Motive power bleeder
May seem like a dumb question for some of you but I'd rather look dumb asking than look dumber causing problems.
One of my coworkers is letting me borrow his Motive power bleeder. His fitting is a screw type fitting so I ordered the GM fitting (1108). The time has come to bleed my brakes and... the 1108 fitting doesnt fit. Look at the Motive website and it says that I need the 1101 fitting. Ok, gotta order the new fitting.
While I am waiting for that, it occurred to me that there are two reservoirs. So, my dumb questions are:
The manual has two adapters (J29567 and J34098). Do I need both of these adapter as well as the Motive adapter? If I dont need the GM adapters, I am assuming I have to pressurize the front reservoir; however, what do I need to do to the other reservoir (ie: clamp it or will it be fine by itself)?
Thanks in advance.

Try posting or searching over in AutoX & RR.
Guys there tend to bleed their own brakes often enough
to be interested in products like the Motive unit. I have
seen them discussed.
Built mine based on a garden sprayer, adding a pressure
regulator and some other bits along the way. Buying the
Motive and its appropriate adapter would have been more
cost effective.

If you put a length of flex tubing onto the bleeder screw and the other end in a conatiner of brake fluid you can easliy bleed/flush your fluid w/o a helper.
Then you only need watch the fluid level in the reseroir driving the cylinder being bled.

The Motive is easy, fill the unit with your favorite brake fluid ( I use Valvoline). Fit the appropriate adapter to the master reservoir and pump the pressure up to about 8 to 10 lbs. Start at the right rear I think...

Another method is to keep the pressure bleeder dry and only add
fluid to the master cylinder.

- no need to drain & clean the bleeder tank & lines following the
current session (or prior to the next.) - less or no wastage of fluid.

Get a set of Speed Bleeders and avoid problems with pressure bleeding. They install in place of the bleed screw in each caliper and have a spring-loaded check ball that keeps air from entering the system once you open the screw.
Just give the screw a 1/4 to 1/2 turn and you can pump the brake pedal by yourself. No helper, no caps on the master cylinder reservoir.
Other posters say to not add fluid to the Motive pump; leave it empty and just pump it to build pressure. You still have to add fluid to the MC reservoir, but there won't be any fluid in the filler hose or a completely full MC reservoir so no cleaning up the drips or overflow.
