87708440 ( GENUINE ) BRAKE CYLINDER

The 87708440 Brake Cylinder is a CNH Original (Genuine) hydraulic brake component designed for the rear axle shaft brake system of Case backhoe loaders. This brake cylinder is responsible for converting hydraulic pressure into mechanical force to activate the internal axle brakes, ensuring reliable braking performance and machine safety during operation.

This component is used in the rear axle brake and differential assembly and is identified as Item No. 9 in the exploded parts diagram. Manufactured to strict CNH OEM standards, the brake cylinder features precision machining, high-quality sealing surfaces, and durable materials to withstand high hydraulic pressure, heat, and continuous braking loads in demanding construction environments.

Using a genuine CNH brake cylinder ensures correct brake response, reduced internal leakage, and long service life compared to non-genuine alternatives.
