<p>In a brake booster (10) for an aircraft having an adjuster mechanism (24) with a tubular member (54) that engages a head (62) of a stem (40) to hold an actuator (20) in a fixed rest position after each brake application. The tubular member (54) has a plurality of openings (58, 58'...58") located at various intervals along its axis. The head (62) engages the tubular member to sequentially expand the material between the openings (58, 58'...58") on movement of the actuator (20) toward the friction disc in a brake. After the head (62) has passed an opening (58, 58'. . .58N), the material contracts to a neck down diameter that is substantially equal to the initial diameter of the tubular member (54) to constrain the tubular member (44) with respect to stem (40). Thereafter, any force which attempts to move actuator (20) from the rest position must be substantially equal to the actuation force.</p> |
