I just finished cleaning out clutch master cylinder and slave cylinder along with a good flush of the line. I read were many folks were having a hard time bleeding the system after working on it mostly due to the long length of line. Something I learned in the Army for something like this long line bleed was to fill's the line before hand with the fluid before bleeding. this fill the void in the line of fluid not air. In this case I just removed the banjo line on the master had a cup of clean brake fluid asked my charming assistant (my wife) to hold the fitting submerged in the cup of fluid (wear gloves) while I connected my hand vacuum bleeder to the slave bleeder (1982 V45) and proceed to draw in the fluid from the cup to fill the line. Once the line was full (the vacuum pump started showing fluid) I close the fitting on the slave put my finger over the hole were the banjo fitting goes and a few pulls on the handle to draw the fluid into the master then reconnect the banjo fitting on the master and proceeded to finish the bleeding all within five minutes. If all else fails give this a try.
Stay Balanced ;-)
I bleed mine from the bottom. Bubbles want to travel up the line, so why not let them? Open the master reservoir, fit a plastic tube or hose over the bleed zerk at the bottom, and pump fluid up from the bottom with a pump type oil can filled with brake fluid. Watch the reservoir at the top. When it quits bubbling, close the bleed zerk, remove the hose, and, if necessary, remove excess fluid from the reservoir to the correct level.
Learned to do this bleeding brakes on a light aircraft, with a similar height difference between the master and slave cylinders.
Both good ideas. I will have to try this some time.
