    Talking about greasing the pins I have a large pot of high melting grease stuff, that is used on the railways points system, been using it for years now never had trouble with stuck brake pins. Also used it when fitting bolts etc of  mixed metals

    If itís any consolation, I had the same problem with my rear brake caliper at the 40,000 mile Service. I personally believe that the issue is not pin lubrication related, but rather galvanic corrosion between the pin threads and the caliper body. Perhaps Teflon Tape on the threads would mitigate the problem. Perhaps not.

    Either way, itís a piss poor design...

    Hi Dave,
    Sorry Iam late to the party but another way that others can try that have the same problem is to use an easy out screw. Done it once and it worked. Glad yours is resolved.

    Cheers,
    Wayne

    When I get into this situation with tight bolts & screws I soak them with penetrating oil, tap them with a hammer a few times, and wait for a few hours or overnight. This usually works, if not try some of the above remedies.

    It won't, there's still contact.

    Same 2 pot 27mm sliding caliper Nissin design that's been in use since the early 90's as used on many Triumphs, Hondas, Kawasakis etc.

    Just to add that the Brake Pins are Ferrous ( Some form of stainless steel ),
    while the Caliper body is a softer non ferrous alloy, so you need to be especially
    careful if trying to drill seized pins out, or use "Easy Out" type extractors,
    as it would be quite "easy" to damage the softer caliper body
    and end up having to replace it at considerable cost.

    Wednesday 16th update.
    Caliper on its way back from Powersport Automotive due to a misunderstanding they painted my Caliper added new st.st. pistons and pad pins. Should be here tomorrow, Iíll post a picture and a copy of the bill. Just need to fit the Caliper and bleed the system the back o the road again.
