From what I last heard from my engineer is its fine to go a bias box assembly. .. but it has to be locked so you can't adjust it..ie split pins thru the spindle or a nut to lock it.
Vac booster isn't a problem if removed.. This was my engineer in Adel

cheers for that marty. seem to be told so many different things its hard to work out what you can/cant do. 
the engineer i have been talking to seemed ok with the use of a pedal box assembly but wanted to see documentation
from the manufacturer that it was designated for road use and not just for racing purposes.
in regards to the brake system being boosted he said it would be subject to a simplified ADR brake test. as such he said he would be surprised if it passed the test without a booster but that one is up to me whether to try or not...

Hi Lee,
 
I had a bias box with no booster fitted to my Mk2 Escort when it had to go for a full roadworthy here in South Aust.
I passed the brake test but after inspection they wanted to fail it due to s/s braided feed lines from pots to m/cyls not being ADR approved - luckily I'd done my research to get car up to spec and any brake line not under pressure was not required to have ADR approval as mandatory.
Also yes no remote adjuster allowed.
 
I recommend tuning you brake setup on the brake dynos that some auto shops have. Helps to get bias correct before the test for rego.

This particular does not help a each state is different, its up to the engineer to confirm if they will sign it off, as some may use the ICV ruling and pass it bit charge you alot for a design they may patent.

Depend which year vehicle you have, escort mexico had reverse pedal box, and some perhaps imported in the country, can be used as a basis for, unless transport know it's not a genuine Mexico, would it matter.

In QLD unboosted systems are not allowed with turbo engines, however I've managed to argue the Mexico rule above but have to fit a genuine one, which a VH40 booster would be cheaper.

Which way you go also depends on your insurer
