There _may_ be a difference here between LHD and RHD.  On a RHD car,
the (unpressurised) feed line from the twee little reservoir enters
the master cylinder at 45 degrees to the vertical - i.e., the master
cylinder is canted over at 45 degrees.  Even pressure bleeding won't
clear the air out unless the whole length of the cylinder is swept
by the piston.
