Can you pump pedal to a higher point? And it hold there under your foot for a while.

Hi I can yes, or lock it with a long piece of wood. How long do I have to hold it for?

Someone else mentioned that G-valve can cause this issue NRC8215?

30 seconds is enough, shows there is no leakage past master seals.
Issue you have then is either there is still air in the system.
Or the brake rod / master cylinder adjustment is incorrect. Just because it was right for the old master does not mean it is right for the new. Only 2/3 mm play needed.
@Harvester in another post here has the opposite issue I recon.

Thanks for your advice, I tried holding the brakes but no luck but another trick has worked as I tried to describe below

Hi I blanked off rear brake brake line from MC and straight away brake peddle becomes stronger not sinking anymore so the rear brakes G-Valve is faulty part number NRC8215.

Now the trouble is it’s not available any longer. What would be the alternative to this G-Valve please?
