I recently purchased a T25 (1983) camper with no MOT. It had been sitting idle for 5 years apparently without MOT, Engine works ok (k-Jet 1.8 out of a Mk2) but I am trying to go over it with a fine comb to fix most of the MOT failure jobs, so that when I do have it MOT'd most should be ok.
Now these are some of the things (no doubt will be more

1) What is the correct name for this? It is the rubber bush that connects to the anti-roll bar support, by the looks of it will that need replacing?

2) Rotten break disc shield. Will this fail in this condition? The plate on the other side is completely corroded and fallen off, do I have to replace it or can i just fully remove it on both sides? If i need to replace whats it called?

3) Breaks, I have looked at the front and back breaks on one side of the van and taken pictures. There seems to be enough pad left on each but its the condition of the discs and drums I'm worried about after its been sitting so long. From looking at the disc / drum pics would i need to replace them too?
Front Disc

Rear Drum

Rear breaks and components

Any help would be much appreciated, I can't wait to get this thing camping

Thanks all
