  There are 88 stars which lack colours, but have measured parallaxes in
\textit{Gaia} EDR3 that place them within 20\,pc from the sun. Among them we
found two new common parallax and proper motion (CPPM) companions separated
from their primaries by about 3\,arcsec. The CPPM companion of a nearby
($d=14.98$\,pc) F1 star, \object{HD 105452 B}, was already imaged with the
\textit{Hubble Space Telescope} and is now confirmed with \textit{Gaia} data
and photometrically classified by us as M4 dwarf. The other CPPM companion,
\object{SCR J1214-2345 B} orbiting an M4.5 dwarf at $d=10.77$\,pc, represents
the faintest brown dwarf discovery made by \textit{Gaia} so far. It was also
imaged by the VISTA Hemisphere Survey and partly detected in the near-infrared.
Our photometric classification led to an uncertain spectal type of T1$\pm$3 and
needs to be confirmed by spectroscopic follow-up.
