Types of Slack Adjusters

Slack adjusters are mechanical devices used to adjust the tension on brakes and other components of heavy-duty vehicles. There are two main types of slack adjusters – manual and automatic.

Manual Slack Adjusters

Manual slack adjusters are the most common type of slack adjuster used on heavy-duty vehicles. They are manually operated and require a wrench to adjust the tension on the brakes. Manual slack adjusters are typically used on vehicles with drum brakes, as they are easier to adjust than automatic slack adjusters.

Automatic Slack Adjusters

Automatic slack adjusters are the most advanced type of slack adjuster. They are connected to the vehicle’s brake system and automatically adjust the tension on the brakes. Automatic slack adjusters are typically used on vehicles with disc brakes, as they are more efficient and require less maintenance than manual slack adjusters.

Conclusion

Slack adjusters are essential components of heavy-duty vehicles, as they allow the brakes to be adjusted easily and quickly. There are two main types of slack adjusters – manual and automatic – each of which has its own benefits and drawbacks. Ultimately, the type of slack adjuster used depends on the type of vehicle and its braking system.
