Hello mate, the same thing happened to mine a few weeks ago and it was the brake switch behind the pedal my mate replaced it for me and its wasnt expensive but he did say 99% of the time its the switch that goes and not a fuse. hope it helps. one thing i would say is once its replaced make sure the brake lights come on as soon as you even touch the pedal slightly as mine didnt, they can be adjustable anyway so its easy to amend. hope it helps
