Hi Richard, I'm not familiar with that style of parking brake mechanism,but would it be possible to drill and tap a thread in the remaining part of the pin?
I'm thinking you could then try and draw the pin out with some kind of puller or slide hammer. Although access might be a problem.
Just a thought, but hang tight someone else may chime in with an alternative/better idea.
