I wouldn't do the bolt trick as you can mung up the mating face at the bottom of the port. If you dont have a set of pliers for clamping off lines, you can do it using a pair of vice grips with a heavy rage to pretect the line. Or if you want to be a bit less cavalier you can cut a small piece of pipe in half lengthwise and use that between the jaws and the hose.
OTOH, if the master was faulty you would probably see leakage down the inside or outside of the footwell, or you would have pedal return issues. In my experience the slave cylinder is more often the culprit.

I was thinking of removing the hose on top of the master and putting a bolt in to block the flow, would that have the same effect as the blocked hose trick?
And if that didn't work I was going to try the old "Banana in the tail pipe"
