Rear left rear right front left then front right high performance fluid should be used to maintain pressure at a high boiling point. hope I'm not talking jibberish :signLOL:

My Ed. 30 has the same 23 mm3 MC and the same brake setup as @th3_f15t. The pedal is firm in any situation. I can put all my weight on it and it won't sink to the floor.
Shoduchi:
Maybe omeydz has a good point.
My GT Sport with R32 front brake setup and 22 mm3 MC does have a sinking brake pedal when stationary. While driving I just have to make a small pressure for the car to stop fast and it never sunk to the floor when I braked hard.

Oh well in that case it's probably not been bled properly.
omeydz:
On my MK6 Iv got R20 345/310 brakes and standard master cylinder ,,, totally oem feel no matter what and good braking power!
th3_f15t:
The brakes are spot on when driving, just when stationary. I bled the system using a pressurised bleeder, going to use slightly better fluid and re-bleed tomorrow anyway just for the sake of it then see how things are. The pedal is getting better as the brake bed in so may just be a teething problem.
Still, an upgraded 25mm master cylinder will still be done at some point, Wilwood Brakes do a range of upgraded MC's so going to save and enquire.
