I give up with brake bleeding

[cluxford]

I've just gone through something similar for different reasons. Booster died. replaced it and wow. I think in the 5 years I've owned the car the booster never worked right, as the new booster has the pedal so soft it's crazy and then when it does brake it locks em up.

Didn't have a prop valve it does now.

For me the soft brake pedal is that the car originally had manual brakes, not assisted. The pedal ratio is 6:1 which is not ideal for a boosted application. A 4:1 or 5:1 ratio is what's required.

Assume from reading that article this is something you've also considered. I'm looking for a new pedal now
