Automatic slack adjusters _________.

Automatic slack adjusters need to be checked regularly.

Automatic slack adjusters are components of air brake systems that are responsible for maintaining the proper clearance between the brake shoes and the brake drum. They automatically adjust the brake shoe position as the linings wear down, compensating for the lining thickness loss and ensuring consistent braking performance.

While automatic slack adjusters are designed to self-adjust, it is still important to check them regularly to ensure they are functioning properly. Regular inspections help identify any potential issues, such as maladjustment, wear, or damage, which could affect brake performance. Checking the automatic slack adjusters allows for early detection of problems and timely maintenance or repair.
