Slack adjusters, also known as brake adjusters, play a critical role in the safety and efficiency of your vehicle’s braking system. Over time, they may get out of sync and need adjusting. In this guide, we’ll walk through the process of adjusting slack adjusters.
What You’ll Need
- Wrench for adjusting the slack adjuster
- Gloves for safety
- Safety glasses
- Chock blocks
Steps to Adjust Slack Adjusters
Step 1: Prepare Your Vehicle
Begin by ensuring your vehicle is parked on a flat and stable surface. Use chock blocks to secure the wheels and prevent any unexpected movements. Remember, safety is paramount.
Step 2: Locate the Slack Adjuster
The slack adjuster is typically located on the air canister of the brake assembly. Look for a device with a metal rod and a bracket.
Step 3: Loosen the Slack Adjuster
Use your wrench to loosen the adjustment bolt on the slack adjuster. Turn the bolt counter-clockwise to loosen it. Be sure not to remove it entirely.
Step 4: Adjust the Slack Adjuster
Turn the adjusting bolt clockwise until you feel resistance. This tightens the brake. Once you feel resistance, back off the bolt 1/4 to 1/2 turns. This is the optimal position for most slack adjusters.
Here’s a simple reference code that can guide you in the process:

Step 5: Check Your Work
Once adjusted, check the brake chamber rod. It should retract without any delays. If it doesn’t, you may need to adjust the slack adjuster further.
Final Thoughts
Adjusting slack adjusters is a crucial part of maintaining your vehicle’s braking system. It’s a simple process that, with practice, will become easier to perform. Always remember to prioritize safety when working with vehicle parts, and don’t hesitate to consult a professional if you’re unsure.
