Hi Team, I have a no brake pedal pressure problem. I believe I've isolated the issue to the Brake Booster rod, either to short or to long.
1st - is the rod adjustable
2nd - if the answer to the above is yes, how is it done.
3rd - what length should it be

application: WB PVan Disc/disc, MC is new P7953, double diaphragm booster, systems been bleed rear to front at least twice, no fizzy fluid at any corner.

I'm hoping someone can assist.
