Brake booster hum (1 Viewer)

[Sinister]

Anyone else find this mildly annoying? In stop and go traffic, if I have the radio low or off every time I let off the brake and then re-apply I can hear the hummmmm. Is this normal for the LX600? Anyone else notice this?

Yes. My 570 does it too FWIW.

Yes. My 570 does it too FWIW.

I don’t recall hearing it all the time with my LC200.

I hear it occasionally on my 200.

Oh yes, this is a legacy issue from the LC200 that was overlooked in the new generation.

uh. this is one of my biggest annoyances. There is a hydraulic booster noise that is carried over from the LX570. It happens with the same cadence and frequency as the 570, not too irritating.
There is also ANOTHER booster noise, happening VERY FREQUENTLY, this is the electric brake booster I was told, and every new toyota with the safety features of 2020+ has this annoying higher pitch booster noise.
