What component of the braking system is referred to as slack adjusters?

Slack adjusters are critical components in the braking system, particularly in vehicles with air brake systems, such as trucks and buses. They function to maintain the proper positioning of the brake shoes relative to the brake drums. As brake components wear over time, slack adjusters automatically compensate for the wear, ensuring that the brakes remain effective and responsive. This automatic adjustment helps to keep the necessary clearance between the brake shoes and the drums, which is essential for optimal brake performance.

The calibration and adjustment provided by slack adjusters are vital for ensuring reliability and safety in braking. Regular inspection and maintenance of slack adjusters are essential, as any malfunction can lead to uneven brake application or complete brake failure, posing significant safety risks. Understanding the role of slack adjusters is essential for anyone involved in operating or maintaining vehicles equipped with air brakes.
