Overview
The ZF 2095.129.005 BRAKE SHAFT is a critical actuation component within the WG100, WG130, and WG131 powershift transmission series. This OEM genuine part directly controls the engagement and disengagement of the parking brake or service brake pack, translating mechanical input from the shift mechanism into precise clamping force. Positioned within the transmission’s rear housing, the brake shaft interfaces with the differential assembly to secure the driveline when stationary. The SKU 2095.129.005 is manufactured to ZF’s original tolerances, ensuring a direct fit and reliable braking performance under heavy industrial loads.
Symptoms of Failure
- Intermittent brake drag or incomplete release: A worn brake shaft can cause the brake pack to remain partially engaged, leading to overheating and reduced fuel efficiency. Operators often report a “brake not fully releasing” sensation during operation.
- Oil seepage from the brake shaft seal area: As the shaft surface wears or corrodes, it compromises the radial lip seal, resulting in transmission fluid leaks. This is frequently searched as “ZF transmission oil leak near brake shaft.”
- Excessive free play in the brake pedal or lever: Wear on the shaft splines or actuation arm creates a delayed braking response, often described as “spongy brake feel” or “brake pedal goes to floor.”
- Grinding or clicking noises during brake application: A damaged brake shaft can produce metallic sounds as it contacts the DIFF.HOUSING or internal components, indicating imminent failure.

Compatibility
This brake shaft is engineered for the ZF WG series of powershift transmissions, specifically the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 series when used in conjunction with the correct TAPER ROLLER BEARING (0750117075) for proper axial support. For differential-side integration, the shaft works with the DIFFERENTIAL (2095109020) and the DIFFERENTIAL (2095209037) assemblies. Always verify your transmission model number before ordering.
