Abstract: Caliper brake apparatus has a caliper housing, an actuator including a plunger movable axially longitudinally to urge a lining against a rotating disc, and the lining having the form of a plate which is laterally elongated and defines a plane generally perpendicular to said axis. The apparatus is improved by:(a) the plunger having cross sections in planes normal to said axis and characterized as laterally elongated and as having lateral length dimensions which are substantially greater than the plunger transverse width dimension, the width dimension being generally normal to said axis and to said lateral length dimension, and(b) the actuator having a recess receiving the plunger, the recess having cross sections in planes normal to said longitudinal axis characterized as conforming in shape to said plunger cross sections.In addition, one or more removable end plates may be employed to removably retain the lining in position.

Abstract: A brake assembly comprises(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,(b) shaft structure defining an axis and extending axially to transmit auxiliary thrust to the piston,(c) a rotary actuator member rotatable about the axis,(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,(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(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,(g) the first and second compensation mechanisms being operatively inte

Abstract: A braking assembly includes a carrier for a hydraulically actuated braking piston; a shaft movable axially to also displace the piston, a rotary actuator member, and a coupling responsive to rotation of the rotary member to effect advancement of the shaft toward the piston, accompanied by gripping of the shaft.

Abstract: A braking disc is split into two arc-shaped body sections each having opposite faces for engagement with brake pads; an elongated fastener and a guide pin are located in the space between such faces for releasably guiding and retaining the sections in assembled relation, and thickened ribs and associated bosses with sub-ribs thereon provide parallel bores to receive the fastener and pin, enabling quick disassembly of the sections.
