Abstract: A Master Cylinder installed with a servo motor to vary the cross-sectional area of a Plunger Assembly is discussed. The motor is autonomously operated using a Fuzzy Logic Controller which uses sensor input(s) to position its shaft and subsequently change the cross-sectional area of the Plunger Assembly. This intelligent system helps achieve sufficient brake force under the dynamic requirement. The body is made of Al 7075-T6 primarily due to its high strength-to-weight ratio. In light of the corrosive nature of brake fluid at certain values of its pH, electroless-nickel plating of the Master Cylinder part components is also discussed. Dynamic seals made of EPDM rubber have been used due to the constant relative motion between different moving parts.
