Slack adjuster manual#

So, if you want an automatic or manual slack adjuster built to meet the most rigorous road conditions, choose SilverbackHD. To complete the sealing process, SilverbackHD uses high quality gasketing and thermoplastic resin (TPR) o-rings designed to withstand severe temperature fluctuations and the environment.

Slack adjuster series#

Case hardened and heat treated componentry that meets SilverbackHD Intentional Engineering standards, is built to harmonize with SilverbackHD GeoMetric Series S-Cams and other wheel end components.īecause the SilverbackHD automatic slack adjuster is exposed to the worst road corrosives in the industry, we use a series of rust and corrosion inhibitors to ensure longer life.Īll exposed moving parts are zinc-dichromate plated for optimum corrosion resistance, while the housing is coated with a ferritic nitrocarburizing process. Slack Adjusters Double acting compression slack adjuster enables automatic adjustment, with infinite increments, maintaining proper piston travel and brake. SilverbackHD uses only tool-grade steel, and quality forgings to ensure that every style of slack adjuster will have dependable performance throughout its life. The efficiency of a slack adjuster will depend on the quality of its components. SilverbackHD’s complete line of GeoMetric Series manual and automatic slack adjusters are consistent with the corporate Intentional Engineering® standard.Įach slack adjuster is engineered to exacting standards to ensure ongoing braking efficiency, longer life and seal integrity under the harshest conditions.

The ASA, however, does return to its original position, ensuring constant stroke is maintained.SilverbackHD Automatic Slack Adjusters Intentionally Engineered for Better Braking The Brake Adjusters are automatic slack ajusters available in a wide range of model to address line haul tractor and trailer, severe duty, transit and motor. Built to be robust and reliable, the industrys lightest-weight automatic slack adjuster optimizes brake performance by increasing payload capacity and enhancing camshaft bracket life.

This means the camshaft will also have indexed, keeping a constant gap between lining and drum. Automatic slack adjuster (ASA) for on-highway, linehaul and vocational applications delivers shorter stopping distances and offers longer lining life. 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. When the brake is released the reacting force drops and the ASA mechanism re-engages. This dis-engagement means adjustment is not made for any elasticity within the foundation brake. When the brake lining contacts the drum, the reacting force causes the ASA mechanism to dis-engage. This is the excess clearance for which adjustment is made. If lining and/or drum has worn the ASA mechanism engages and accounts for slack or wear in the system. The ASA continues to move until the brake lining touches the drum. The worm wheel rotates the camshaft, in turn moving the brake lining toward the brake drum.

As fleets strive to ensure their equipment is operating properly and safely this new product will assist.

is introducing the latest innovation in their line of Auto Slack Adjustors, with the new Brake Adjuster with Visual Stoke Indicator. When the brake is applied the actuator moves the ASA forward. Indicator Slack Adjuster TSE Brakes Introduces New Brake Adjuster With Stroke Indicator. The function of the ASA is to compensate for wear in both brake lining and brake drum while maintaining a constant stroke of the actuator. It acts as a lever, forming the connection between the actuator and the camshaft. The Automatic Slack Adjuster (ASA) is a vital part of the foundation brake.
