The slave up bleeding concept is nice but keep in mind it doesn't work so well across all applications. Some cylinders and bleeders are very restrictive and the ability to induce fluid into a line under pressure from an oil can pump mechanism is often extremely difficult. The amount of pumping to overcome pressure in the cylinder and lines can be more than the oil can can overcome. Worst yet is that the bleeders are usually far too short and do not allow the bleeder line to say in place. As an engineer, I have NEVER understood why bleeders are not 2x longer with multiple barbs to hold bleeding lines in position without fear of them popping off and allowing more air back into the lines (or pressurized fluid from running out). As usual, each application may and often does require different methods.
