Unbolt the complete assemly from the fork slider 2x 10mm head bolts and 1 big one.
Turn the pivot so you can support the "ears" of the top pivot on the jaws of a vice and tap the steel pin out allong with pivot then clamp the flat faced bottom of pin in vice ans start wiggling and pulling moving bracket upwards till its off.
Clean the pin and bore of swinging piece, liberally copaslip and rebuid

Whilst you are that far in it's worth replacing the top & bottom O rings one of mine was split.
When I dismantled mine I had some green left over O rings from my Jeep air con repair kit - they were a perfect fit!

That did it. Thanks.

Quick clean, rub over the pin with one of those nylon abrasive pads and a polish. All back together, with new o-rings and coppaslip. Had to relieve the brake pressure to get the calliper back on, quick bleed and good. Test ride at the weekend

ColinHH:
Thanks all. I will certainly remove the pivot pin and follow the same procedure when I rebuild the caliper once the parts arrive from CMSL. But the difference that my temporary fix has made is amazing. Since getting the bike I have really struggled to move it around the garage as it seemed soooo heavy, and I have put about 1,000 miles on it, I’m pretty sure that all that time it has been dragging on that static pad. Took it out for a run yesterday and the difference was significant. I can also move it around the garage with ease. All because of a gummed up pivot pin!

Martin6:
I have written up a service schedule, largely based on the factory workshop manual. I'm going to add in giving the pivot a clean and re-grease every 2 years.

It is quite a vulnerable location, so im surprised this isn't observed more often.
