The pushrod will come out, you just have to wiggle and twist gently. I use needle nose vise grips. Some times takes a bit of effort. (it is held in there by friction to the release spring) If you damage the end by accident it can be dressed with a fine file.
Check that the release bearing on the slave piston turns freely and is not dry and rusty looking. If it is chances are the slave will need replacing.
If not lube and re-install as per this post: http://www.advrider.com/forums/showp...7&postcount=27
