BRAKE ADJUSTING MECHANISM

摘要

An adjuster assembly (48) for automatically maintaining a uniform release clearance (and therefore a uniform stroke) for brakes and similar equipment. The adjuster assembly (48) comprises a continuous tube (62) and an expansion member (58) together having a combined length controlling the release clearance of selectively engageable friction parts. The expansion member (58) has an expansion device frictionally engaging the interior of the continuous tube (62) to effect progressive circumferential expansion of the continuous tube (62) when the expansion device is axially drawn through the continuous tube to compensate for wear of the friction parts during actuation and release of said selectively engageable parts. Unlike prior art adjuster assemblies, the continuous tube (62) advantageously has an end portion (70) processed differently from the balance of the continuous tube (62) for extending the usable portion of the continuous tube.
