I think its fixed!!! ??
Today I got to the Landcruiser in to see what the braking fault was.
Thanks all for the suggestions, so to cover all suggestions things I checked were- tyre pressures fine, wheel bearings no play, tie rod trailing arm bushes all solid no movement, flexi brake pipes sll ok and were replaced 12 months ago.
Still pulling to the right when braking, so I then fitted a new rear load valve, fitted new Brembo pads and then bled the brakes, bled them again and bled them some more.
It now brakes in a straight line, no longer pulling one way.
The front pads did look/ feel glazed over.
Again I'd like to thank you all for taking the time to suggest possible faults, you are all a good bunch of people.
