dealer and they told you its normal. Did you bring it to a salesperson , or the service department as I have no record of someone hearing it. I do have one of my advisors who drives a 2012 4runner, and I hear a sound from that area , but am not sure if that is what you hear. Shaun, my assistant said he had someone come in recently for this and concluded it was normal, but I have no way of knowing if that was you. I would be glad to listen to it if it wasn't. Let me know.

My dad's 2013 SR5 has been perplexing him for years with this squeak but I'm glad he's not the only experiencing this issue. Sorry we're late to the party lol
