Should automatic slack adjusters on S-cam brakes be checked regularly?

Automatic slack adjusters on S-cam brakes play a critical role in maintaining the correct brake functionality by adjusting the slack in the brake system automatically as the brake shoes wear down. However, while these devices are designed to self-adjust, it is essential to regularly check them to ensure they are functioning correctly and maintaining the appropriate adjustment.

Regular inspections help identify any potential issues before they lead to brake performance problems, which can affect safety. If slack adjusters are not checked, there is a risk that they might fail to adjust properly due to wear, corrosion, or mechanical issues, leading to brake drag or reduced braking efficiency. By ensuring regular checks, you maintain proper brake system operation and enhance vehicle safety.
