Overview
The ZF 4143.151.006 MULTIDISK BRAKE is a critical friction component engineered for precise torque control within the HL 100 and HL 270 series transmissions. This OEM genuine part functions as a hydraulic braking element, engaging multiple steel and friction disks to halt output shaft rotation under load. Positioned within the clutch pack assembly, the 4143.151.006 ensures smooth deceleration during directional shifts and PTO operations. For complete assembly integrity, this multidisk brake works in conjunction with the 4143101014 HOUSING and the 4143301025 HOUSING, which provide structural support and fluid routing. The SKU 4143.151.006 is manufactured to ZF’s exacting tolerances, guaranteeing consistent clamping force and thermal stability in heavy-duty industrial applications.
Symptoms of Failure
When the ZF 4143.151.006 multidisk brake wears beyond service limits, operators will notice distinct performance degradation. Delayed engagement during gear shifts is a primary indicator, as worn friction material reduces hydraulic pressure buildup. Transmission overheating under light load often accompanies this failure, caused by excessive slippage generating abnormal heat. Another common symptom is intermittent loss of braking force on inclines, where the transmission fails to hold position. Finally, metallic debris in the oil filter signals advanced wear of the disk surfaces, requiring immediate replacement of the 4143.151.006 and inspection of the 0634313603 O-RING for contamination damage.

Compatibility
This genuine ZF multidisk brake is engineered for the HL 100 and HL 270 series transmissions, commonly found in forklifts, telehandlers, and industrial loaders. Based on its friction disk geometry and spline count, the 4143.151.006 is also compatible with the following ZF models: WG180, WG200, WG210, and WG250 series. For proper sealing during installation, always replace the 4475280018 SCREW PLUG and inspect the 0634313603 O-RING to prevent fluid bypass. Cross-reference your transmission serial number with ZF service literature to confirm exact fitment before ordering.
