A method of assembling a power brake assembly including a brake booster and a master cylinder defining a chamber disposed between at least one reservoir port and at least one brake line port begins by inserting the master cylinder into the brake booster. The method proceeds by monitoring for a pressure differential between the at least one reservoir port and the at least one brake line port of the master cylinder during the insertion step, and then ceasing insertion of the master cylinder into the brake booster in response to sensing a pressure differential. The method proceeds by withdrawing the master cylinder a distance from within the brake booster; and securing the brake booster to the master cylinder after retracting the master cylinder the distance.

Method of assembling a power brake assembly

A master cylinder assembly of the type comprises a housing () disposed along an axis (A) defining a chamber () having a cylindrical shape extending horizontally between an open end and a closed end. A first cylinder () and a second cylinder () are disposed for sliding movement axially along the axis. Each of the cylinders includes a cylindrical wall () defining a cylindrical bore (). A piston () is disposed in each of the cylindrical bores. The cylindrical wall of each cylinder includes a cylinder ramp () to define a cylinder ramp shoulder (). Each piston includes a piston ramp () to define a piston ramp shoulder (). The piston ramp shoulder () of each piston and the cylinder ramp shoulder () of each cylinder radially engage one another in an assembled position to allow the cylinders () and the pistons () to abut one another during the sliding movement axially along the axis within the chamber of the housing.

Master cylinder assembly in brake system

A brake-by-wire braking system including a braking unit, an electro-hydraulic actuator in fluid communication with the braking unit by way of a first fluid path, a master cylinder in fluid communication with the braking unit by way of a second fluid path, a normally open solenoid valve operatively associated with the second fluid path, and a control unit adapted to actuate the normally open solenoid valve, wherein actuation of the normally open solenoid valve generally fluidly isolates the master cylinder from the braking unit.
