S-cam drum brakes – the most common air foundation brakes on the road – are a familiar sight to every wheel-end technician in the North American trucking industry.
As part of its Bendix Tech Tips series, Bendix Commercial Vehicle Systems LLC offers preventive maintenance guidelines for S-cam foundation brakes that can elevate the effectiveness of regular brake jobs.
“It’s easy to view preventive maintenance as a quick adjustment, grease job, and new brake pads, but there’s much more to it,” says Kevin Pfost, Technical Service Coordinator, Bendix Spicer Foundation Brake LLC (BSFB).
“Paying attention to a few key details during a routine brake job can have a major impact on keeping trucks on the road and in good working condition, reducing maintenance costs, and improving safety.”
