- Corroded brake shoe hardware or corroded return springs may result in reduced trailer brake performance or failure. Inspect the brakes for any corroded components and replace them as needed.
- Trailer brake pads refer to steel-backed plates that convert kinetic energy into thermal energy via friction. Trailer brake pads deteriorate over time due to normal wear, and should be replaced if thinning or cracks are apparent in the pad lining.
- A loose, main trailer connector can result in insufficient power to an electric trailer brake system. Check the connector to ensure it is secure, as well as ensure the emergency battery is mounted securely and contains a proper charge.
