Safety Information

WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov. Always wear appropriate personal protective equipment (PPE) during installation and maintenance. Ensure the trailer is securely supported before working underneath it. Hydraulic brake systems operate under pressure; exercise caution to prevent fluid leaks and potential injury.

Package Contents

The DEXTER MARINE PRODUCTS OF GA 80326 Single Axle Kit includes the following components:

• 2 - 24" DOT flexible hoses
• 1 - 76" DOT flexible hose
• 1 - 240" DOT flexible hose
• 5 - Cable ties
• 2 - Union "T" connectors
• 2 - "T" clamps
• 8 - Self-tapping screws
• 4 - Cable clamps

Setup and Installation

1. Preparation: Ensure the trailer is on a level surface and securely chocked. Disconnect the trailer from the tow vehicle. If replacing an existing system, drain the old brake fluid and remove old components.
2. Hose Routing: Carefully plan the routing of the flexible hoses from the trailer's brake actuator to each wheel cylinder/caliper. Use the longest hose (240") for the main line from the actuator. The 76" hose can be used for a secondary run, and the 24" hoses for connections to the wheel assemblies. Avoid sharp bends, kinks, or areas where hoses could be pinched or abraded.
3. Connecting "T" Connectors: Install the union "T" connectors at appropriate points to split the main brake line to each side of the axle. Secure these connectors using the provided "T" clamps and self-tapping screws to the trailer frame.
4. Hose Connections: Connect the flexible hoses to the brake actuator, "T" connectors, and wheel cylinders/calipers. Ensure all fittings are tightened securely to prevent leaks. Use appropriate wrenches and avoid over-tightening.
5. Securing Hoses: Use the provided cable ties and cable clamps to secure the hoses along the trailer frame. This prevents hoses from dangling, rubbing, or interfering with moving parts. Ensure there is enough slack for suspension travel.
6. Bleeding the System: Once all connections are made, fill the brake actuator reservoir with DOT 3 or DOT 4 brake fluid as specified by your actuator manufacturer. Bleed the brake system according to your actuator and brake assembly instructions. This typically involves opening bleed screws at each wheel while applying pressure to the brake system until no air bubbles are visible in the fluid. Start with the wheel furthest from the actuator.
7. Leak Check: After bleeding, thoroughly inspect all connections for any signs of fluid leaks. Re-tighten any leaking fittings.
8. Test Functionality: Before road use, perform a static test of the brake system to ensure proper operation.

Operation

The DEXTER MARINE PRODUCTS OF GA 80326 Single Axle Kit provides the necessary hydraulic lines for your trailer's brake system. Once properly installed and bled, the brake lines will transmit hydraulic pressure from your trailer's brake actuator to the wheel brake assemblies, enabling the trailer's brakes to engage when the tow vehicle's brakes are applied. Proper operation relies on a fully sealed and air-free hydraulic system.

Maintenance

• Regular Inspection: Periodically inspect all brake hoses and connections for signs of wear, cracks, chafing, or leaks. Pay close attention to areas where hoses might rub against the trailer frame or other components.
• Fluid Level Check: Regularly check the brake fluid level in your trailer's brake actuator reservoir. Top up with the recommended DOT 3 or DOT 4 fluid as needed.
• Fluid Replacement: Consult your brake actuator manufacturer's recommendations for brake fluid replacement intervals, typically every 1-2 years, to maintain optimal brake performance and prevent corrosion.
• Component Integrity: Ensure all clamps and ties securing the hoses are intact and holding the hoses firmly in place. Replace any damaged or missing fasteners.

Troubleshooting

• Spongy Brake Pedal: This often indicates air in the hydraulic system. Re-bleed the brake lines thoroughly, starting from the wheel furthest from the actuator.
• Brake Fluid Leaks: Inspect all connections and hoses for visible leaks. Tighten any loose fittings. If a hose is damaged, it must be replaced immediately. Do not attempt to repair damaged hoses.
• No Brake Engagement: Check the brake fluid level in the actuator. Ensure the actuator is functioning correctly. Verify all connections are secure and there are no severe kinks in the lines.
• Uneven Braking: This could be due to air in one side of the system, a restriction in a line, or issues with the wheel brake assemblies themselves. Re-bleed and inspect lines.
