So there was a break in the weather today, so another 2 jobs crossed off the list. Fitted a new front corner sensor, works fine. It was a cheapy from ebay, just incase anyone was cautious about buying a none branded one (as I was). If it stops working in a week, I will update, but so far, so good.
I also adjusted the handbrake, as it was not holding the car even on a slight incline. I had googles and reviewed this, and they all said to adjust through the hole in the hub at the bottom (6 o'clock). I could not find the adjustment, so ended up removing the hub (easy job, 4 mins). So just for future reference for anyone else wanting to do this, it isnt at 6 o'clock on the LS430, it is at 9 o'clock.
All in all, 2 jobs well done, that were not too taxing.
