Put the refurbed front calipers on today.
Took the driving members off and cleaned the old gaskets and sealer off and replaced new gaskets while I was on.
Cleaned the rear wiring loom with good cloth and hot soapy water. The electrical tape was worn through in places, but the wires inside were fine. I re-taped the lot and it looks brand new. Hard to tell in the picture though.
I threaded some garden wire through the chassis from front to back and pulled the wiring loom through the chassis rail. Bit fiddly getting the three electrical connectors through the hole in the chassis, but didn't take long. I taped them down to the loom so they slid out more easily.
It's slowly coming together.
