A brake pedal feel emulator includes a piston that is movable against the force of a compressible elastomeric body and fluid force. The emulator supplies conventional pedal feel and travel characteristics when the primary and secondary pistons of the brake system's master cylinder are substantially movable due to isolation of the master cylinder from the wheel brakes. The fluid force is supplied by controlling the flow of fluid from behind the emulator piston through a flow restrictive orifice to a conventional fluid reservoir on the master cylinder asse...
[ We claim:] [1.] A brake pedal feel emulator comprising:a rigid body having a longitudinal bore with an end wall;an emulator piston having a post that is slidably received within the longitudinal bore wherein a variable chamber is defined in the longitudinal bore between the rigid body and the emulator piston; andan elastomeric body positioned in the variable chamber wherein the post is slidable toward the end wall compressing the elastomeric body wherein the elastomeric body resists sliding of the post exhibiting a force versus travel characteristic th...
