Getting my wife to help bleed is sometimes like pulling teeth. I recently tried the mittyvac system which pulls from the caliper, but it pulls in air so I don't really like it (good at pulling new fluid through, but impossible to tell when no more air is in the system). I'm now considering the motive kit, but before wasting money on it I'd like to know what you guys think. What's worked best for you?
I have the Motive kit and it works great. I had been using just a catch bottle and pumping the pedal by hand by myself. The first time I used a Motive bleeder, I thought to myself, "That's it? That's all you have to do?"
I wish I had bought it years ago.
TrackHQ.com sponsors should be your first choice when purchasing.
Motive Miata Power Bleeder
I just use the Motive reservoir cap, attached to my compressor at 5-10 PSI. Fill reservoir, apply pressure, bleed away.
I have the Motive bleeder and Miata specific caps for the Miata (brake and clutch res). Works fine, but you have to use low pressure or you will pop the reservoirs off the cylinders. On the BMWs, 14psi was no big deal, on the Miata, it lifted the reservoir at ~10psi. I believe if you used the universal cap, with chain under the cylinder, it would work better.
Before anyone asks, the motive cap for the clutch is 1100, same as the older VWs.
I routinely use 15-20 psi on the Miata with no issues. I am using the billet aluminum cap and not the plastic version of the cap though.

I am afraid this a dumb question, but here goes: with the motive power bleeder, do you really need to put brake fluid in the bottle, or can you just pump it up so you can bleed a few bubbles out at the calipers? The Instructions say you need to put brake fluid in the bottle, but unless you are flushing the whole system it is a PITA. Seems like it would be fine to just use the empty pump to create some pressure, then top off the reservoir afterword if necessary.

I use the Motive bleeder and skip on putting the fluid in the bottle. I just watch the MC level and refill everytime it gets low. Takes a bit longer, but has less mess and I only use as much as I need, no more.
At the track I use the Motiv bleeder (no fluid in the reservoir). In the shop I use the shop air to pressurize the the Motiv cap. The Motiv cap whip has a digital paint gun regulator and an inline drier. There is lots of moisture in compressed air typically and you don't want the moist air contaminating the brake fluid. It takes minutes to bleed the brakes with this setup.

Maybe your gauge is off? I have gone as high as 25 psi (1111 adapter) both with compressor air supply and the Motiv pump without issues.
I have a Motive Bleeder w/o the cap that I will give you if you pay shipping or I will be at Buttonwillow April 23-24.
Send me a pm if you are interested
I pump the brakes, walk over, and close the valve. Seems to work.
Mark, I have both.
I have also had reservoir lift issues on my Acura using the Motive. Neither the e36 or e30 flinched when I used it, I expect the same trouble free use on the e46. It seems each Japanese car I have used it on blew fluid/lifted the reservoirs.
I'm also like the people above who use a motive cap and hose and pressurize my reservoir with about 10lbs of nitrogen when trackside. Otherwise I get wife to help. Trying not to make a mess I cut an "X" in the top of a water bottle cap and screw the cap and hose into an old water bottle to collect the bleed out.
