Key Features
- Genuine OEM Seal Material — Each seal in this kit is manufactured to Genie's original material and compression specifications for the Ausco brake assembly, ensuring correct seating and long service life.
- Complete Kit Format — All seals needed to rebuild the Ausco brake unit are included in a single kit, so the job can be completed without sourcing individual components separately.
- Broad Genie Compatibility — Fits Genie S-series telescopic boom lifts, Z-series articulating boom lifts, and GS large-platform scissor lifts — confirm your specific model and serial number before installation.
- Restores Brake Integrity — Worn or damaged seals in a brake assembly can allow fluid bypass and reduce braking effectiveness. Replacing them with OEM-spec seals restores the assembly to correct operating condition.
- Critical Safety Component — The brake system is directly tied to machine control and safe operation on aerial lifts. Using genuine OEM seals helps ensure the Ausco brake performs as Genie engineered it, supporting safe use at height.
The Ausco brake is a wet-disc brake unit used on Genie aerial lifts to hold the machine securely during operation and travel. The seals within the assembly prevent fluid from bypassing the brake components and maintain the pressure needed for consistent, reliable braking. When seals wear, crack, or degrade, the brake can lose holding capacity — a condition that must be corrected before the machine is returned to service. Rebuilding the Ausco brake with this genuine OEM seal kit restores the assembly to its designed operating state and is the correct first step when a brake inspection reveals seal deterioration or fluid weeping.
