Didn't this happen to Jays - on the newer cars with self adjusting rear brakes this is a real pain to replace. Interior out job etc...
Yes it certainly did...well remembered Richard!
Welcome to TM redjellybean! The cable snapped on my 2010 4/4 ....just as I was pulling up to the start line at Shelsley Walsh at the end of the MAC Rally. My swearing is captured on video somewhere in the net!
The problem was down to a batch of poor quality brake cables....they can be identified by a much coarser reinforcing wire in the outer sheath The tight bend of the cable into the brake back plate can eventually cause cracking of the plastic casing, the reinforcing wire rusts then eventually snaps which then rubs the inner cable.
Whilst my current car has an earlier cable, I've wrapped a few layers of tape around that area and check it every now and again.
Mine snapped at just over a year old....I was shocked that it wasn't covered by warranty...but it's treated as a consumable. As it is with many other car manufacturers.
On some cars....like Cains by the sound of it....the cable is easier to get out than others. Mine was firmly held in by p clips and shirt of cutting holes in the floor from underneath, I had to strip out the prop shaft cover....which meant taking the seats out! The hardest part actually was getting access to the end of the cable in the rear brake. The hub plate gets in the way. I couldn't manage it...nor could Mike Duncan. His son Ben ended up,taking the hub off to access it!
I do hope that you manage to get it sorted without too much trouble.
