Hello, think you definitely have two different issues going on here. Brake pedal going rock hard could be lack of servo assistance, but you say the handbrake is slack, so are the brakes stuck on? If so maybe jack up rear wheels and see if they will spin. I have know rear brake linings on other vehicles to come adrift locking up the wheels.
As for your electrical problem I would also go for bulbs, holders, wiring short to rear loom, earth fault.

well a week today and my brake servo will be here, just the brake lights to sort, and do have electrician coming to give me a hand so hopefully back on the road next sunday :serious:

So should have posted this about a month ago, back on the road at long last, got the brake servo swapped and that sorted out the seized breaks, brought a new brake switch, connected it and hay presto lights going on and off as should do. Put everything back to together turned the lights on and brake lights stuck on and console lights coming on when pressing the pedal, so got that ****** off with it took it into the workshop stripped everything electrical off the back cleaned polished sanded every single connection even cleaned inside the light cluster and tow bar housings, put all this back together and whatta you know all working, so what ever it was was somewhere on the back end i can not tell you what as i cleaned it all in one go, but its done and i'm driving the cruise control was also a new switch on the break pedal, so all in all there was a bad connection on the electrics on the back, break light switch and cruise control switch on the pedal and the break servo so got all that sorted and now the central locking off the key fob has started to play up, have to love the nissan....

Well at least you have it sorted.

It is unusual for the brake light switch to cause a problem, although you are not the first.

Interestingly, the service schedule says to change the brake fluid on alternate services, not often done. I wonder if that contributed to the servo failure?

my thinking and i could be wrong but the break servo is working of the vacuum and nothing to do with the oil

The servo is powered by a vacuum but the hydraulic brake fluid deteriorates over time, especially if it gets very hot. The hydraulic system can also suck in tiny amounts of air when brake pressure is released, as the seals around the pistons age....

For sure, I believe brake fluid is hygroscopic too.
