Overview
The ZF 0501.337.136 BRAKE is a critical OEM genuine component designed to provide reliable stopping power and torque hold within ZF heavy-duty transmission assemblies. Positioned as a friction brake pack within the planetary gear set, this part ensures controlled deceleration and secure parking functions in construction machinery. The SKU 0501.337.136 is engineered to exact ZF tolerances, making it a direct replacement for worn units in high-stress environments such as wheel loaders, graders, and excavators. When installed alongside the 4699001195: GK10LD clutch pack, this brake assembly works in tandem to manage power flow and prevent unintended motion during operation.
Symptoms of Failure
- Delayed or incomplete braking response: If the machine takes longer to stop or fails to hold position on an incline, the brake discs may be glazed or worn beyond specification.
- Transmission overheating during low-speed operation: A dragging brake due to warped plates or degraded friction material generates excess heat, often accompanied by burnt oil smell.
- Intermittent gear slippage under load: When the brake fails to fully engage, power is lost to the drivetrain, causing the transmission to slip between gears, especially during directional shifts.
- Hydraulic fluid contamination with metallic debris: Worn brake linings shed particles into the oil, which can be detected during routine filter inspections or oil analysis.

Compatibility
This brake part is primarily used in ZF WG series transmissions commonly found in construction machinery. Estimated compatible models include WG180, WG200, and WG210 series, as well as certain ERGOPOWER variants. It is frequently paired with the 4699101108: HOUSING which encloses the brake pack, and the 4699102172: INPUT shaft assembly that drives the clutch. For output-side applications, the 4699103058: OUTPUT flange connects directly to the driveline. Always verify your transmission serial number before ordering.
