I do, but it's for when I flushed the brake fluid in my Porsche and not my wife's Lexus. I still need to buy the Toyota/Lexus adapter for my Motive Power bleeder in order to do my wife's car. I need to get that ordered soon as it's probably due.

Motive has a universal round one but I have read that sometimes it doesn't work as good and it can't hold pressure.

Below is what I received from Motive. Looks like I will be using my Mightyvac to flush the brake fluid out.
"Hello,
Most toyotas and Lexus use a reservoir cap that is just pressed or snapped onto the reservoir. As such there is no way to secure a cap onto the reservoir easily for use with a pressure bleeder. You need to use a kit that is secured or clamped to the reservoir by some other method. Our kit uses a set of chains and j-hooks to secure the adapter. One thing to watch for tho is if the reservoir is jammed up under the cowl - if it is there may not be enough room to use the adapter.
Both kits 0101(includes adapter 1101) and 0119 (includes adapter 1119) use this method.
The caps for both kits use a chain that runs under the master cylinder and then hooks up to the cap and is tightened with wingnuts. But many customers have found using some shop clamps works well. See this blog post

OK I just checked the repair manual and the TechStream tool is only needed to bleed air from the master cylinder or actuator. If you are only replacing fluid you can use the pedal pump method or pressure method. Just never let the fluid get below minimum or you may allow air to get into the master cylinder and you're hosed!!!

No problem! I won't buy the Motive adapter as I have a mityvac, which is also a useful tool for bleeding brakes. I might do a video on how to use the mityvac to bleed brakes, will see.

I would like to add to this thread that I have both the Speedibleed and the Motive pressure bleeder.
Using the Speedibleed is much cleaner and quicker for Toyota cars.
The Motive pressure bleeder requires one to wrap a chain around the brake fluid reservoir cap and master cylinder. I've had it leak due to it being misaligned or not on tight enough which causes a huge mess in the engine bay/floor.
The Speedibleed is a cap with a thick rubber seal inside and uses wingnuts to secure on the brake fluid reservoir. The Speedibleed includes a pressure gauge which is much higher quality and accurate than the Motive one.
Not trying to sell anyone on the Speedibleed, only stating what my experience has been after owning both. Both do a good job if setup correctly, but given how Toyota's don't have a "screw cap" design for the brake fluid reservoir, the Speedibleed is cleaner and quicker.
