DIY: How to Bleed Your Brake Fluid Using Motive Power Bleeder 0117 (AK370Z)

Just like the brake system itself. If you have fluid in the bottle, then you won't introduce air into the system.

I understand. Look at the video as the tank is pressurized the fluid began to go through the tube to the brake reservoir. However there is air ahead of the fluid that is being pushed into the reservoir. That is the air I am referring to. It is a closed system and that air has to go somewhere. Am I missing something?

that air that is getting pushed into the reservoir is depressurized when you remove the motive. the air does not get mix into the brake fluid.

I had the same concern. Apparently the fluid travels 'around' this air bubble. Perhaps someone with fluid dynamics background can better explain this phenomenon.

Brake fluid is heavier than air ... as long as the reservoir is not empty when you start pumping the bleeder, air will not enter the system because of the fluid at the bottom of the reservoir. Layman's understanding

That is true, but what keeps the air in the line between the tank and the reservoir from being pushed along with the fluid?

So how are u supposed to clean the motive bleeder with the denatured alcohol exactly? Dump some in shake it up and pump it through the tubing? Also do this before and after use? Let air dry after dumping out the alcohol before I put my brake fluid in for use? Simple questions but serious questions lol

I clean mine with denatured alcohol after use. Leave it open in the garage for a day or two to let what remains evaporate. Store it in a bag, in a box, ready for next use.

Well I'm workin on this right now but I cleaned my motive bleeder 4 days ago with denatured alcohol and when I started pressuring with after I put my fluid in there I noticed something floating in the line are you kidding me? I cleaned with the alcohol what is the deal? So what should I do now? it's just above my top finger there floating vertically what is the deal? Should I just continue?
