Slack Adjusters
- 295408 PL20 SLACK ADJUSTER (38.1MM OFFSET)The Automatic Slack Adjuster (ASA) is a vital part of the foundation brake acting as a lever, forming the connection between the actuator & the camshaft. When the brake is applied the actuator moves the ASA forward. The worm wheel rotates the camshaft, in turn moving the brake lining toward the brake drum & diss-engages when it reaches the drum. When the brake is released the reacting force drops & the ASA mechanism re-engages. If excess clearance (wear) is in the system, the worm wheel in the mechanism will not return to its original position - it will have indexed. Learn More
