Brake noise on brand new truck

Is this normal? It's like an air or hissing sound. It wont let me upload the video. Only from pressing the brake a couple of inches. Parked, running on and off.

2018 TRd off road.

 

ROFL... I just came here to ask the same thing... yes, I have the same sound. Just like the sound of someone saying "Shhh". I haven't crawled under the dash to find the source yet. You are not alone.

 

Mine does it if I'm thinking it's the sound mine makes. 26k miles and no issues.

 

Dealer said it's normal? That all off roads and 4runners do it?

 

Its normal. Had it on my FJ, 4runner and Tacoma

 

Annoying as hell

 

What's it from??

 

Hydraulic Brake Booster?

 

my 2014 does it and so did my 2004 Tacoma and a 93 2wd hilux that I previously owned , not enough of a bother to worry about

 

vacuum assisted brakes

 

Quoted from the FJ forum " The noise you are hearing is the release of the pressurized brake fluid from the accumulator into the brake hydraulic system. If you open the hood, start the truck, stick your head back by the master cylinder/accumulator assenmbly and have an assistant push the brake pedal firmly, you will hear it even more clearly. More importantly, you will hear it coming from the accunulator as I describe."

 

So nothing to worry about?

 

Nope

 

Why doesn't the sport model do it?

 

Not hydraulically boosted like the FJ, 4runner, and OR Tacomas

 

So does off road have better brakes then? And do they all do it? I dont see a lot of people posting about it. Or does just some OR make the sound?

 

Wondering if I should have kept the sport and not swapped for the off road

 

I don't know about "better" on the street, but the fact that Off Roads and Pros have Crawl Control/MTS or ATRAC (Manual Trans) would be the primary reason for the electric/hydraulic brake booster.

My '16 makes that sound, you can hear it clearly with key on/engine off and pressing the pedal.

Normal.

 

Why?

Unless you're thinking about more expensive and complex repairs down the road...

I guess I don't even notice it any more..

 

Turn up the juke box and get over it.

It may be Toyota engineered and built, but it isn't a Lexus. It's a truck.

This was a 'feature' even on 2nd gen ORs. It's not a 3rd gen issue. Or any issue at all.
