Well if they’re held in by split pins, remove then and then the bolts will pull out. They’re might be stuck, but a good tug with pliers will shift them.
Sometimes easier to do with the calipers still bolted to the forks, means you dont put any force on the hoses & banjos.
As above, my experience of brakes on 80’s bikes is that the pins were held by a clip or pin of some sort - usually split pin or r-clip but c-clip is also possible. Even without the clip or pin the tension of the spring holding the pads in place means that the pins would stay in place. If the pins are removed or absent, the you just grip the pins in mole grips or whatever and pull. When you get them out you will remember to make sure there is plenty of copper grease on the pins for next time!
One problem is the lack of grease can make the pins get worn so the pads end up in a notch worn in the pins. You should still be able to pull them out, but might need new pins.
there is a little clip of some sort I cannot see what shape it is though, so what your saying is I just need to pull the pin out?I don’t have any copper grease to replace it though. Is there anything else I can use?
what bike is it ?there are loads of differant types , if it is pins that are holding them there is a good chance they are siezed in , you may be lucky and you might be able to get to the other end ( bearing in mind that the pins are probalbly tapered , so they will only come out oneway ) you might be ablle to get a punch in and knock them out but the type of bike would be very useful ??
