Differential vent

My friend had new brakes installed on his 56 Patrician.The mechanic checked the fluid in the differential.He said there was a quite of bit of pressure built up when he removed the cap so he suggested my friend clean the vent.Was under the car saturday and could not locate it.Does anyone know where it is?
