Compare disc size with almost any other car, and the discs are disproportionately small. I guess budget comes into it, and ten ton plus stops without fade is probably in industry standard.
But add in how easy they warp(ebc in this case) , rust on the inner edge(ebc don't), fade with anything less than 75% pad material, lack bite, feel and servo asdistance I'm sorry, but they're shit and that's that.
Fit for a trip to the shops and back without spilling anything. But that's as complimentary as I can be frankly.
ANY other car has better bite (more servo assistance) than the omega. Not a mark on the power of the brakes capability fair enough but, Add in a bit of pad ware, some rusty discs after a lay up, a hire car while on holiday, and the poxy things can catch you out first time you stop when back in an omega.
These, ladies and gents, over the life or a set of discs and pads are.... SHIT BRAKES.
Lets lay our cards down then.
I'd class myself as reasonably hard on brakes. If you stop before the white line, you've clearly braked too early.
To quote Mr Darth Loo-knee, I "drive like a cock".
The only discs I've warped have been pattern ones. You say your patterns are warping - I'm not surprised, most do if properly used.
I tend to use TC pads on the Bullet, and OE on TBE. I'd say neither were more tolerant to abuse, in fact both seem to be about the same (excluding the fact that TC lack bite/feel when cold). Beyond half worn, TC pads are spent. Don't be tight, bin 'em (thats a msg to all, not to Gixer). Not sure about OE, as Mrs TB tends to use that car.
The pedal has more travel than most modern cars. Thats personal preference if you prefer/hate that. As all know, I've had the misfortune to own a Focus, fart in those cars, and you go through the windscreen. So I prefer more pedal control, even if it is often used as a switch 
As said in previous post, Mr Gixer, you are a special case. We cannot make recommendations/sweeping statements on what we need is the norm for all OOFers
. And the MV8 will need uprated everything, obviously.
So, yes there are clearly potential improvements to be made, but the cost/benefit/insurance hassles factored in for many OOFers isn't viable. For most, the brakes aren't "shit" 
Couldn't agree more - silly to make sweeping statements based on a "one off" case - just puts most of the other members off due to "bad" information. Not sure I would necessarily describe Mr Gixer as a "special case" though in the light of his rather silly and pedantic posts on this topic.
We need to recognise the Omega was built quite a few years ago now, as a comfortable cruiser, not an out and out racer, and the brakes, in good condition, were at that time adequate and "fit for purpose" for the drivers these cars were aimed at. I drive fast and am considered "hard" on brakes, but do not drive stupidly on the roads. If you want to drive like that try it on a race track (on a track day preferably as you wont last long racing) - if you want to put an Omega on a race track I agree brakes amongst a lot of other items would definately need upgrading.
Or buy a more modern design car with more modern brakes 
Or, upgrade the brakes on the omega. Sigh...
I would also argue, that completely ignoring driving style, speed, or heavy on brakes approach, that the hopeless level of servo assistance on the omega becomes more and more of an issue as time goes on. As jumping between cars highlights. Get in another car, and the servo assistance is massive, and once your used to it give much better control over the omega for much less effort.
The mondeo and focus are not over assisted, they are more assisted than the average. As all things are relative, you have to then conclude that relative to other cars, the omega brakes are massively under assisted. Arguably, as mentioned earlier with slightly low pads, rusty discs after a lay up in an airport car park, and being used to a hire car for a week, there's a good chance you'll run on at the next junction.
