8)  Long-Life Brake Kits:  Brake shoes, rollers, camshafts and shoe return springs for long life brakes are specifically designed as a system for optimum brake performance. These components depend on each other to provide brake performance truck operators can depend on. Using non-OEM spec level components for maintenance or to upgrade from standard to long-life brakes could result in unbalanced braking, poor brake performance or decreased lining life. It's recommended that truck operators use high quality parts to maintain the original system performance, including linings, springs and bushings. When replacing wheel seals, try to use OE-grade seals with proper drivers, and adjust the bearings using appropriate procedures to avoid seal leaks which can damage brake linings.

9)  Air Management System:  Maintaining dry and clean air supply is important to year-round performance of the air brake system. Regular inspection and check for water and contamination in the system reservoirs is a simple and effective way to keep an eye on the condition. In other words, if oil is observed, identify the source and make repairs as necessary.

Check air compressor operation and governor settings by observing system pressure gauges while the air compressor is in operation and when the governor unloads. Replace air dryer desiccant cartridges and filters on a regular basis and use only OEM-approved service parts. For extra protection, consider converting to a dryer cartridge that incorporates a coalescing filter to capture smaller contamination particles.

10) Anti-Lock Braking System (ABS):  Noteworthy is the fact that roadside inspectors do inspect the ABS warning lamp and dash indicator. If ABS faults are present, use the diagnostic help to identify the root cause of the issue. ABS system lights should not be ignored. ArvinMeritor and Meritor WABCO have diagnostic documents available on the web under the category of Literature-On-Demand. It's important to realize that the ABS system provides information that is broadcast on the databus which may be used by engines and electronically-controlled transmissions.

Remember, brakes work as a system. When an original part is replaced by a "will-fit" part, performance of the entire system may be compromised. A will-fitter's parts may offer a lower price initially, but they could cost you more down the road in downtime or reduced performance. So, don't take a chance with a component system as important as your brakes. Replace brake and brake system parts with OEM quality standard parts.
