What is the Best "Low Cost" scan tool that can bleed brakes?

Autel is responsive to emails, iirc. I'd reach out to them and ask.

Is this for engaging the ABS circuits during fluid flushes?

 

The best part may be no part.
Friend of the forum @NutzAboutBolts has vids about this for G3's IIRC (???)
I might be misremembering that and the G5 brakes might be VERY different.

Still.....some of these videos might contain....DO contain useful information.

Good Luck!

 

You don't need a scan tool to bleed brakes or replace brake fluid. Just follow the sections labeled "When not using Techstream/GTS".

 

^ See the 5th gen (last attachment) is the usual order: start with front/right corner, go around counterclockwise. Toyota manages to spell this out in an absurdly obtuse manner, as always.

Video 18 here is good:

they used a vacuum device. Not really needed. Some tips here:

This is not the first post on PriusChat to have mixed up brake bleeding and brake fluid replacement, which are different procedures.

From the first attachment in that exact post:



That means exactly what it says.

From the second attachment in that post:



The brake fluid replacement procedure is the only one that has both a Techstream and a "When not using Techstream" procedure.

You are doing brake fluid replacement if all the following are true:

• The system is already full of fluid and completely bled.
• You are adding new fluid at the reservoir and letting old fluid out at the bleeders.
• You are absolutely careful to let no air be sucked in anywhere.

If that is what you're doing, you can use the non-scantool fluid replacement procedure.

It may still be prudent to have on hand Techstream or another scan tool that can do brake bleeding, just in case any air is allowed in the system during your fluid replacement. Because if that happens, you are not doing fluid replacement anymore, but brake bleeding.

 

Okay, then let's say that the non-GTS instructions work just fine if you're doing standard brake maintenance(calipers and flex lines) and traditional brake bleeding(the lines, not the ABS actuator). If you're doing big things like replacing major system components like the ABS actuator, you ran the reservoir dry, or you think you had a leak somewhere for a long time, then you need to use a scantool in order to fully bleed the actuator in addition to the lines.

Does that sound about right?

 

Pretty much. If you've only done work out at the ends of the lines and a small amount of air got in only there, you have ok chances of getting away with a non-scantool procedure.
