What Tools and Components are Needed for a Trailer Brake Conversion?

To perform a trailer brake conversion, you will need a specific set of components and tools to ensure a safe and professional installation. The primary hardware required is either a hydraulic disc brake conversion kit (which includes calipers, rotors, hoses, and fittings) or an electric over hydraulic brake upgrade kit featuring a 12V actuator.

For the installation process, essential tools and materials include:

• Calipers: For measuring axle dimensions, width, and hub faces to ensure compatibility.
• Torque Wrench: Used to secure rotors to the axle hubs (set to 80-100 ft-lbs) and to tighten caliper bolts (set to 25-30 ft-lbs).
• Flare Fittings and Hoses: To connect the hydraulic lines from the actuator to the calipers.
• DOT 3 Brake Fluid: Required for bleeding the system to eliminate air from the lines.
• 12V Power Source: To test the actuator wiring and connection to the brake controller.
• Safety Gear: Including gloves and eye protection.

Before beginning, it is important to measure your bolt patterns (such as the common 5 on 4.5 inches) and identify your axle type to ensure all components match your trailer’s specific load ratings and spindle types.
