In Rave the internal switch is supposed to be removable. I don't know if it is a separately purchasable item. I recently replaced my whole reservoir which solved a whole raft of issues.:)

In RAVE, the brake fluid level switch (X111) is connected to the BeCM on connector C1289 on pin 16. I'd be checking to ensure that that connector (or connector port) is getting a solid contact. Maybe the switch is fine?
On the Becm, it is the connector on the front, on the lower row, second closest to the drivers door.
