Heath - Robinson would be proud.
I use about 10 psi air from my compressor. That pressure will depend on how well your H - R constructed cap seals. Also, check where your reservoir pushes into the MC housing. Its a rubber friction retention and if the rubber seals are tired it does not take too much air pressure for the reservoir to pop itself out of the MC launching brake fluid all over the place.
Watch the reservoir level like a hawk. The bleeding goes so quickly that you can empty the MC reservoir in a jiffy and fill your system up with air. I have a two part bleeder. It has a separate 1 l reservoir filled with brake fluid and that reservoir is pressurized forcing fluid into and also pressurizing the MC reservoir. Easy to check the external reservoir and refill it before the MC reservoir starts to drop. If I ever did empty both the external reservoir and MC reservoir before checking, serves me right for having to start the whole process over again.
