this way works excelent. i took a 1/2" piece of plate and welded an air fitting into it. i use a quick grip clamp to hold it on the resevior. i have done 3 or 4 cars since i made that thing and it works great. top off the fluid after you do the rear axle, then again after you do the front wheels. or you can top it off after each wheel.wedgie said:I took an extra master cylinder cap, drilled and tapped it for 1/8" NPT, screwed in an air fitting, and applied 5# of air from my compressor. Just go around and open the bleeders one at a time, until you have good flow, and you are all set. Just make sure that you keep the air pressure low, and keep the master cylinder full.
