I never cared for the power bleeding systems. If you have a leak it makes them a bigger one, and a mess to clean up. Although it would be nice wiuth the small master chevy provided for the big trucks and to use when you have a hydro-vac in the system. We just let gravity do most of the work. We didnt mind the 2 guy thing, but it is hard on the thread of the master having to refill it all the time.
