Hi guys,
Simple stupid question:
http://store.motiveproducts.com/euro...-0100-p34.aspx
That's the one I should be getting, right?
Also, any recommendations for the brake fluid itself?
Thank You!

Yup, that's the one I use also. As for brake fluid, I prefer ATE Super Blue or Gold.

Sean (and others who are longer-term regular users) --
I took some time to fit a nylon hose in place of the vinyl connector hose. On my home-brew version, I'd been using a reinforced hose for all but a short connecting stub of the original stuff, but that short piece was pretty crispy. For others who have this Motiv unit, pay particular attention to the condition of the plastic hose. Over time, brake fluid seems to leach the plasticiser from the normally-flexible hose. It gets stiffer and is subject to fracture with nasty consequences possible.
My replacement hose is a short section of 1/4" self-recoiling hose. I tapped the bottle nozzle with a 1/4-NPTF, and threaded the hose connector in there with an o-ring and with teflon thread tape. Found some AR quick-disconnect fittings too, so these will never be confused with common air hose connections accidentally.
Now, back to your regularly-scheduled thread discussion...

First time I used mine, when removing the cap from the reservoir, I managed to pull one nipple of the reservoir out of its m/cyl grommet, and spill a bunch of fluid . Eventually found the basic problem was the grommets had swelled over time (only 6-7 years since last replaced), and werent fitting properly.
So take care with loads on the reservoir. Apart from that, it works fine.

Bob, wouldlove to see a pic of what you did. I have wondered about putting a swivel fitting on mine. I got it out last week for the 1st time since last fall and the hose had crimped almost closed in the middle. I gotta do something before next use.

Test it under pressure before you get it near your car especially as it ages.

Many folks feel that, because the gauge on the Motive goes high, it needs to be pumped up high. I've found that "just enough" to get the fluid flowing is really enough. Somewhere south of 10 PSI is plenty. It reduces the risk of surprises. Also, normal safety measures include taping plastic (I use handy garbage bags) over the fenders, and stuffing a large towel under and around the MC itself to catch anything that might dribble. The MC reservoir cap I modified has about half an inch of fitting protrusion into the reservoir. When I de-pressurize the bottle when finished, it draws that little bit of fluid back through the hose. The quick-disconnect fitting seals the hose on removal from the cap so minimum dribble possible there. It also acts as a swivel connector, answering chrly924s' question/comment.

So the big red lettering "Brake Fluid Only" wasn't a good enough hint? (???!!!)

For those playing at home, if you happen to have one of these coily air hoses handy, try blowing through it. There's a pretty impressive amount of flow resistance stored up in the coils. Not saying that a similar but larger-piped version might not be OK for filling the transmission, but it would take a bit of pumping and pushing to get ATF to flow through that baby-diameter hose at any significant rate.

I have used the Motive and like the features of this one better.

Have the Motive power bleeder for many years now and its been used many many times for brakes and clutch bleeding. Never had an issue but did add a short piece of tubing to the cap so when finished bleeding and the pressure is relieved the fluid in the MC is sucked back into the bottle leaving the correct max level.
