<p>An adjuster assembly (14) for compensating for a brake lining wear in a brake unit (10). The brake unit has a housing (12) for accommodating the adjuster assembly, a brake lever (16) journalled to the housing (12), and means (26) for transmitting displacement of the brake lever (16) to at least one brake lining (20). The adjuster assembly (14) includes a support shaft (42), sensing means (46) for cooperation with the brake lever (16), a drive ring assembly (56) cooperating with the sensing means (46), and an adjuster gear (40). The adjuster gear (40) cooperates with the drive ring assembly (56). To prevent unwanted release of the adjuster assembly (14), the engagement surface (82) is provided with rotation prevention means (84) adapted for releasable engagement with engagement means (80) cooperating with the housing (12) for preventing rotation of said transmission ring assembly (72) in one direction.</p> |
