Sealing device for a slack adjuster

摘要

A slack adjuster includes a boot to inhibit contamination of the slack adjuster and prolong the lifetime of a vehicle braking system. The boot includes an expandable bellows, a first seal integrally formed with the bellows and a second seal integrally formed with the bellows. The second seal is positionable in the cavity of the body and includes a boss. The boss is engageable with the lip to inhibit removal of the second seal from the cavity. The second seal of the boot is inserted into the cavity, and a link is inserted through the boot and into the cavity after the seal is inserted into the cavity.
