Abstract

A rail vehicle brake assembly (100) acts on a rotating member (110) via first and second friction members (121; 122) movable between a respective engaged position (P_ENG) in which the friction members (121; 122) contact the rotating member (110), and a respective disengaged position (P_DIS) in which the friction members (121; 122) are at an idle distance (d_IDL) from the rotating member (110). An actuator (120) obtains a control signal (CS) and in response thereto controls the friction members (121; 122) to attain the respective engaged position (P_ENG). An adjuster mechanism (130) controls the friction members (121; 122) such that they in the disengaged position (P_DIS) are positioned within a joint margin range (d_m) from the idle distance (d_IDL) notwithstanding any wear (w). The adjuster mechanism (130) has a probing arrangement (131) controlling the friction members (121; 122) such that an activated distance (d_a) separating them from one another in the engaged position (P_ENG) decreases according to a monotonic function as the first and second friction members (121; 122) are worn (w). The probing arrangement (131) sets the activated distance (d_a) by an interaction between a slidable member (133) and a fixed-position member (135) that interact with one another along a contact profile containing an angled segment (T).
