If you are going to convert then it isn't a matter of can you stop - but can you stop over and over again without fading your brakes - and the 70s setup wont cut it.
This could just be my engineer though - and perhaps Victorian rules over other states perhaps?
That engineer is just being lazy cos it's what the Jap car had. Take into effect weight of the 2 vehicles and for a bus you need better brakes and for a bug lesser brakes to have similar braking capabilities of the Jap Car. Also the Jap car's weight is in front so you get more weight transfer under braking that a T1 or T2. Therefore you need larger rears to compensate for the extra engine weight etc.
For the money you pay some of these Oz engineers aren't too crash hot and just do things lazily. Yes there is plenty involved in designing brakes but if you gonna get advise they should know this stuff otherwise why pay $200ph????
For a Bus I'd suggest looking at Porsche brake systems to try and get an idea of the bias needed for a rear engined high powered vehicle. You don't have to use porsche stuff but oonce you know MC and Caliper piston sizes you have the front/rear bias and can figure other manufacturer brakes to fit your need
