This subject always really puzzles me. Factory omega brakes are really good.
I’m all for making good progress, but if you’re so hard on your brakes that genuine GM setup isn’t enough, it’s probably time to slow down.
Unless of course we are talking track use - in which case disregard my post
They are good enough (if you don't let the pads wear beyond half way) to a point, but its a big heavy car with, by todays standards, small disks and pads.
Getting across MK on one of the NSL gridroads is enough to cook them if you get it back up to the speed limit and brake reasonably late and have to stop at each roundabout.
I've always maintained the Omega with well serviced brakes is good for about 10 big stops from 70mph in a short period before they're properly cooked, and about half that from 100mph on the local runway (that I can no longer get on
).
Ignoring MK, there aren't too many places in the UK where under normal conditions you can really cook them if they are well maintained, without driving like a real loon, but you can easily get a bit close for comfort on a spirited country lane jaunt.
