So I finally managed to rebuild my powder coated rear calipers.
I moaned before about the what the company did - I wont be using again did by not blocking up openings/threads - the bores had been blasted and rough, so these needed honing. The threads for the brake line and bleed were also messed up - they were very close to being scrap.
The tubes in the carriers for Sliders, they managed to powder coat just inside these too, had to use a drill to clean this out - got all this shizzle out:
What I had screwed up on my previous attempt was the circlip holding the handbrake mechanism into the caliper body, they are tricky as the tool need to have both the reach and fine tips. The only ones I have - or even could find - turned out they would foul on the inner handbrake mechanism. This was stopping the circlip getting to the groove by about 3-4mm. The only solution was to modify them to clear by filling them down:
Plus the mechanism stands proud, so it has to pushed into the body, I came up with this G clamp arrangement amongst the mess of my bench - no wonder I cant find the sliders!:
So after all this effort, with new sliders (gave up the search), cunifer pipe & brass fittings - the reward is this:
Hopefully I will get round to swapping these out soon, but need to prioritise the rusty spots over these.
The Golf still has some parasitic drain, someone posted ignition switch was possible culprit and there was a revised part, so swapped it out for a £13 Topran one - will see if there is any change, starting is pretty lazy after a few days parked up.
Opened up the old one, looks like its had some heat damage:
