Hey RICHARD PACK,
There will be a banjo bolt securing the rear brake hose to the rear caliper.
You will simply need to undo the banjo bolt and remove the hose.
A picture below shows the rear caliper and hose.
I have also attached diagrams with the tightening torques for the hose and caliper bolts.
Hope this helps, let us know if you have any further questions.
Regards, Joe
