Thanks for everyone's help on this I did it after a bit of head scratching the hardest part was the bottom 2 bolts on the bearing assembly as mentioned ,ant ratchet I couldn't get on then I realised if I remove the 2 bolts for the leaf suspension that were in the way ,and then put them back when I'm done which worked but found everything seized and rusted backplate s fell apart cos of rust so had to replace them and replaced the bearing cos they were seized on the backplate s but all done and got a decent handbrake lol oh and 1 caliper seized as well lol thanks again for everyone's help
