This is the point at which the car stops.

When the pedal is delivered, the pressure from the fluid is delivered, causing a decrease in water-driven pressure in the master cylinder. This delivery permits the drum shoes to deliver contact with the drums removing the fluid from the haggles to the master cylinder.
