Re: Definitive au2-au3 brake upgrade thread

Me again,
After completing the S1 to S2 slotted front rotor upgrade over a year ago and then fitting front and back braided lines and a master cylinder brace for less pedal travel , I still noticed the pedal effort was still quite high on my V8,LWB with IRS (heavy).
I then swapped the front Bendix pads for QFM premium pads, this helped but I still feel the effort required is very high (much higher then the Corolla or the wife's FG XR6).
I also recall my AU S2 work car from years ago had much lighter brakes.
I am now considering replacing the booster from S1 to S2/3 if it indeed will help.
I don't think there is a fault with my S1 booster as it holds vacuum for at least a few hours and does not hiss, I suspect the S2 booster is a dual diaphragm type which is probably the key.
If someone could confirm if the swap to a S2/3 booster is the cure, and any tricks besides drilling 4 new holes, please let me know.
Thanks,
Andrew.
