A bit of light progress

Today's main achievement: finished de-rusting, wire-brushing and painting the caliper brackets. They look great, something which cannot be said for the kitchen after I've spent this evening working in it (it's warmer than the garage...)

Also spent much of the evening dismantling a caliper. Three of the four looked OK, but one was missing a dust boot, which means dismantling it, checking for damage, and replacing all the rubber seals, and maybe the piston. After careful use of compressed air to blow brake fluid around the kitchen, but not achieve much in the way of piston movement, the hammer and the clamp were deployed. Eventually (after a couple of hours) the piston came unstuck, and I was able to inspect it for wear:

There are a couple of very small marks (they seem convex, so I think they may be bits of rubber seal where the piston has sat in one place against the seal for a long time, as opposed to concave scratches), but I don't know if these are serious enough to prevent re-use of the piston.

The caliper itself looks OK, with no obvious marks to the bit where the piston slides in, so I think that should be fine to reuse.

Some progress on the wiring and missing parts: the engine seller has promised to post the missing bits (but has not actually done so), and some better progress on the chassis and kit, which will be arriving in two weeks time.

There is an awful lot to do if we are to be finished preparing all the donor parts by then...
