Anyone know why the 95s are prone to do this? Perhaps the cooling

Maybe the smell is the heat from the resistor grids being dissipated
when using rheostatic braking? I don't know if the Northern line can
accept regenerative braking. (i.e sending the energy collected back
to the supply source)

I would suspect the smell is from friction braking when regen/rheo braking
isn't able to be used?

Its definately not a brakes smell, its a distinctive hot metal burning smell.
Hot brakes smell completely different. It could be the resistor grids I suppose
but it seems to occur even when the train hasn't been going very fast before
the station. Whatever it is, its a bit disconcerting as a passenger.
