Claim 14:
15. A method (200) for extracting an adjuster unit (20) of a brake assembly (25), the adjuster unit (20) comprising a shaft (22) having a proximal end (22a), a gear (24), and a sleeve (26) having a peripheral wall (26a) extending circumferentially around the proximal end (22a) of the shaft (22), the method (200) comprising the steps of:
providing (202) a device (100) having an insert (102) and an actuator (108) operatively coupled thereto, wherein the insert (102) includes a groove (107) in an engaging section (104) of the insert and an inner volume (106),
partially inserting (204) the insert (102) into an inserted state between the peripheral wall (26a) of the sleeve (26) and the proximal end (22a) of the shaft (22), thereby engaging an inner sealing lip (26b) of the sleeve (26) within the groove (107) of the insert (102) and receiving the proximal end (22a) of the shaft (22) in the inner volume (106) of the insert (102);
in the inserted state of the insert (102), transmitting (206), via the actuator (108) operatively coupled to the insert (102), an extraction force (F) to the sleeve (26), and, moving the insert (102) and at least the sleeve (26) of the adjuster unit (20) away from the brake assembly (25); and
wherein the insert (102) comprises a through hole (110) in a longitudinal direction (L) and wherein the actuator (108) comprises a bar (112) arranged through the through hole (110) and a bar actuator (114) operatively coupled to the bar (112), wherein the bar actuator (114) moves the bar (112) away from the brake assembly (25) in the longitudinal direction (L), thereby transmitting the extraction force (F) to the sleeve (26);
wherein a cup (116) has a peripheral wall (118) that defines an inner volume (120) for receiving at least a portion of the insert (102) and a distal section (113b) of the actuator (108, 112), wherein the bar actuator (114) is arranged at a proximal end (116a) of the cup (116), and a distal end (116b) of the cup (116) contacts a section (25a) of the brake assembly (25) that is proximate the adjuster unit (20) such that when the adjuster unit (20) is being extracted, the position of the actuator (108, 112) is fixed with respect to the brake assembly (25).
