What should you do when checking slack adjusters on s-cam brakes?

Answer: A — Use gloves for protection

When checking slack adjusters on s-cam brakes, it is essential to prioritize safety by using gloves for protection. Slack adjusters are crucial components that help maintain proper brake function and performance in heavy vehicles. When inspecting them, it is possible to encounter sharp edges or moving parts that could pose a risk of injury. Wearing gloves helps protect your hands from potential cuts or abrasions while working around these mechanical components. Other methods that do not involve gloves or adequate safety measures may expose you to unnecessary risks. Inspecting these components requires careful handling and attention to ensure that you work safely and effectively. The use of gloves fosters a safer working environment, allowing you to focus on ensuring that the slack adjusters are functioning correctly without the distraction of safety concerns.
