  For a symmetric pair $(G,H)$ of reductive groups we extend to a large class
of generalized principal series representations our previous construction of
meromorphic families of symmetry breaking operators. These operators intertwine
between a possibly vector-valued principal series of $G$ and one for $H$ and
are given explicitly in terms of their integral kernels. As an application we
give a complete classification of symmetry breaking operators from spinors on a
Euclidean space to spinors on a hyperplane, intertwining for a double cover of
the conformal group of the hyperplane.
