Brake Advise Needed...

I do not remember if you are running a stock style master cylinder or a double master cylinder system with a balance bar between them.
If you are using the stock style master cylinder. You can run into a problem of not using the rear brakes enough. Say you use the complete stock brake system of a donor car. The english roadster style kits have the motor set back lots farther than most stock cars so your percentage of total vehicle weight has been changed with a higher rear weight percent than the donor vehicle had. Meaning that the front brakes will be easier to lock up and the rear brakes harder to lock up. Meaning your front brakes are getting way to much pressure and your rear brakes not enough pressure.

To cure this problem and to use your rear brakes to their full potential you need to add brake line pressure to the rear and take some away from the front at the same time and the only way to do this is with the double master cylinder system with the balance bar between them. Other wise the more you improve the front brakes the less you are using the rear brakes.

You want the front brakes to lock up slightly before the rear so adjust your balance bar so the rear brakes lock up first then adjust back just enough that the fronts lock up first this way you know you are using your rear brakes to there full potential and not over working your front brakes. Be sure not to have much fuel load on when doing this because if you do this with a full fuel load when the tank is almost empty the rear might lock up first. Unless you have a remote adjusting knob so you can adjust the brake bias as you are driving.
