My car also has the Jag rear and, when the car was new, the emergency brake squeaked intermittently just as you described. If I pulled up the brake handle just a little the squeak would stop, so that confirmed it was the pads. I wanted to avoid tearing into the rear if I could so I tried making a number of stops using the emergency brake, not overdoing it so as to overheat or glaze the pads. That worked. The squeak did return after a while and the same process stopped it again. After a few cycles of this it never came back.
