Introduction
Unlocking the brakes on a Talbert 20-ton tag trailer can sometimes be a challenge, especially if they have become engaged during storage or if the trailer has not been in use for an extended period. A malfunctioning brake system can cause safety hazards and affect the overall performance of the trailer. This guide will walk you through the steps to safely unlock the brakes, troubleshoot common issues, and ensure the trailer is ready for transport.
Why Do Brakes Lock on Trailers?
Brakes can lock on trailers due to several reasons, such as:
Unlocking the brakes on a Talbert 20-ton tag trailer is a straightforward process that can usually be resolved with a few basic steps, such as releasing the parking brake, checking air or hydraulic pressure, and inspecting for rust or debris. By following the steps outlined in this guide and performing regular maintenance, you can ensure that your trailer’s brakes remain in good working order and avoid potential safety hazards. If the issue persists despite following these steps, it’s important to consult a professional mechanic to diagnose and fix any underlying issues with the braking system.

This guide will walk you through the steps to safely unlock the brakes, troubleshoot common issues, and ensure the trailer is ready for transport.
Why Do Brakes Lock on Trailers?
Brakes can lock on trailers due to several reasons, such as:
- Parking Brake Engaged: The most common reason for locked brakes is that the parking brake has been engaged and the air or hydraulic system has not been properly released.
- Air or Hydraulic Pressure Issues: For air-braked trailers, low or no air pressure can cause the brakes to remain locked. Similarly, hydraulic systems can also fail to release the brakes due to pressure issues or leaks.
- Rust and Debris: Rust buildup and debris on the brake components can cause the braking system to seize up, preventing it from unlocking.
- Faulty Brake Components: Worn or damaged brake shoes, air valves, or other brake components may prevent the system from releasing.
- Check the Parking Brake Lever
- Ensure the Parking Brake is Disengaged: The first step is to check that the parking brake lever or valve is in the released position. If it's engaged, it will hold the brakes in a locked position. Release the lever or valve to ensure the brakes are disengaged.

- Check the Air or Hydraulic System
- For Air-Braked Systems: If your Talbert 20-ton tag trailer is equipped with air brakes, check the air pressure gauge to ensure that the system has sufficient air pressure. A drop in air pressure may indicate an air leak, which can cause the brakes to lock.
- For Hydraulic Systems: If the trailer uses hydraulic brakes, check the hydraulic fluid level and inspect for any leaks or pressure issues in the system. If the fluid level is low, top it off and check for any hydraulic lines that may be damaged or disconnected.

- Release the Emergency Brake (If Equipped)
- Some Talbert trailers are equipped with an emergency brake system that requires manual intervention to release. This may involve pulling a release pin, adjusting a manual valve, or pressing a release button. Refer to your trailer's manual for specific instructions related to the emergency brake system.

- Inspect for Rust or Debris
- Visually Inspect the Brake Components: If the parking brake is released and the air or hydraulic systems are functioning correctly but the brakes are still locked, inspect the brake components for any signs of rust, dirt, or debris. These can accumulate over time and prevent the brakes from releasing.
- Use Penetrating Oil: If rust is present, spray a penetrating oil (such as WD-40 or a similar product) onto the brake components. Allow the oil to sit for a few minutes to loosen the rust. Use a hammer or mallet to gently tap the brake components to help break the rust free.

These can accumulate over time and prevent the brakes from releasing.
- Manually Release the Brakes (If Necessary)
- For Air-Braked Trailers: If the brakes are still locked, manually release the spring brake mechanism by pulling the emergency release knob or valve. This should free up the brakes. If the system still does not respond, it may be an issue with the air valve or a malfunctioning spring brake assembly.
- For Hydraulic Brakes: If the hydraulic system is not responding, check for a manual release valve, often located near the brake cylinder or master cylinder. Open the valve to release pressure and free the brakes.

If the system still does not respond, it may be an issue with the air valve or a malfunctioning spring brake assembly.
- Test the Brake System
- After unlocking the brakes, it’s important to test the entire brake system before moving the trailer. Apply the brakes lightly and check if they release correctly. If there’s any resistance, noise, or unusual behavior, stop immediately and inspect the system further.
- Check the brake pads and shoes for wear, ensuring that they are in good condition. If there is any concern about the brake performance, consult a professional mechanic for further evaluation.

- Low Air Pressure
- If your trailer has air brakes and the system is low on air, the brakes will stay locked. Ensure the air compressor is functioning correctly, and check for any leaks in the air lines. If the air pressure does not rise to the recommended level, it could indicate a leak or malfunction in the air system.

- Hydraulic System Pressure Issues
- For trailers with hydraulic brakes, pressure issues can be caused by low fluid, air in the system, or faulty hydraulic components. Bleeding the hydraulic lines or topping up the fluid may resolve these problems.
