The Annoying Sound All Our Tundras Make

We are all well aware of the clunk right after we start our tundras and drive off (both Tundras I've owned clunked).

This is not another post about trying to figure out why, we know why our trucks do it in relation to the ABS self test. I'm interested in knowing where the part is mounted, master cylinder, ABS actuator that actually makes the mechanical clunk we all hear.

For the mechanical guys, what component in the braking system actually makes the clunk?

If this part has been identified before other than "its the ABS self check" some input on its location would be helpful and or what the ABS actuator, pump, module does to create the clunk.

 

Toyota service literature calls it the "VSC Actuator Assembly". It's mounted just in front of the power brake booster/master cylinder on the driver-side inner fender. It's proximity to the driver may contribute to hearing the noise, but engineers chose the location based on function.

 

I have yet to hear this, since I bought my Tundra

 

Because you always have your Walkman blasting Queen when you’re driving.

 

Actually, I've never heard mine either, but I have heard it on other, high-end vehicles...not a clunk, more of a RRRRRRPP.

 

Yeah we haven't heard the "clunk" either....

 

Yeah, I've never heard this, even had Mrs turn on while I'm standing out side hood open, even walk with it while she pulls away from driveway and up to corner stop sign, never hear it

 

This post is worthless without VIDEO!

 

Home alone, Mrs left for work, kiddos left for work too

 

What? You need to write louder..

 

I'll search around for he VSC Actuator, for those that have never heard the clunk, thats great your truck doesn't do it. Both my Tundras clunk again its sporadic and not every time I drive away. Its odd that so many hear it and some just don't have it.

Yup, I've always wondered about that sound, thanks for the info.
