I'm not planning on being lazy. I'm going to do a flush every 6-9 months. Yeah dot 3 or 4 is fine. I went with dot 4 because our braking system is considered high performance. High performance braking systems likes dot 4.

 

As long as you flush regularly that's what is important . BTW all 2007 - 2017 LS's even F-sport say to use DOT 3 in both the owner and factory service manual .

 

I meant not lol.

Yes, i know the manuals state dot 3 but you can absolutely use dot 4 with no problem. Just because the manual says something you dont have to obey by it. Usually its a good thing to do but in this case i have found out our ls460 brake system is not your average braking systems. Technically the ls460 is consider high performance. I went with dot 4 but you guys don't have to.

Im loving how it brakes now after 2 full complete flushes.

 

Did you do the rest after the flush ?

 

The rest? I did all 4 calibers including taking out the old fluid from the master cylinder reservoir

 

sorry I meant the reset . linear valve offset reset . To allow the system to relearn new values.

 

Absolutely not!!!!! This is why so many members on here and elsewhere ran into major problems.. If i would have done that it would have been game over. Probably would had tow the car to the dealership.

There is so many miss information out there about bleeding the ls460 brake systems. You have to follow techstream to a T.

For just brake bleeding never do anything else like zero down, ecb, reset this reset that. You will end up losing pressure on your accumulator and actuator and then you're f.....

doesn't mean it cant be fixed but you better know the exact process to fix it in techstream. Like many others on here they end up towing the car to the dealers because getting everything back to normal on techstream is a complicated process.

 

After every flush , I do the following first reset memory then test mode then linear offset valve calibration. I have been doing this on my LS for the last 6 years. Doing this helps the system react better to your inputs . It's a little advanced procedure. Refer to your manual Section 5 .

 

Actually the manual is out dated. I saw somewhere lexus posted the updated version but you have to pay for it or work for lexus. They have since removed those instructions. It may have worked for you but it did not work for a lot of members.

The only time you do the zero down, ecb and reset is when you change either the actuator, accumulator, solenoids or the master cylinder pump.

Never do these procedures if you're just bleeding your brakes or flushing.

Follow techstream brake bleeding instructions to a T and you're good to go. At the end of the bleeding process techstream never instructed to do anything else. Just exit.

 

The only thing i am focusing on is the linear offset valve calibration its not only for actuator. In addition it also includes stroke sensor and stroke simulator solenoid. Also it fixes brake pedal sound . I have seen all 2007-2017 LS service manual new and old even non-US ones . Believe me it improves on the brake feel . But keep in mind it must be done right .

 

Let me see the instructions on doing it with screenshots if you can please. I probably won't do it since techstream did not ask to but maybe i might do it in the future after doing some deep research just to be sure.

does doing the reset and offset calibration require any bleeding process or unplugging anything?

 

linear offset valve calibration procedure does not require bleeding or unplugging . Here i have a video Its in arabic just follow the video . Car must be on a level ground and the steering wheel must be straight .

 

Did you follow the whole process on this video? Or did you just do the lineear Calibration?

 

Whole process . Like I said the car must be on a level ground with straight wheel .

 

omg i did and got check vcs bro and i cant delete it. I try doing it again same thing....f.....
