Question on Clutch Master and Slave Cylinder Replacement

After replacing my clutch slave on 2003 mini cooper s, the brakes are really hard and don't seems to be working. Is the next step to replace the master brake cylinder, or can it be the clutch slave cylinder isn't bleed correctly?

Thanks

Check if the brake booster is getting sufficient vacuum. It may have been disrupted during the clutch work.
