How To Back Off Bendix Versajust Slack Adjuster

The Bendix VersaJust slack adjuster plays a vital role in ensuring the correct operation of brakes and promoting safe driving conditions. Its main function is to regulate the gap between the brake shoes and the drum, thereby minimizing undue wear on both the brake pads and drums. Nonetheless, the VersaJust slack adjuster can become disaligned or suffer damage over time, necessitating a back-off process to regain its proper operational state.


Before attempting to back off the Bendix VersaJust slack adjuster, it is important to understand its purpose and how it works. The VersaJust slack adjuster is designed to automatically adjust the distance between the brake shoes and the drum as the brakes wear. This ensures that the brakes remain in proper alignment and function optimally throughout their lifespan.

Step 1: Identify the Issue

The first step in back-offing the Bendix VersaJust slack adjuster is to identify the issue. This can be done by inspecting the brake system and checking for any signs of misalignment or damage. Look for excessive wear on the brake pads, uneven tire wear, or any other indications that the brakes are not functioning properly.

Step 2: Disconnect the Air Lines

Once you have identified the issue, the next step is to disconnect the air lines from the slack adjuster. This will allow for easier access and prevent any accidental activation of the brakes during the back-off procedure.

Step 3: Remove the Brake Shoes

To properly back off the Bendix VersaJust slack adjuster, it is necessary to remove the brake shoes. This will provide ample space for adjustments and ensure that the procedure can be carried out safely.

Step 4: Access the Slack Adjuster

With the brake shoes removed, you can now access the Bendix VersaJust slack adjuster. Locate the adjustment nut and loosen it to release any tension on the system.

Step 5: Back Off the Slack Adjuster

Using a wrench or socket, turn the adjustment nut counterclockwise until you feel resistance. This indicates that the slack adjuster is in its fully backed-off position. Be cautious not to overtighten the nut, as this can cause damage to the system.

Step 6: Reassemble the Brake System

Once you have successfully backed off the Bendix VersaJust slack adjuster, it is time to reassemble the brake system. Begin by reinstalling the brake shoes and ensuring that they are properly aligned with the drum. Then, reconnect the air lines and test the brakes for proper function.


Backing off the Bendix VersaJust slack adjuster is a crucial maintenance procedure to ensure optimal brake performance and safe driving conditions. By following these steps, you can effectively restore proper function to your vehicle’s brake system.
