The higher the break strength, the better you'll stop, but if you haven't got ABS, the lighter the car, the more you'll lock up.
High front bias results in understeer in corners if you break into the corner, or mid corner. High rear bias causes the rear wheels to lock up, or cause more oversteer.
Generally, rear engined cars are best suited to higher rear break strength than front engined, they work better with higher front breaking pressure.
I tend to keep them similar, occasionally 1 step higher on the front, as I left foot brake, it depends on your style. I generally like high pressure breaks.
