If OP is flying EWR-BRU-EU and hoping for a 1h20 connection, I would not do this. Immigration is very hit or miss on this one.
But...
LED Is Russia, so this is non-Schengen to non-Schengen. OP would be fine with that connection if the flight's a normal time.
Alternatively, route EWR-IAD-BRU <even via SDC>, as that gets in 7:15 am - less international traffic in BRU then.
I've been decent on this route - haven't seen it too late, but it all depends on the day and other factors.
