Yes you can fit an AUII Booster to an EF/EL. You will need to redril your firewall to take the 4 bolt pattern of the AU Booster and you will need an AUII Master Cylinder.

apart from the above mentioned are the AU S2 brake boosters/master cylinders any better than their earlier model EF counterparts?

yes, the series 2 master cyl has a bigger bore allowing more fluid transfer, probably not really noticable on the tiny e series calipers but still an upgrade from the earlier stuff, and the booster being steel is on upgrade on its own....

just a note, im not sure if anyone has had this issue, but when i changed from series1 au plastic booster to series 2 steel booster other than re drilling the firewall there was a difference in the angle of the firewall causing the pedal rod to bind, so i had to space the bottom of the booster 4mm to get the pedal rod angle right.....

Hey Troyman, i've never really removed a brake booster before. I've just purchased an EF Fairmont S1 but the bloke told me he thinks the brake booster is stuffed. How do i remove the brake booster off of the Lane?

Are the bolts on the inside of the car above the brake pedals etc?

I fixed this problem the second time by buying some reflective foil tape & covering the plastic drum

two fold fix;
1- reflective foil prevents heat
2- completely encasing the drum, thereby holding the piece together
