Overview
The ZF 0501.218.753 BRAKE is a critical OEM genuine friction component engineered for heavy-duty stopping power within ZF powershift transmissions used in construction machinery. This part functions as a spring-applied, hydraulically-released parking or service brake, directly engaging the output shaft to secure the machine when stationary. The SKU 0501.218.753 is precision-machined to OEM tolerances, ensuring consistent clamping force and heat dissipation under extreme loads. It sits within the transmission’s rear housing, interfacing with the axle assembly to provide reliable braking torque for wheel loaders, graders, and dozers.
Symptoms of Failure
- Transmission brake slipping under load: When the ZF 0501.218.753 wears, the machine may creep forward or backward on inclines, even with the brake engaged. This is a common long-tail search query for operators experiencing “ZF transmission won’t hold on hill.”
- Oil contamination from brake debris: Worn friction material can shed particles into the transmission fluid, causing “dark, metallic-smelling transmission oil” and clogging filters.
- Delayed brake release or dragging: A failing brake may stick partially engaged, leading to “transmission overheating during travel” and reduced fuel efficiency.
- Audible grinding or squealing: Metal-on-metal contact from worn linings produces a high-pitched noise, often reported as “ZF brake noise when stopping.”

Compatibility
This brake is designed for ZF powershift transmissions commonly found in construction machinery. Based on its design and part numbering, it is compatible with the following transmission models: ZF WG180, ZF WG200, ZF WG210, and ZF 4WG-200. It is frequently used in applications such as the DIFFERENTIAL HOUSING assembly, where it works in tandem with the DIFFERENTIAL (part 2093109018) and the DIFFERENTIAL (part 2093209023) to manage torque distribution. The TAPER ROLLER BEARING (part 0750117075) supports the brake shaft, ensuring smooth rotation and minimal axial play.
