The Wacker Neuson Breakaway Kit is a genuine OEM component designed for the APT4T, APT6T, and APT8T electric brake pump series, including standard and cold weather configurations. As a direct OEM replacement, the is manufactured to the same specifications as the original, ensuring correct function within the trailer pump's braking system. This kit fits all six variants across the APT pump family — APT4T, APT4T CW, APT6T, APT6T CW, APT8T, and APT8T CW — making it a single, verified solution for operators running any model in the lineup.
Key Features
- Genuine OEM Braking System Integrity — Engineered to Wacker Neuson's exact brake activation and release specifications, maintaining the precise breakaway response the original system was designed to deliver.
- Drop-In Compatibility — Connects directly into the existing electric brake circuit on APT-series trailer pumps without modification to harnessing or mounting hardware.
- Broad APT Family Coverage — Fits all six APT pump models: APT4T, APT4T CW, APT6T, APT6T CW, APT8T, and APT8T CW, covering both standard and cold weather variants.
- Critical Safety Function — A breakaway kit is a towing safety component; using a verified OEM-spec replacement ensures the trailer's brakes engage correctly in a separation event, keeping the unit compliant with trailer brake regulations.
- Complete Kit Format — Supplied as a full replacement kit so all wear-contact components are renewed together, restoring the system to as-built condition in a single service operation.
A breakaway kit is a mandatory towing safety assembly that automatically applies a trailer's electric brakes if the trailer becomes detached from the towing vehicle. On Wacker Neuson APT-series trailer pumps, this system is integrated with the electric brake setup and must activate reliably under separation conditions to prevent a runaway trailer. When the breakaway battery is depleted or the activation lanyard or switch components are worn or damaged, the system may fail to trigger brakes during a separation event, creating a serious road safety hazard. Keeping this kit in serviceable condition is essential for legal towing compliance and on-site transport safety.
