One person - fill a container with brake fluid, push a length of clear
tubing onto bleed fitting, insert the other end into the fluid container,
open bleed fitting, pump the brakes as if two people were doing it. Air out
into container and nothing but fluid back in.

We do it that way on airplanes BUT......The bleeder is mounted on the bottom and the brake line is mounted on the top of the caliper / cylinder. On an automotive application the bleeder and brake line are reversed so you can not get all of the air out if you pump it backwards.

Wouldn't you get all but the air between the cylinder and the bleeder? One pump of the pedal and you should be done after bleeding backwards, no?

On a car or a motorhome I would assume after you force all of the air out by pumping it backwards from the wheel cylinder to the master cylinder that you could pump it forward and get the remaining trapped air in the wheel cylinder to come out of the bleeder. I have never tried this. I always go forward from the master cylinder to wheels cylinder on cars. I always go the opposite direction on aircraft systems because that is the way they were designed.
I have found that my GMC will gravity bleed very nicely. I can take a short piece of clear hose and attach it to the bleeder. The stick one end of the hose in a small bottle and open the bleeder. You can watch the air come out through the clear hose and into the bottle.
This just another way of many to do it.
I have pressure bled them, pumped the pedal, gravity bled them, and used a vacuum bleeder attached to each cylinder. All seem to work. I do not have a favorite way to get it done.

i've done that too with limited success. the biggest problem i had was getting the air out of that vertical loop above the combination valve.

I too had problems.
Fred, how did you know the air was/is stuck near the
combination valve?

I have HER pump the brake pedal while I crack the bleeder.
Three pumps then hold, then I crack the bleeder. we repeat this three times. Usually works just fine.
I have a friend who uses a thing he attaches to the MC and an air hose. Not sure how well that works without someone at the brake pedal???

I have one of those I made. It works great. I loaned it to another GMCer last fall. I probably should call him and get it back.

Ken,
If you ever get it back, I would like to borrow it if possible. I have replaced all brake lines and am currently looking at the Speedi-Bleeder K300, $139.00. I saw another post on here way back with good results. Can't find the post again. I hate to pay that much money for a tool I only need once.

Send me an off net email with your address and I'll email the GMCer who has it and ask him to send it to you.

it's only a guess but i pressure bled from the master cyl. and could not get any more air out. it was suggested to me that the combo valve could be the problem. the fluid can pass under the air bubble without moving it down the line. i cannot see how gravity bleeding would eliminate it either.
my problem started with me replacing everything at once so the system was empty; lots of air in there. it took a LONG time to get the brake light to stop coming on.

Hi All..
Well in search for better brakes.. I am in process of replacing all of my brake lines with new Stainless lines from Jim K. They are pretty but expensive.. So far I have replaced them all but the one that runs from side to side in the rear.. Had to give it a break due to the foot of snow we got here last night and so far today! So far I haven't seen anything that should have given me me problems.. BTW I am also replacing the master cylinder with a new (Rebuilt) one.. I have tried 2 other new ones from Jim K with no improvement so what the hay!
I will start the bleeding process with a gravity bleed.. I have a power bleeder and will also give that a final shot to be sure I have got all the air..
I have discovered a new problem however... I noted what I felt was a bad wheel earing on one of the rears.. Kind of surprised me as I had done a repack and reline of all rears a season ago.. When I pulled that drum I found that the lining was down to the rivets.. Really shocked me.. Not only do I have Shit brakes but they are wearing the rears at an alarming rate.. The fronts appear OK.. I also installed an new Prop valve a couple of years back (Jim K) so I am at a loss to figure that out..
I ordered new rear shoes and all hardware again from Jim K so I will replace all of that again to see what results I have this time with all that new stuff again.. I am hoping to have this all done within the next week so we can take our maiden voyage this season to Arizona and points south west!
Let me know what you all think!
Ron
