ABSTRACT:
A power assisted pedal assembly comprises a brake pedal pivotally connected at one end to a lever which is pivotal about a fixed point, the brake pedal having a connection intermediate its ends with an actuating member of a master cylinder to apply an operating force to the actuating member, and a power assistor operable in response to movement of the brake pedal to apply an assisting force to the brake pedal. The power assistor has a force-transmitting member which is separate from the actuating member and which is in force-transmitting engagement with the lever on or close to the line of action of the force applied to the actuating member by the brake pedal. The brake pedal and the lever pivot about the fixed point when the power assistor is operative and the pedal pivots about a point intermediate the fixed point and the connection between the lever and the actuating member upon failure of the power assistor.
