Answer
You should be able to pump fluid from the rear calipers.  All I can say without seeing the car it that your valve body under the hood is bad, or you are doing something wrong.

To find out if you're doing something wrong refer to the workshop manual, available at www.landrovertechinfo.com for a small fee if you don't have one, and do the steps carefully.

If it does not bleed there is also a procedure to check it further.  They do go bad sometimes and they are costly.
