A hydraulic brake wear detection apparatus and a method for detecting a degree of pad wear of a brake pad of a hydraulic brake includes a caliper piston located at least partially within a caliper cavity and attached to the brake pad. The caliper piston includes a piston cavity extending from a caliper piston rim into a caliper piston body at a location longitudinally opposite, and spaced from, the brake pad. An internal piston is located at least partially within the piston cavity and is entirely enclosed in an internal space defined cooperatively by the piston cavity and the caliper cavity for reciprocal longitudinal motion with respect to the internal space.
