Very informative and worrisome. It would explain why so many units require replacement. Lexus procedure doesn't produce a proper flush. Am I reading that right? Seeing those particles of debris with your own eyes convinces me that finding an independent shop who will comply with your procedure is my best bet. If not, is your procedure something I can do alone? No one to press the pedal for me. Would a vacuum type bleeder do the trick?
You can't really do this alone easily, a vaccum type would work but the front bleed according to the TS procedure would need you to pump it and place a rod between the chair and pedal. Then you would go outside the car and open the required bleeder, close it, return inside and continue on. Use a soft ended rod with lots of padding to prevent damage to anything....
You will need techstream or something equivalent to perform repeated zero downs, I have not yet come up with a way to do this without it. I'm trying to see if I can figure out a way via the wiring diagrams to short out pins to open the valves.
It's not easy though since unpowered is closed
Thank you very much for your response. I think it'd be more of a certainty to get it done right as DIY like you stated. Getting Techstream and finding a neighbor isn't impossible for me, I just need to make it happen.
