Ryder,
Would suggest that unless you change to more appropriate calipers, a bias bar set-up, without a booster in a road car would be a backward step. You lose the safety requirements of a dual line system and also considerable pedal power without the booster. The booster enables a far greater displacement of fluid,
that sliding calipers - typically GM / Holden depend on to operate effectively.
If better brake balance is what you are after, you may be better ensuring you have compatible calipers front and rear, with the correct master cylinder bias. There are some good caliper options in earlier Harrison brake threads. Murray
