Braking

I was very concert, because I just bought a brand new Tacoma.

 

I wonder why does it do that?

 

Hopefully I'll get us to it.

 

It is not an issue. You have an electric brake booster that you are hearing, which is normal considering how quiet this truck is.

 

Oh ok!!! Thanks 75z28!!! Do u know this applies only on the 2018 Tacoma off road? Or on only certain Tacos? Since this truck is brand new. Might have to wait for the engine to break in so I won't notice the electric brake booster is going off. Lol jk

 

It is all offroad tacomas--not sure about manual transmission though.

You'll always hear it. Mine is there, but you get used to it.

My camaro has hydroboost on it and makes the same weird noises.

 

Thank you sooo much again 75z28! I was about to go to the dealership and raise hell!!! Lol

 

Uh what? I don't have a noise when braking.....

 

It's has to do with the AT models.

 

I have an AT.

 

Off Road and Pro's use a different stye Brake Booster to control Crawl Control and or A-Trac systems, the pedal in my truck does not make noise.

 

I have no idea then. Have you had the brakes serviced since you bought it. Mine sounds like the caliper pistons are sliding to fast and hit the rotor with a clank. It usually happens at the first touch of the brakes after moving.

 

That's what I thought I remember reading but don't want to give out false info. I have the sr5

 

The only time I have sound is when it first starts up and I can hear the booster kicking on, kind of whining sound and you can feel it in the pedal. Only other time is when traction control kicks in for some reason. Otherwise it's silent.

 

Right, you have a traditional style vacuum booster, those can make a very brief hiss when you first step on it.

 

Hahaha, there is no hiss that I can hear just a "clank" from what seems like passenger front wheel.

 

It is very faint, you literally have be listening for it, or sitting at idle in a drive way next to a wall to hear it.
Mine has always made the noise. Usually if you have your blower on for the fans/ac you won't hear it.

 

I wonder if that's only on the 2018 Tacomas Off Road?

 

Nope, even some of the 2nd gens used the same booster.
They shouldn't be super loud---it will have a sound even though some will say it doesn't. It is literally just the nature of what is happening.

 

75z28 u know what I'm talking about. Thanks
