They're still used on BMX bikes.

Thanks for the advice everyone! I have ordered some PB Blaster, and hopefully a thorough soaking with that will loosen them up and then I could possibly knock them down a bit with a rubber mallet. As you have all noticed, the corrosion is pretty bad so it may be the case that I'll have to take more extreme measures.

I did try to emery the bolt, but it's just to tight to do it properly or for it to have any effect.

Great to hear that I can get a replacement brake, I had worried that I would have to search for the same brakes.

The PB blaster should be here tomorrow so hopefully that will yield some results.

Thanks again for the advice. It's much appreciated.

I don't think emery would be useful until disassembled.
You want to remove corrosion from the mating surfaces inside
once it is apart.
