Solid plug the brake line ports on the master cylinder test pedal, if solid pedal the problem is down stream of the master cylinder, if pedal is soft line ports plugged the master cylinder is the problem.
If do replace it, be sure and follow the included instructions for proper bench bleeding method to avoid damaging it in the process.

Re pedal
Have changed master,think I might pinch off brake flex hoses with plastic line plyers and see if the pedal gets hard,could be flex hoses weak,if no change,repeat at rear flex hose and check pedal.just thought about this!
