What is the correct procedure for replacing S-cams in a truck's braking system?

Replacing S-cams in a truck's braking system involves critical components that guarantee the proper function and safety of the brakes. The correct procedure necessitates replacing the automatic slack adjusters and inspecting brake chamber diaphragms.

By replacing the slack adjusters, the system ensures that they function correctly alongside the new S-cams, maintaining proper tension and adjustment of the brakes. This is essential because slack adjusters play a key role in compensating for brake lining wear, ensuring the brakes maintain effective stopping power. Additionally, inspecting the brake chamber diaphragms is vital because worn or damaged diaphragms can lead to air leaks, which would negatively impact the braking system's performance.

This approach to replacing S-cams promotes a holistic maintenance strategy, ensuring that related components are also in good working order, thereby enhancing the overall safety and reliability of the truck's braking system.
