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.
In this case, you will just have brake function to two of your four wheels. People also ask us about single reservoir master cylinders versus dual reservoir master cylinders and basically they just want to know if there is an advantage to using dual reservoir master cylinder versus the single reservoir master cylinder.
