Abstract
A brake assembly comprises PA1 (a) a carrier having a bore, and a piston slidable axially in the bore to transmit force of fluid pressure acting on the piston to a brake pad, PA1 (b) shaft structure defining an axis and extending axially to transmit auxiliary thrust to the piston, PA1 (c) a rotary actuator member rotatable about the axis, PA1 (d) coupling device responsive to rotation of the member in one direction to effect axial advancement of the shaft structure toward the piston and responsive to rotation of the member in the opposite direction to allow axial retraction of the shaft structure, PA1 (e) first wear compensation mechanism subject to adjustment to axially shift the shaft structure in response to fluid pressure produced axial displacement of the piston beyond a predetermined amount, and PA1 (f) second wear compensation mechanism subject to adjustment to axially shift the shaft structure in response to rotation of the member beyond a predetermined amount, PA1 (g) the first and second compensation mechanisms being operatively interconnected whereby shifting of the shaft structure by one of the compensation mechanisms serves to effect a corresponding compensating adjust…
