Air Brake System Inspection: Workshop Best Practices

Air brake systems remain the backbone of heavy-duty stopping performance, yet minor leaks and worn components often go unnoticed until a failure occurs. Workshops should treat air system inspection as a core part of every brake service, not an optional add-on. Technicians should verify compressor performance, dryer function, line integrity, and chamber stroke within manufacturer limits. Moisture in the system is a leading cause of valve malfunction and should be addressed through regular cartridge replacement. Documenting inspection results helps fleet managers track recurring issues on high-mileage vehicles and plan replacements before compliance or safety risks emerge.
