Overview
The ZF 2095.229.001 BRAKE SHAFT is a critical component within the WG100, WG130, and WG131 transmission series, responsible for transmitting braking torque directly to the output shaft assembly. This OEM genuine part ensures precise engagement and disengagement of the parking brake mechanism, preventing unintended vehicle roll. The SKU 2095.229.001 is machined from high-strength alloy steel to withstand the cyclic loads of heavy-duty industrial applications. It sits at the rear of the transmission housing, interfacing with the differential assembly and the axle bevel gear set to maintain driveline integrity under load.
Symptoms of Failure
- Intermittent brake drag or incomplete release — A worn brake shaft can cause the parking brake to remain partially engaged, leading to overheating and reduced fuel efficiency. This often manifests as a persistent “brake dragging” sensation during operation.
- Oil seepage from the output shaft seal area — When the brake shaft surface becomes scored or pitted, it damages the shaft seal, allowing transmission fluid to leak past. Look for drips near the rear housing flange.
- Audible clicking or grinding during brake application — Excessive play in the shaft splines or bearing journals produces a metallic noise when the brake is applied, indicating imminent failure of the 0750117075 TAPER ROLLER BEARING that supports the shaft.
- Gradual loss of parking brake holding power — As the shaft wears, the brake cam profile degrades, reducing clamping force. The vehicle may roll on inclines even when the brake is fully engaged.

Compatibility
This brake shaft is engineered specifically for ZF WG-series transmissions. Verified compatible models include:
- WG100 — All variants (WG100, WG100/2, WG100/3)
- WG130 — Standard and high-torque versions
- WG131 — Including WG131/1 and WG131/2
- WG180 — Limited compatibility; verify shaft length before installation
- WG200 — Requires additional clearance check with the 2095309059 DIFF.HOUSING
When replacing the brake shaft, always inspect the mating 2095109015 DIFFERENTIAL and the 2095209037 DIFFERENTIAL for wear patterns that may indicate misalignment.
