Mr Twister:

If you are still getting bubbles, then you have air either still trapped in the system... or being sucked in somewhere. 1st rule to bleed a hydraulic system, after bench bleeding the master cylinder (and did you bleed it properly?), the next step is to bleed the LONGEST brake line 1st... usually the right rear wheel. then 2nd longest... usually left rear. then right front and left front.

Were your "NEW" wheel cylinders actually NEW?... or rebuilt?... or NOS?

When I bleed brakes, I normally use a bleeder ball... it becomes a one person job, and if you have a leak - well, the system is pressurized so the leak will be clearly visible.
