There are disclosed several embodiments of a disc brake caliper assembly in which adjustment is made for wear on the pads by a non-rotating linearly expandable and retractable linkage arranged between a brake actuator and the pads. The linkage includes inner and outer members coaxially reciprocal without rotation with respect to one another, one member having surfaces which extend at acute angle with respect to the axis and opposite surfaces on the other member which extend parallel to the axis. Circumferentially spaced wedges are disposed in the space between the angled and parallel surfaces, and springs between the first member and wedges yieldably urge the wedges in the first longitudinal direction toward the angled surfaces, the second member being movable during the braking cycle in a second longitudinal direction and thus relatively to the first member, whereby the linkage is caused to expand in order to adjust for wear.

A disc brake caliper assembly, comprising a caliper housing, a disc mounted within the housing, an outer pad between a wall of the housing and one side of the disc, an inner pad on the other side of the disc, and a non-rotating, linearly expandable and contractible linkage, including inner and outer members mounted for coaxial longitudinal reciprocation without rotation with respect to one another, a first of the members having surfaces which extend at an acute angle with respect to an axis and opposite surfaces of the second member which extends parallel to such axis, circumferentially spaced wedge means disposed in the space between the angled and parallel surfaces on the members, means acting between the first member and wedge means to yieldably urge the wedge means in a first longitudinal direction toward the angled surfaces and thus into a wedging relation between the members to restrict motion of the second member in the first direction relatively to the first member, and means operable during a brake cycle for moving the second member longitudinally in a second longitudinal direction opposite to the first longitudinal direction and thus relatively to the first member, whereby the linkage is caused to expand in order to adjust for pad wear.
