Hi
Grease
Now applied as advised and shafts have been lightly oiled too.
Brake Pads and Pistons
Diff, you are correct. On both Rear wheels and on the front RHS, the Inner Pistons had seized and the metal backing of the Inner Pads had seized at the top and bottom mating face within the Caliper. This is a lesson to me when servicing, to check that Pistons move at both sides of the Disc, rather than just looking at the front or rear edge of the wearing material, which can look sound and of good thickness.
I have new Calipers coming for the front, a hasty decision perhaps on reflection. If anybody is interested in a set of Calipers for the front, which, on inspection, with Pistons removed, seem ok, I thought that if I obtained and assembled with new Pistons and Seals they would be quite serviceable.
Thank you all for your advice.
