2007 swb brake issues after fluid flush
Thank you all for the pointers. I truly appreciate the help.
So i got to the shop and found out that he, in fact, did not perform the flush with techstream. He used the snap on alternative with manual bleeding for the front brakes and then the snap on tool bleeding for the rears. He only borrowed the techstream yesterday from a friend to run tests. I couldn't follow the recommended procedure because he had returned the techstream to his friend.
I'm towing it to a nearby dealership tomorrow for full diagnostics and bleeding for 480. Hopefully the problem goes away, but I'm prepared for the worst. I found 47070-50040 (pump assembly) for $850 and 04003-45450 (actuator) for a little over $1100. I know the dealership will likely refuse me bringing my own parts, even if they are genuine Lexus parts, so I will be calling around for quotes for the install tomorrow, just in case.
It's really difficult to communicate effectively with him because of his heavy accent, but it comes down to him insisting that the problem is just a coincidence and that he has done all he can. i really regret taking my car to his shop, but he is highly recommended within the clublexus southern California subforum. It's partly my fault for not asking about techstream explicitly. I'm also incredibly paranoid about my transmission now since i did a drain and fill with him the same day he did my brake flush.

Quick update: The car is currently being towed to Luxury Motorworks. I told Steve at LM to start with clearing the codes and bleeding the brakes. Hopefully that's all it takes. I also asked him to check my transmission fluid levels.
Big thank you to you all for the advice and support, and I'll definitely keep this thread updated as i learn more.

FYI... there were few others, including myself, that calibration process “broke” the actuator.
i think it puts a lot of pressure on it, and if it was on the last legs... well, you know..

GOOD NEWS ALL
Luxury Motorworks successfully cleared the codes and bled the brakes. The hardware is, as many of you suggested, working fine.
Thank you to everyone for the support through this whole mess! I truly appreciate all of you.

Glad to hear about the outcome. You must be relieved.
This revalidates the argument that the mechanics just start replacing parts when there is a problem doing trial and error instead of owning the mistakes. No wonder average Joe doesn't like cars out of warranty.

Couldn't agree more. Many dealers and indy shops tend to use the replacement of the brake actuator as an easy solution to LS460/LS600 brake problems, while some of the observed brake problems (dash lights, noisy, soft or non-responsive brakes, etc.) could have been fixed by a simple brake memory reset and re-calibration. Because the last step of replacing the brake actuator is the reset of the brake memory and re-calibration (the same process as a full brake bleeding/flush), these dealers and indy shops think that replacing the brake actuator solved the problem, while the reality is that the memory reset and recalibration fixed the problem. A simple preventative action for reducing the chance of having LS460/600 brake problems is to keep the brake fluid clean and bleed the brake system every three years by following Lexus LS460 brake bleeding procedure with Techstream.

I seriously don't understand how this guy earned his reputation with the socal members. Cool guy, but i didn't pay him to be a buddy. I'm gonna post up a thread about my experience as soon as i get some time. Totally unacceptable.
