The Wacker Neuson Left Hand Brake Complete is a genuine OEM braking assembly designed for G70 mobile generators, HI750GM and HI900DGM indirect air heaters, and MGT1S and MGT2SD mobile generator trailers. As a direct OEM replacement, this assembly is manufactured to Wacker Neuson's exact specifications, ensuring consistent brake engagement and correct fit right out of the box. This part covers an extensive range of trailer-mounted and mobile equipment configurations across both surge-brake and standard setups, including the MGT2SD dual-axle platform. Keeping your trailer braking system in proper working order is critical for safe towing and transport of heavy equipment on job sites and public roads.
Key Features
- Genuine OEM Braking Integrity — Manufactured by Wacker Neuson to the same engagement force and travel specifications as the original assembly, so stopping performance stays consistent across all supported configurations.
- Direct-Fit Assembly — Supplied as a complete left hand brake unit, meaning all sub-components arrive pre-assembled and aligned for straightforward installation without sourcing individual pieces.
- Broad Equipment Compatibility — Fits G70 mobile generators, HI750GM and HI900DGM indirect air heaters, and MGT1S and MGT2SD trailer platforms across multiple build configurations including surge and pintle hitch variants.
- Restored Braking Response — A worn or failed brake assembly compromises trailer deceleration control; replacing with a correctly spec'd unit restores the intended stopping response under load.
- Safety-Critical Compliance — Trailer brake components are subject to towing safety regulations; using a genuine OEM assembly supports compliance with brake performance requirements for road and site use.
The left hand brake complete is the fully assembled braking mechanism on the left side of a trailer axle, responsible for applying friction to slow and stop the trailer wheel when the tow vehicle decelerates. On surge-brake trailer systems like the MGT1S and MGT2SD, the brake assembly activates automatically in response to the inertia of the trailer pushing forward against the coupler — making the condition of each brake assembly directly linked to how predictably the trailer stops. When a brake assembly wears out or seizes, braking force becomes uneven across the axle, which can cause the trailer to pull to one side during stops or fail to stop within a safe distance.
