Well after finally putting it off (read being lazy) I've just had a look at my handbrake. I've been able to pull it to near vertical since the bad weather earlier in the year. On looking at the handbrake cable in the cabin, one of the cables had jumped out of the connector, so the handbrake was only engaging the left hand side. Now its all connected back up my handbrake is sticking again but only on the drivers side. (You can hear and feel the handbrake engaged on the drivers side when to attempt to pull off) Where do i adjust the rear brake bias (Can this even be done and then by a car DIY noob?) My car is due its MOT on the 13th of next month so I just need to get it through that and I can then treat it to new pads/discs in the new year.
