Key Features
- Genuine OEM Spring Specification — Each spring in this kit is manufactured to the original compression and material grade requirements, ensuring the Mico brake assembly operates as intended.
- Direct-Fit Replacement — Engineered to install in place of the original spring components without modification, restoring the brake assembly to its correct operating condition.
- Broad Z-45 Family Coverage — Fits multiple Z-45 articulating boom variants including the Z-45/22, Z-45/25, Z-45/25J IC Power, Z-45/25J DC, and Z-45/25J Bi-Energy models.
- Brake Assembly Integrity — Worn or fatigued springs in a Mico brake assembly can compromise braking performance. Replacing them with the correct OEM kit restores the assembly to its full, specified holding capacity.
- Critical Safety Component — The brake system on an articulating boom lift is fundamental to operator safety. Using the correct OEM spring kit ensures the brake performs to the design standard for which the machine was certified.
The Mico brake is a spring-applied, pressure-released brake used on the drive system of articulating boom lifts. The springs within the assembly provide the clamping force that holds the brake engaged when the machine is at rest or when drive pressure is not applied — meaning the springs are what keep the machine stationary on a grade or elevated surface. When the springs weaken, crack, or break from wear or fatigue, the brake may not hold with full force, creating a safety concern and reducing operator confidence. Replacing the spring kit with a genuine Genie OEM part restores the assembly to its original holding specification and is a straightforward service step in a Mico brake rebuild or inspection.
