Definition of a Function. A function is a relation for which each value from the set the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair. Okay, that is a mouth full.
Master cylinder without booster. Single bore master cylinders: These unboosted hydraulic Master Cylinders are actuated by foot effort, via the brake pedal. The brake pressure is related to actuation force and depends on the piston bore size: the smaller the bore, the higher the pressure.
advantage (pedal ratio) and push on the pedal remain the same, the. fluid pressure (PSI) and the stroke both increase. For example, a 100 pound push on the pedal and 4:1 mechanical. advantage (pedal ratio) gives a 400 pound push on the master. cylinder. With a 7/8-inch bore master cylinder, the piston area is 0.60 square. inches and the pressure developed is 400= 667 PSI.
