a cheap and available material to do this is a section of a rubber vacuum hose about two inches long, slit about 1/4 inch with a razor blade in the middle. one end plugged, the other end slipped onto the bleeder screw head. pressure from the brake master cylinder pushes the air out of the slit, upon return of the master cylinder, the slit rubber hose partially closes enough not to allow air from getting sucked into the brake cakiper or wheel cylinder.

i have used this for years, the surface tension of the brake fluid on the threads makes it partially airtight and the speed of the master cylinder piston return is way much faster than the tendency of the air to reenter the lines. or you can drill one sacrificial bleeder screw straight down from the outlet end, when the bleeding procedure with pedal pressure is done, continue with the gravitational bleeding and then you reisntall the unmodified bleeder screwLast edited by jick.cejoco; February 5th, 2010 at 06:01 PM.

in an automotive shop, brake or clutch hydraulic system is done by one person operation using pressure bleeding procedure, vacuum bleeding procedure or gravitational bleeding procedure, the ts is asking where he can purchase a "special" bleeder screw. there are some available but hard to find tools of this kind. the rubber hose used like a reed valve eliminates the other person of the two man bleeding procedure and is readily available. yes, safety is paramount, as long as proper procedure is used on reassembly and bleeding the hydraulics, it is safe and routine for professionals or personnel who have been doing this procedure.

February 5th, 2010 11:14 PM #8thanks for the replies. the hose thing sounds interesting and i will give it a try. but just to make sure, i'll have somebody around to help bleed the system before i tighten the screw. you never know when you will find yourself in one of those mcgyver situations.
