How much brake fluid needed for flush?

It's been 2 years since I got my 550i. I-drive is reminding me it's time to change the brake fluid soon. I purchased the Motive power bleeder pump and catch cans. I have read that most users of this pump prefer to keep it clean by using it only as a pressure source and to just keep the reservoir full between line flushes. Sounds like the route I will take. How much fluid should I purchase to flush the whole system?

Just filling the reservoir and not filling the Motive is painful. Just get some denatured alcohol as Motive recommends to clean the tub out when you are done. Walmart has it cheap. Works fine to keep the Motive bleeder clean. I dump a liter of alcohol in the tub and pump up the bleeder and have it all come out the hose. Hang the bleeder upside down to dry out. All done.

Is there a reason to clean out residual fluid from the pump, other than just liking things clean? Would it otherwise cause damage?

Don't know, but cleaning it works out fine.

haha, that means you are good at it
at my first try on the E60 I went through 3 liters due to my inferior method of using a compressor and not able to see the fluid level

old fluid that was exposed to air is a big nono. Other than that, no contaminants!, because they can scratch the pistons.

Be on the safe side- buy 2 Liters and you're good to go.

I read that it takes exactly one but some ppl use 1 liter and a little bit more. Since I have 2 BMWs that requires the brake flush, I purchased 3 Liters.

OK, so I purchased 2 liters of Pentosin DOT4 LV brake fluid as recommended.

I used the Motive Power bleeder and their catch bottle and it worked great. I ended up using the method the instructions state by filling up the Motive container with the brake fluid and cleaning it with denatured alcohol afterwards.

My only concern is that the old fluid was still clean so I could not see a significant difference in color when the fluid was leaving the bleed valve and filling up the catch bottle.

I filled up the catch bottle about 1/2 way with old fluid from each location. After each location I emptied the bottle and bled some more fluid and what came out was as clean as the new going in.

I ended up using 1 1/2 liters of fluid to flush through all the lines and fill the reservoir.

My question for those who have used the Motive Power bleeder: How much of the catch bottle did you need to fill until the new fluid displaced the old at each location?

I really wish they still allowed brake fluid to be made in different colors. That would take the uncertainty out of the process.

Hearing that 1 liter should be enough to flush the whole system, I fell pretty confident that the old fluid was purged, but I would like to be put at ease.

Input?

You got it all. I've done flushes with the alternate colors and it only took .5-.7 L.

I like BMW brake fluid, usually for me, since I do it diligently every 2-yr, about 3 bottles (250ml each bottle).
I guess it'll be more if you have not done it in a while. I use clear plastic tube for drainage, once the color match the new fluid, it's good.

I have the same trouble seeing the fluid color change through the Motive supplied bottles. For one, changing the fluid in 2 years is going to not have as much color change as letting it sit for much longer. The other thing I did was buy a clear Nalgene Tritan Wide Mouth Water Bottle 32 oz. The graphics on the outside of the Nalgene bottle will come off with the brake fluid, but the plastic was fine with brake fluid. The same lid fits on this as the Motive catch bottles they sent me. It helps a little bit to see what's coming out.
