ZF 4699.109.054 BRAKE | OEM Genuine Part

Overview

The ZF 4699.109.054 BRAKE is a critical OEM genuine component designed to deliver precise stopping power and load-holding capability within ZF heavy-duty transmissions. This brake assembly engages directly with the planetary gear set to control output shaft rotation, ensuring safe operation in demanding construction machinery applications. The SKU 4699.109.054 is engineered to withstand high thermal loads and repetitive engagement cycles, making it essential for wheel loaders, graders, and excavators. When installed alongside the 4699001092: GK10 and 4699101094: HOUSING, this brake forms the core of the transmission’s parking and emergency braking system.

Symptoms of Failure

• Transmission brake slipping under load – When the 4699.109.054 wears, the transmission may fail to hold the machine stationary on inclines, causing dangerous rollback during operation.
• Oil leaks around the brake housing – Worn seals or friction plate degradation can lead to hydraulic fluid seepage, often visible near the 0501329881: HOUSING COVER interface.
• Delayed engagement or grinding noises – Reduced friction material thickness results in a soft pedal feel or metallic scraping sounds when applying the brake, indicating imminent failure.
• Overheating transmission fluid – Continuous brake drag from a sticking piston generates excessive heat, causing fluid breakdown and reduced transmission life.

Technical Specifications

Compatibility

This brake is engineered for ZF WG series transmissions commonly used in construction machinery. It is a direct fit for WG180, WG200, and WG210 models, as well as select Ergopower and Ecomix variants. The 4699.109.054 also integrates with the 4699103063: OUTPUT shaft assembly and the 4699001092: GK10 clutch pack. For complete rebuilds, verify compatibility with your transmission’s serial number against ZF technical bulletins.
