On bleeding brake lines without help. Get a rubber hose that will be a tight fit on the bleed
valve and long enough to reach into a coke bottle
sitting on the floor nearly to the bottom of the
bottle. Fill the bottle about a third full of fluid and fill the master cylinder. With the
bleeder valve loose at that wheel, slowly pump
the brake pedal. The fluid will fill the lines,
the air will go out the end of the line in the
bottle and the fluid in the bottle won't allow
air to suck back in the line because the line will
be in the fluid and will suck in fluid. About
every three pumps, check the master cylinder and
the bottle to be sure it isn't over-flowing or
being sucked dry. You'll get the hang to it after
a while. Do each wheel, starting with the farther
-est from the master cylinder.
