When you’re hooking up trailers for another day of hauling grain, livestock, or equipment, the last thing you need is brake system problems. Agricultural trailer brakes face unique challenges – heavy loads, varying speeds, exposure to moisture and corrosive materials, plus long periods of sitting idle between uses. This 3/8″ BSP trailer brake coupling provides the reliable connection between your tractor’s brake system and your trailer’s braking mechanism, ensuring you’ve got proper stopping power when you need it most.
What You’re Getting
- 3/8″ BSP thread size fits standard agricultural brake line systems
- Durable construction designed to handle farm conditions and heavy loads
- Precise threading ensures secure, leak-free connection to prevent brake line contamination
- Direct replacement part that installs without modifications or special tools
Built for Real Farm Work
FAD axles are widely used on agricultural trailers, slurry tankers, grain carts, and heavy-duty farm equipment. Whether you’re pulling a grain wagon to the elevator, moving a loaded manure spreader, or hauling equipment between fields, this coupling handles the connection that keeps your trailer brakes working properly. It’s designed to work with the brake systems found on general purpose agricultural equipment across multiple brands.
Made to Last
Agricultural trailer brakes face unique challenges – heavy loads, varying speeds, exposure to moisture and corrosive materials, plus long periods of sitting idle between uses. This kit features brake shoes with friction material specifically formulated for these conditions. The coupling’s construction is built to resist the corrosion, vibration, and temperature changes that come with farm use, maintaining a reliable seal season after season.
Installation Notes
Thread this coupling directly into your brake line system using standard pipe thread techniques. Use appropriate thread sealant designed for brake systems – avoid tape that could contaminate the brake fluid. Check for proper thread engagement and tighten securely without over-torquing, which can damage the fitting. Pro tip: When installing new brake shoes, clean the backing plate thoroughly and apply anti-seize to the pivot points and shoe contact areas.
