    This is a gen 2 right there's a 19 page paper posted here of how to bleed the brakes without the computer it worked wonderful for me and I'll be using it on the Gen 2 from now on don't have to get any computers out and the brakes are working great. And that's good the prices were great worked out well you will find out you're taking a lot of the car apart to get these brake line snaked in there you'll have to bend them a little bit too I've looked at doing this on the Corolla and it was a pretty good size job so I imagine the way things are packed in the Prius which is predominantly a Corolla by nature it will be similar but once you get it in there it'll be done

    In replacing a brake line up to the actuator, there will be a chance of air entering the actuator. When that happens, the proper bleeding procedure is the longer one, of the two bleeding procedures available in Techstream. The car will operate the various valves inside the actuator in a specific sequence to make sure all the air gets out.

    Besides Techstream, some of the scan tools that mr_guy_mann reviewed in this thread here can also enter the brake bleed procedures.

    You will find various posts claiming you can do other stuff instead and your brakes will work great. Caveat emptor.

    With a 3rd gen, a couple of times now I’ve used a Kirkland mayo jar with a hole in the lid, together with clear tubing, with my mighty vac bleed bolt coupler pushed on. Put the car in invalid mode and went around the for corners in the order proscribed in repair manual: FR/FL/RL/RR. Had the car raised, wheels off and wife pushed brake pedal.

    Maybe take out a short subscription on Toyota Tech Info and get the non-Techstream brake bleed method. Attached is 3rd gen method, but the c might be different.

    see also brake fluid replacement link in my signature.

    Mendel has once again posted the non-Techstream brake fluid replacement method and called it a "brake bleed" method. It is not.

    When you are replacing, you start with an intact, undisturbed system already filled with fluid and no air, and you replace the fluid so no air gets in.

    When there is air, you have to bleed. When there is air in the actuator, the procedure for bleeding the actuator is what operates all the valves in there so you get the air out. In the manual, you will not find any non-Techstream procedure for that.

    Alright...after a long hiatus...i'm going to be replacing the dented fuel line, as well as Both rear brake lines. I bought all 3 lines from Toyota, along with a few of the clips (i'll probably break a few during the removal process)..... Total cost was around 350 for all the parts....

    Here is video of someone else doing the same thing:



    Its not overly complex but it is a pain removing all the clips and manuevering it all back into place (it runs the entire car length basically. Fuel tank may need to be dropped as well for the left rear brake line... I'm estimating 5-6 hours of total work...

    I'll keep everyone updated as i go through the process....

    Sounds about correct layout is similar in my 94 Corolla . A little more room in the Corolla but we're talking small imports here so that is moot Good luck and enjoy your project.

    Alright....both brake lines and fuel line have been replaced. Total cost of about 350 dollars. About 4-6 hours of time depending on how proficient you are working in a contorted position. Not super complex...just an overall pain to remove the clips and put everything in position...

    Does anyone have a tutorial on how to use techstream for the brake bleeding?

    Yes all of that posted here but you shouldn't need that you should be able to find the 14 page thing where you bleed without text stream or whichever makes you happy I did it without where you moved the relay or the one relay I didn't use tec stream and I have a perfect pedal I couldn't get tec stream to work

    Tombukt2 has been over and over posting about some "14 page thing" with a non-Techstream bleed procedure but never produced it or indicated where it came from, sometimes saying it's from the repair manual, but those of us who have the repair manual are still wondering where.

    The closest thing I know of in the repair manual is a non-Techstream fluid replacement procedure, but that is different from bleeding. In fluid replacement, there is no air in the system to start with, and that's why the non-Techstream procedure works for that job.

    I wish I could find that damn thing I thought Mendel posted it it's it was 14 pages long and it looks like it came out of the manual That's the same goofy pictures and page numbers I don't know what the hell happened to it All I did was print it out carry it to the car and threw it away when I was done it's the one where you take out the relay of course realize I'm working on a Gen 2. But I will be damned if I know what happened All I know is one set of axles you can bleed normally for the most part and then you take relay out and you do the backs or vice versa I'll find it somewhere because it was posted in a post where I was talking about bleeding the brakes on the Gen 2 when I was finishing up putting in my rebuilter used actuator which is only about 8 weeks ago at the most but I'll be danged if I can find it

    So i wasn't able to use techstream, and a regular brake bleed also did not suffice. I ended up taking it to the dealership. Used a 15% off coupon they had.....it cost 130 dollars and some change otd... Car is now whole!

    thanks to everyone for your help!

    If it was a thing Mendel posted, it was probably the fluid replacement procedure that he has posted before. There is a non-Techstream procedure for that, because for fluid replacement, there is no air in the system that needs to be bled out. We've been around that tree in many other threads.

    On the other hand, if you ever do find a non-Techstream actuator bleeding procedure in the manual, that would be something new under the sun.
