I agree with the others about bleeding and MC replacement.
Ok, so the brakes get hard after you pump them. Do they stay hard or gradually get soft again?
If they stay hard then you don't need a Master Cylinder - just a good brake bleed.
If they get soft gradually, you will need to replace the Master Cylinder or Rebuild then bleed the brakes.
Reasoning: The Master Cylinder has two units in it - front and back. Each is a separate system. One will keep the brake pedal solid so... if the pedal gets hard when you pump and then gradually gets softer, both systems in the MC are bad indicating a replacement or rebuild of the MC.
Most hydraulic systems will exhibit similar symptoms.
Edit:
It is possible for one of the systems to be failing in the MC and the pedal still be hard. The brakes will work but only on either the front or the back. If you find you keep needing to refill one or the other of the MC fluid reservoirs, this is an indication that one of the systems is failing.
