The Wacker Neuson Brake Line Kit is a genuine OEM component designed for the HI750 and HI900 series indirect-fired air heaters. This kit covers multiple configurations within those families, including the HI750GM, HI750GM HD Mobile, HI750G, HI900DGM, and HI900DGM Surge Brake variants. As a factory-sourced assembly, every line, fitting, and hardware piece is matched to the original design spec so the surge brake system installs and performs exactly as Wacker Neuson intended. When your brake line shows wear, cracking, or leakage, replacing it with the correct OEM kit is the fastest path back to safe, road-legal towing.
Key Features
- Genuine OEM Hydraulic Integrity — Factory-sourced brake lines rated to the correct pressure tolerances for the HI750 and HI900 surge brake systems, ensuring consistent hydraulic actuation without seepage or pressure loss.
- Complete Kit Configuration — Supplied as a full kit with all lines and associated hardware, so one part number covers everything needed for a complete brake line replacement in a single order.
- Broad HI-Series Compatibility — Verified fitment across the HI750GM, HI750GM HD, HI750G, HI900DGM, and HI900DGM Surge Brake indirect-fired air heater models.
- Surge Brake System Performance — Correctly functioning brake lines maintain full hydraulic pressure transfer within the surge brake actuator, enabling the heater trailer to brake in proportion to the towing vehicle — critical during transport on public roads.
- Towing Safety Compliance — Surge brake systems on towable equipment must meet road-use requirements. Using the correct OEM brake line kit keeps the braking system operating within its designed parameters and supports compliance with trailer brake regulations.
The brake line in a surge brake system carries hydraulic fluid from the actuator at the trailer hitch to the wheel brake assemblies. When the towing vehicle decelerates, the surge actuator compresses and builds hydraulic pressure through these lines, applying the trailer brakes automatically and proportionally. A cracked, leaking, or degraded brake line bleeds pressure from the system, resulting in reduced or complete loss of braking force at the trailer wheels — a serious safety hazard when towing heavy indirect-fired heater equipment on public roads or jobsite access routes.
