Is there a how to guide for adjusting the brake pedal?

There's not much that really bothers me about driving Herman, but his brakes make me think the seals in the master cylinder are permanently on their last legs. I changed the master cylinder for good measure when the originals were showing a sinking pedal under continuous pressure, but that's the only difference between the old (knackered) and the new cylinder. It's not that they don't work, it's that the travel is way way too long and soft. The front discs and pads are uprated but not high temp items and the fluid is new.

I don't know why they bothered with ABS as I don't see the brakes ever exceeding the limit of mechanical grip from good tyres. Unlike my SD1, a car with notoriously c**p brakes, fitted with V12 Jag front calipers that could seriously stop and lock up if you didn't concentrate (4 pot dual circuit with pistons about 3" diameter on a car weighing 1400kg or so). Never did you feel a lack of confidence in that car.

That is just proof that your brakes are not working properly! And it would suggest a master-cylinder fault, whether it's faulty or not bled correctly warrants further investigation.

Which shows your brakes are not working as they should - I can get my ABS to fire at any speed one premium branded tyres in the dry

It might be worth a pm to Serek on here. He's got a few options depending on wheel size. I have 18's that will accept Audi Q7(huuuuge great bus) front callipers and 359mm discs. But they won't fit 17" wheels.

I have them installed under 17" wheels here

One thing to consider when comparing with FWD cars is that the weight distribution of a FWD car will be further forward than an Omega's. This may well mean that the braking has to be biased further forwards, making a larger brake setup at the front necessary to provide equivalent resistance to fade.

the last time I weighed an Omega I got 885kg front axle, 585kg rear axle - which was a bit of a surprise to me !

Woo, fair play. Didn't think they'd fit. Good stuff.

Got a spare pare of calliper adaptors? If needed?

Did they need longer hoses, or hub machining?

[2woody]

got a drawing of adaptors.

no machining needed

....... and I made the hoses
