We derive general equations which determine the decomposition of the G+++ multiplet of brane charges into the sub-algebras that arise when the non-linearly realised G+++ theory is dimensionally reduced on a torus. We apply this to calculate the low level E8 multiplets of brane charges that arise when the E8+++, or E11, non-linearly realised theory is dimensionally reduced to three dimensions on an eight dimensional torus. We find precise agreement with the U-duality multiplet of brane charges previously calculated, thus providing a natural eleven dimensional origin for the "mysterious" brane charges found that do not occur as central charges in the supersymmetry algebra. We also discuss the brane charges in nine dimensions and how they arise from the IIA and IIB theories.
