To check the brake slack on S-cam brakes, what should you do?

To check the brake slack on S-cam brakes, it is essential to park the vehicle on level ground and chock the wheels. This provides a stable and secure environment, preventing any unintended movement while performing the inspection. By ensuring the vehicle is properly secured, you can safely assess the brake components without risk to yourself or others.

Once parked and chocked, you can visually inspect the slack adjusters to determine if they are within the manufacturer's specifications. Proper checks on S-cam brakes are crucial, as excessive brake slack can lead to reduced braking efficiency and increased stopping distances, posing a safety hazard on the road. Therefore, using the correct method to check brake slack not only follows safety protocols but also ensures the reliability and effectiveness of the braking system in your vehicle.
