I recently replaced all rear brake hardware on an 82 vanagon from the
control valve all the way back to the rear brake cylinders; all brake
lines, unions, connetions, and both rear cylinders, thus my job was way
more severe than yours.  All I did was bleed the rear half of the brake
system.  I did not need to bleed the front system at all and everthing
is ok.
