I finished painting the rear foot peg hangers, just got to lacquer them tomorrow.
Then I had fun stripping and refurbishing the rear brake caliper.
I figured that it would be better to do the rear first, since there's only one pot and, if I screwed it up, it would be less critical than buggering up a front oneĀ :eek
First problem was that I needed to remove the piston, but needed "low pressure compressed air" to do it, according to Hayes.
I tried with an airbed foot pump, but couldn't get a good seal, so I looked at it a bit more and realised that the bleed valve is almost the same size as a Presta valve on a bicycle tyre.
I found a 10mm bolt to block the hole that the banjo bolt goes into and tried to push the piston out. I got a good seal, but it wasn't moving, so I got a G Clamp and put some padding on each side, then used that to squeeze the piston back into the caliper a little way.
Then, when I tried the bike pump, I got the piston to slide out nicely :thumbup
I found the best way to get the seals out of the caliper was with the pointed "clip" section on the end of a biro cap and then it was just a matter of cleaning everything up and reassembling it.
So tomorrow I do the front calipers and then just wait for the vacuum brake bleeding kit I ordered from eBay to turn up so I can refill the system and check that it all works... (fingers crossed!)
