Modifying the use of my Motive pressure bleeder?

efhughes3 · efhughes3's Garage

These work very well at bleeding and flushing. But, I get concerned about how clean it is over time. I'm thinking of going to use this only to pressuruze the system and not intorduce new fluid also.

Any tricks to this?

I'm assuming you remove the interior pickup tube?

I'm aware that I'll need to keep an eye on the fluid in the M/C so as not to introduce air into the system that way.

I always flush the power bleeder before I start. Put a couple ounces of fluid in the tank and pump it out. Throw this fluid away. Refill the bleeder and continue as usual.

Just leave the resevoir empty, and you will only pressurize the system. No need to modify.

I use it as a pressure vessel only. No modification necessary. Haven't pumped any air into the MC yet. Yes, it takes a little more work, but I always just preferred the thing clean.

You can clean the bleeder out with denaturalized alcohol and then let it dry. It will be as clean as new. Do not use anything like brake parts cleaner or other solvents that potentially harm the plastic.

The problem with bleeding with a dry bleeder and only going with what's in the reservoir? If you run out of fluid, you'll pump air into your mc and brake system from the top. That's going to be hell ... You may think the risk is small, that you do this, but the consequences if you mess up are pretty bad IMHO.

Pressure only. I use and sell these - and they are a mess to use with fluid inside, IMHO

I've done that (blown air through the brake system) so many times it's not funny. I've never had a problem "fixing" this. I just put more fluid in the reservior and pressure bleed it again.

I only have a ho-made pressure bleeder consisting of a used master cylinder cap from a junkyard VW with an air chuck connector screwed into the top. A couple of years ago I "got fancy" and added a dedicated regulator and some of that lightweight self coiling hose.

Nice thing with runing a Motiv dry is just release pressure on the empty bleeder, unscrew, and add more fluid - easy to bloop more in the m/c reservoir. Bake for 5 min and watch closely!

I wholeheartedly agree with Craig...dry is the way to go. Although I've never 'messed up', and added air to the system...it's no big deal if you should do that imo.

Many thanks for the responses-dry it is....

If you are starting with a new Motive unit and you are only adding new brake fluid each time you use it why would it ever get dirty?Am I missing something here?When I'm done useing mine I empty out any fluid in it,close the top down and put a plastic sandwich bag over the end that screws onto the master cylinder,I think I'm keeping everything clean,am I wrong?

Attracts moisture in a BIG way -

Also the Motiv hose gets soft over time with the fluid residue in the tube
