ABSTRACT:
A brake actuating assembly for actuating a master cylinder having a power assistor comprises a brake pedal pivotable about a pivot point at one end and connected at a point intermediate its ends to an actuating member of the master cylinder, movement of the actuator member also actuating the power assistor, the pivot point being connected to a piston of a fluid motor operable in response to the operating pressure of the power assistor the arrangement being such that in normal operation the pressure of the power assistor actuates the piston to hold the pivot point in a fixed position but upon failure of the power assisting means the pivot point is moved to vary the pedal ratio, to permit the master cylinder to be operated without power assistance.
