screeching parking brake

Did some Googling tonight and it appears that Lexus has had a history of brake actuator problems. I'm not sure if this particular issue is similar to the issues they've had in previous vehicles. In the past, they've issued a warranty extension on certain (affected) Lexus vehicles.
Anyone else hearing this from their 2016-2020 Rx?

It's easily replicated for me - if I press down on the brake pedal and wait a few seconds, I hear what sounds like a metal ball dropping in a cylinder, which creates the clicking sound. It doesn't appear to cause any issues for me and I can confirm I don't experience a loss in braking of any sort, but since I'm out of warranty, I don't think I'll be doing anything about it as the actuator assembly is quite expensive.

I haven't had any issues with my brake actuator, but I've narrowed down a clicking sound I've been hearing after I press and hold the brake pedal to the actuator.

Be careful!

I have a 2017 RX 350. When shift from D to P, the automatic parking break will active. A robotic arm noise will occur (this is normal), but follow by a half second sharp loud noise.(not normal)
my Lexus dealer Put some lubrications on the related parts, but problem still exist.
Every time when activate the automatic parking break, After the robotic arm noise, the sharp loud noise is caused by break locking in.
The Lexus dealer say many RX has this problem and is normal, I think the dealer is just trying not to fix this problem. I checked many other cars e-parking break and has no problem. This sharp noise is very loud and not acceptable.
does Lexus dealer need to change some part in order to fix this problem?
does anyone has similar problem?
I appreciate if anyone has any suggestions for me. Many thanks

I do agree, the Lexus noise is a bit louder than other manufacturers but that's big a deal to me. Totally understand that some may be bothered. I use the sound as a notification for me to let go of the brake when I arrive at a destination lol.
