Overview
The ZF 0501.336.547 BRAKE is a critical OEM genuine component designed for the internal braking system within heavy-duty ZF transmissions. This part functions as a dynamic friction element, engaging to halt rotational motion in the driveline during specific operational cycles. Positioned within the clutch pack assembly, it directly interfaces with the 4699001205: GK10 gear set to manage torque load. The SKU 0501.336.547 is precision-machined to OEM tolerances, ensuring reliable stopping power in construction machinery applications where sudden deceleration is required.
Symptoms of Failure
- Delayed braking response in excavators: When the 0501.336.547 wears, operators notice a lag between pedal input and actual deceleration, often described as “brake fade” during heavy digging cycles.
- Transmission overheating under load: A failing brake disc generates excessive friction heat, causing the transmission fluid to exceed normal operating temperatures and triggering warning lights.
- Grinding noise during directional shifts: Worn friction material produces a metallic scraping sound when the brake engages, particularly when transitioning from forward to reverse in wheel loaders.
- Oil contamination from debris: Degraded brake particles circulate through the system, often clogging the 0637885612: BREATHER and reducing hydraulic efficiency.

Compatibility
This brake disc is engineered for ZF WG series transmissions commonly used in construction machinery. It is a direct fit for the WG180 and WG200 models, as well as the WG210 series found in telescopic handlers and crawler dozers. The part also integrates with the 4699101095: HOUSING assembly and works in conjunction with the 4699102083: INPUT shaft and 4699103067: OUTPUT flange to maintain driveline integrity. Always verify your transmission model code before installation.
