Master cylinder

[LowTechRacing]

I have stock drums in the rear and disk in the front. Dont know what master I have now. What master should I get for the most rear via I can get?

Back when we ran astreet stock. We would adjust the rear drum brakes up till they were just dragging. It would help the car to qualify well. At feature time the brakes had worn a bit and we would have a bit more front brake bias. Worked great! Two years and two championships then we moved up. You have to adjust them each week! I hope that helped.
