I am having a heck of a time trying to get the front brake to work on my recently acquired 1981 650. There is no pressure when the break lever is retracted. I tied to bleed the brakes as described in several threads on this forum but to no avail. No air bubbles or movement of any sort in the resovior. I remove the banjo bolt at the lever and was able to pump fluid through the line. I also pumped fluid up to the upper banjo bolt through the bleeder valve on the brake caliper.
With the upper banjo bolt removed I can develop some pressure if I fill the area where the banjo bolt goes with fluid. If I don't manually fill the space I cannot get but a small amount of fluid to discharge when I pump the lever. Any thought on this subject? Is there any way to verify if the master cylinder is actually working as intented? Is there any such thing as gravity bleeding? Do I need to bleed the master cylinder?
