Hydraulic wheel cylinder

Question

In an automotive brake wheel cylinder with a diameter of 1" and a center fill port with a piston on each end, and a line pressure of 100 psi, do the pistons force total 200 lbs of force or is it still 100 lb.

(=l=)

Answer 1

If you have an automotive brake wheel cylinder that has a piston on each end, and given an applied line pressure of 100 psi, then each piston will exert a force of 100 pounds.

Therefore, the total force exerted by both pistons combined is 200 pounds. Each piston effectively exerts a force of 100 pounds in opposite directions, and their forces add up to provide the total force of 200 pounds.
