Brake Fluid inquiry

OK. I may be lost...

"Add fluid as I bleed"? I'll be putting more than a cup of fluid into that bleeder. Isn't that counter-productive. Doesn't that bleeder hold like one gallon????? That isn't reconciling with my limited sensibilities.

If I use the power bleeder dry I:

Suction out some brake fluid from the reservoir...

Add brake fluid to the reservoir...

Screw cap onto brake reservoir...

Pump bleeder...

Bleed a line until reservoir level decreases...

Remove cap from reservoir...

Refill reservoir with brake fluid...

Reinstall cap to reservoir...

Be certain pump is at correct pressure...

Bleed a line until reservoir level decreases...

Remove cap from reservoir...

Refill reservoir with brake fluid...

Reinstall cap to reservoir...

Be certain pump is at correct pressure...

Bleed a line until reservoir level decreases...

Remove cap from reservoir...

Refill reservoir with brake fluid...

Reinstall cap to reservoir...

Be certain pump is at correct pressure...

Bleed a line until reservoir level decreases...

Or:

Put brake fluid in bleeder...

Install cap to reservoir...

Pump to adequate pressure...

Start bleeding brakes until all are done...

Remove cap from reservoir...

Clean out bleeder...

Um... done.

What am I missing, seriously.

I find the alternative for which wholly the bleeder was designed to be incredibly inefficient.

If I'm missing something, tell me. I'll own it.

Thank you.

Pump to adequate pressure

I've done bleeding wet and dry and dry is by far the easiest and least messy. Do it correctly dry and you only have to refill the reservoir once. If you put fluid in the bleeder the after bleed clean up is more tedious than any other step in the process.

Basically you have the gist...

However...

Pumping up bleeder is not like inflating an air mattress by mouth - LOL. It's maybe 15-20 pumps (I dunno something like 20-30 seconds) max. Toddler water wings for the pool hold more air and at higher pressure - HA! If you're winded from pumping a power bleeder then please stay out of the driver's seat on public roads as you've got serious health issues and are putting other drivers at unnecessary risk.

When using a power bleeder dry I doubt you'll need to add fluid more than once to the reservoir for bleeding (maybe a slight top off at end to get to correct level - but usually I'm bleeding excess off at driver side corner to bring down to correct level). Maybe one or two pumps to bring pressure back up between corners but usually the whole axle can be done when starting at 18psi.

Good luck

It's a ****************ing bug sprayer with a pressure guage. Winded? WTF are you talking about?

I did take a look at the reservoir and I see what you're talking about. It's much larger than the reservoir on my Edge or bim. Thus, what you describe (top off) makes sense.

Who pumps up an air mattress with their mouth? It's 2019.

Thank you. Have a nice day.
