Master cylinder pressure question..

Eman · Today, 12:00 PM

Other discussion about MC's and the mention of a MC with 60/40 bias.
Someone explain to me how the MC can have 60/40 bias when the bore in the MC is the same size for both pistons/ports.
I know GM used some step bore MC's where the pistons are different sizes for each port which makes sense using hydraulic principles where the same pressure is applied to 2 different size pistons results in different pressure out of the ports.

The positioning of the "cups" are staggered, which changes the timing of the application of pressure
