One thing to consider relative to the instructions for the Motive unit. Some users are not putting the new brake fluid into the pressurizer, they just put it in the brake res. The advantages of this are that you do not have to clean the pressurizer and you have less chance of making a mess. The disadvantage is you have to check the res and should expect to have to take the pressurizer cap off to add more fluid at least once before you are done. It still seems like a better process to me. If you forget to check and force air in the lines, however, it would be a very big minus.

Our bimmers will take a threaded cap so installation should be fairly straight-forward (although I appreciate the comment on the black label metal adapter maybe requiring a different o-ring). If you have to go to the "universal" cap arrangement which clamps in place (apparently required for my Suzuki SUV), I'm not sure these units would be better than just recruiting an assitantant and doing it the old fashioned way (one person pumping brakes, one person opening bleeder as the pedal is depressed but closing it before each upward motion of the pedal). The reports I've read indicate the clamping arrangement is a bit difficult to get to seal.
