on some vehicles with "remote" master cylinder and servo,(fitted to the ns of the engine bay, rhd vehicle)
wear can occur in the linkage points,(not very often)

the omega is direct acting and shouldnt require any pedal adjustment.

the diect links are preset and usually loctited. you really dont want them to come loose.

There is a reference in the Haynes manual to using Tech2 to power up the ABS pump to bleed the air out of the deeper recesses of the ABS valve.

I don't know if you could achieve the same effect by driving across some wet grass or gravel and stamping on the pedal?

the problem is servo related we reckon (garage and me).  They found a loose vacumn hose and that has improved it another bit but it's still not right, he reckons the servo needs replacing but i'm going to take another look around at the pipes first....

Update on this, I ended up replacing the front disks and pads and it did improve it somewhat.  It's still not as good as my old Omega but I've gotten used to it and it does stop sharpish once you bury the foot.

The NCT (Irish MOT)showed good braking force from the brakes all round... so i'm inclined to do no more with this.
