Overview
The ZF 0501.006.766 BRAKE is an OEM genuine friction component engineered for high-stress environments within heavy-duty construction machinery transmissions. This part functions as a primary holding brake or a clutch pack brake element, depending on the specific planetary gear set configuration. It is designed to manage torque interruption and rotational deceleration inside the transmission housing. The SKU 0501.006.766 is a direct replacement unit that meets ZF’s original tolerances for heat dissipation and friction coefficient. This brake assembly works in conjunction with the 4699101093: HOUSING to contain hydraulic pressure, and it seals against the 0634303936: O-RING to prevent fluid bypass during engagement cycles.
Symptoms of Failure
When the ZF 0501.006.766 BRAKE begins to degrade, operators often notice delayed engagement when shifting from neutral to drive in wheel loaders or dozers. A second common symptom is intermittent brake drag causing transmission overheating, which manifests as elevated oil temperature warnings on the dashboard. Third, you may detect chattering or vibration during low-speed maneuvering, indicating uneven friction material wear. Finally, loss of holding power on inclines is a critical failure sign—if the machine rolls backward when parked on a grade, inspect the brake assembly immediately. These failure modes are frequently linked to contamination entering through a compromised 4699301175: HOUSING or a misaligned 4699301041: COVER.

Compatibility
This brake component is primarily compatible with ZF’s WG series powershift transmissions, including the WG180, WG200, and WG210 models commonly found in construction machinery such as compactors, graders, and telehandlers. It also fits select variants of the ERGO-POWER series used in rough-terrain forklifts. Always verify the stack height against the 0630513203: SNAP RING groove depth during installation. For final drive applications, cross-reference with the 0750110302: SHAFT SEAL dimensions to ensure proper sealing at the output shaft.
