Overview
The ZF 2093.329.007 BRAKE SHAFT is a critical component within the WG100, WG130, and WG131 transmission assemblies, responsible for transmitting braking torque from the output shaft to the differential housing. This OEM genuine part, identified by SKU 2093.329.007, interfaces directly with the 2093109029: DIFFERENTIAL to modulate wheel speed during deceleration. Precision-machined from hardened alloy steel, this brake shaft ensures consistent engagement and disengagement of the parking brake mechanism within the transmission’s rear housing section.
Symptoms of Failure
- Intermittent brake drag or uneven stopping: A worn brake shaft causes the parking brake to engage partially, leading to overheating and reduced fuel efficiency.
- Oil seepage around the output flange: Degraded shaft seals allow transmission fluid to escape, often visible as drips near the differential housing.
- Grinding noise during brake application: Excessive play in the shaft splines creates a metallic chatter when the brake is applied, indicating imminent failure.
- Complete loss of parking brake function: A fractured brake shaft prevents the pawl from locking, leaving the vehicle unable to hold position on inclines.

Compatibility
This brake shaft is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 variants when used in conjunction with the 2093209094: DIFFERENTIAL assembly. For proper installation, ensure the 0750117075: TAPER ROLLER BEARING is correctly seated to prevent axial play. The shaft also pairs with the 2093309078: DIFF.HOUSING for sealed operation in heavy-duty applications.

Frequently Asked Questions
Q: How do I know if the 2093.329.007 brake shaft needs replacement?
A: Look for visible spline wear, oil leaks near the output seal, or a parking brake that fails to hold. A professional inspection using a dial indicator can confirm shaft runout exceeding 0.05 mm.
Q: Can this brake shaft be used with the WG180 transmission?
A: Yes, but it requires the 2093209094: DIFFERENTIAL and proper shimming to match the housing depth. Always verify spline engagement before final assembly.
Q: What torque should I apply to the retaining nut?
A: Tighten the shaft nut to 180 Nm, then rotate the shaft 90 degrees further to ensure preload on the 0750117075: TAPER ROLLER BEARING.
