Question about flushing brakes
When i am flushing my brake fluid if i remove the abs pump resistor and any other abs resistors would that leave the a s system/pump open or closed while doing my brake flush.

not sure, but why would you bother with it? I don't know the design of the abs system on these cars but the amount of fluid in that system has to be trivial compared to total fluid no? i've flushed the LS many times over the years and never worried about it.

Just applying what I know from BMW, I would leave it alone.....BMW only recommends it when the ABS/DSC pump has been removed (which was my situation). They also recommend it when a caliper has been removed. But it requires a laptop/software to pulse the pump, or one of the newer handheld tools. The main purpose though is air, not fluid left behind. I took a closer look at the actual reservoir in the LS this weekend, and imho, I don't think the Lexus dealer did the turkey baster method on my car. I think what they likely did was to flush out one caliper only, rather than all four (imagine if I had a dash cam I wouldn't be speculating). The reservoir seems too tiny to effectively accomplish anything with a turkey baster...my .02

So best way I have found to do by yourself, is to go youtube and find the Gatorade bottle method. Basically the fill bottle has some fluid in it already so the system stays closed at the caliper end.
suction out the reservoir and top off then pump some out, top off and repeat on each corner (use best practices for the order to do each corner).
But easy/cheap to do and safe that you wont gulp air back in to the brake lines.

I am just wondering if you could flush the entire system then why wouldn't you yah know that was my logic behind the question. I have flushed brakes before i just never thought about the fluid in the actual abs pump, best way to clean it out would probably be to flush the brakes go drive the car engage the abs(slam on the brakes a couple times) then flush the system again...i feel that may be overkill haha

Flushing your brakes is of course good practice, but on the other hand, have you heard of many lexus brake master cylinders or wheel cylinders going bad? And how many regular joe's flush their brakes at all over a normal lifetime? a lot of people never do it, and yet the cylinders seem OK...ha, maybe we're just wasting money.

I don't believe this method is ideal, without pressurizing the system, it's pretty difficult to prevent air from being sucked back in, even if the tube is kept submerged...a Motive isn't that expensive, but you need the Toyota adapter since Motive doesn't seem to have one that's specific (I believe it has a chain to hold the adapter down and some say that doesn't work well)

as a matter of fact, this is exactly the method recommended for the LX470, which i've used a couple times. I believe the reason is that the LX has some sort of extra backup brake circuit tied into the ABS that holds some amount of fluid and the only way to flush it out is to slam on the brakes over gravel or ice, thus activating the ABS pump. I've not heard that suggestion relative to the LS however. Either we don't have that kind of brake system, or we're a different crowd than the guys over on IH8MUD.

If it's normal brake bleeding for flushing out the system or replacing a wheel-end part, there's no need to disable the ABS. Bleed as usual with the pump or pressure methods.

I bought a used Motive Bleeder last year and it came with the standard universal cap, which was held in with the chain. It's worked perfectly for me the 2 times I've had to use it. I just use it as an accumulator to hold pressure against the fluid in the reservoir. Not sure why others have had problems with the unit, but it's been great for me. Best 60 bucks I've spent on the brakes...

I bought this from Amazon https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
and it works flawlessly, it also fit ALL Toyota vehicles too.
