Does anyone have any idea how one might go about replacing a brake actuator on a 2008 LS 600hL? I bought the car a month ago, 200,000 miles, and was warned by the seller I might need to replace it. The dealer tech said the same thing last week. I bought a brand new Lexus actuator on eBay and I would love to save $755 (as I saw the labor listed on an invoice in another thread post. Thanks so much!!!

 

I would like to know the same thing.

 

It is the same procedure you would do on any hybrid cars. I just replaced it on my Prius. Just make sure you're really careful with all these hydraulic pipes. And after replacement, you need to use software to calibrate the brake system.

 

Any idea of what software I would need to calibrate the brakes?

 

techstream with MINI VCI J2534 TIS techstream Diagnostic Cable, OBD2 Scanner for Toyota Lexus Scion

 

Only the Japanese Estima in the 20th body has 9 elements the same as in the LS (there are 20 of them here). There are no more cars on such elements.

 

Thank you. I ordered it via link you provided. Much appreciated.

 

That's interesting to know. Is this fact changing my protocol in anyway? I am assuming it's not, and I have already ordered the MINI VCI J2534 TIS techstream. If it actually makes a difference, would you please let me know. And if you do happen to know which other techstream I would actually need, I would also appreciate the number/link to the correct one. Thanks in advance!

 

Here you go.
I used this tutorial when I replaced the actuator and motor assembly on my LS460. It has the 600h listed as well. I followed the steps as they were written.Technical Service Bulletin # SB0069-09

Brakes - Squawk Noise From The Brake Actuator

L-SB-0069-09

It is also the method for bleeding the brakes if they are making abnormal noises or air is in the system.. The guide is pretty straight forward. If I remember correctly It has you skip steps if your not replacing any parts. It's important to point out to follow the instructions and bleed them in the order as specified. You can't just pick which wheel to do first, second, third, ect. The computer only opens the specific port for each step. This is especially important for the rear brakes. You'll also need 2 people. I had my helper sit in the front seat. If you open and close the door it can mess up the process.
