Understanding the Warner Tension Brake System

Warner Tension Brake System Components

The Warner tension brake system is a crucial component found in many vehicles, particularly those with trailers. Designed to ensure safe and controlled braking, this system can sometimes present challenges. This comprehensive guide delves into the intricacies of the Warner tension brake system, equipping you with the knowledge to diagnose and potentially resolve issues.

What is a Warner Tension Brake System?

The Warner tension brake system is an electric braking system primarily used for trailers. Unlike hydraulic brakes that rely on brake fluid, this system utilizes a series of cables and an electric actuator to apply braking force to the trailer’s wheels. The system is activated when the driver applies the brakes in the tow vehicle. This action sends a signal to the actuator, which in turn tightens the cables, engaging the trailer brakes.

Common Issues with Warner Tension Brake Systems

While generally reliable, Warner tension brake systems can encounter issues over time. Some common problems include:

  • Worn-out brake shoes: Just like regular car brakes, the brake shoes within the trailer’s drum brakes can wear down, reducing braking efficiency.
  • Stretched or damaged cables: The cables connecting the actuator to the brakes can become stretched or frayed, affecting the system’s ability to apply even braking force.
  • Malfunctioning actuator: The actuator itself can experience electrical or mechanical failures, hindering its ability to engage the brakes properly.
  • Improper adjustment: An improperly adjusted tension brake system can lead to uneven braking, decreased performance, or even premature wear of brake components.

Troubleshooting Warner Tension Brake Problems

If you’re experiencing issues with your Warner tension brake system, here’s a step-by-step guide to help you troubleshoot and potentially resolve the problem:

  1. Check the brake controller: Ensure the brake controller in your tow vehicle is properly connected, powered, and adjusted. Consult your brake controller’s manual for specific instructions.
  2. Inspect the breakaway kit: The breakaway kit is a safety feature that activates the trailer brakes if it becomes detached from the tow vehicle. Verify that the kit is properly connected and functioning.
  3. Examine the wiring: Thoroughly inspect all wiring connections between the tow vehicle and the trailer, ensuring they are secure and free from corrosion.
  4. Adjust the brake tension: Use the star wheel adjusters on the trailer’s brake drums to ensure the brakes are properly adjusted. The goal is to achieve a slight drag on the drums when rotating them by hand.
  5. Inspect the brake shoes and drums: Remove the brake drums to examine the condition of the brake shoes and drums. Replace any worn or damaged components.

Importance of Professional Diagnosis and Repair

While this guide provides a basic overview of troubleshooting, it’s crucial to emphasize that diagnosing and repairing brake systems often requires specialized knowledge and tools. If you’re uncomfortable or unsure about any aspect of the process, it’s always best to consult a qualified mechanic or trailer specialist.

“Brakes are not the place to gamble with DIY fixes,” advises Mark Stevenson, a certified automotive technician with over 20 years of experience. “Improperly repaired brake systems can have serious safety implications. If you suspect any issues, always seek professional assistance.”

Maintaining Your Warner Tension Brake System

Regular maintenance is key to ensuring the longevity and reliability of your Warner tension brake system:

  • Inspect the brakes annually: At least once a year, inspect the brake shoes, drums, cables, and all wiring connections.
  • Repack the bearings: Regularly repack the bearings on your trailer’s axles. This helps to prevent premature wear and ensures smooth operation.
  • Adjust the brakes as needed: Adjust the brake tension whenever you notice any changes in braking performance or if the trailer brakes feel uneven.
