The other thing that can cause this is the master cylinder not returning
properly to the rest position. try lifting the pedal with your toe. Also
worth checking that the pushrod adjustment is right in the pedal box under
the bonnet - the pushrod should not be tight at the end of it's travel - the
cylinder has a spring inside which pushes the piston back "home", the
pushrod need to be adjusted so that it doesn't inhibit this.
Not likely that this is a problem unless something's been changed though.
The master cylinder piston not returning to the home position is quite
likely though, only reliable cure I've found is to replace the bugger,
though in theory they can be stripped, cleaned and rebuilt with new seals.
