What is examined with respect to slack adjustors?

The examination of slack adjustors focuses on their alignment with the pushrod because proper alignment is crucial for the effective functioning of the braking system. A slack adjustor's primary role is to maintain the appropriate amount of slack in the brake system, ensuring that brake shoes or pads engage correctly when the brakes are applied. If the adjustor is misaligned, it can lead to uneven wear, reduced braking effectiveness, and ultimately compromise safety.

Alignment ensures that the pull of the brake mechanism is consistent and optimal, allowing the brakes to function as intended. Inspectors look for any signs of wear or malfunction in the adjustment mechanism, making sure it is correctly positioned in relation to the pushrod to achieve the desired braking performance. This aspect is essential in maintaining the overall integrity of the braking system and ensuring safe operation of the vehicle.
