ZF 4699.109.076 BRAKE | OEM Genuine Part

Overview

The ZF 4699.109.076 BRAKE is a critical OEM genuine component engineered for the internal braking systems of heavy-duty construction machinery transmissions. This part functions as a friction-based stopping mechanism, directly engaging within the transmission housing to control output shaft rotation and hold the vehicle stationary under load. Specifically, the 4699.109.076 brake assembly integrates with the clutch pack and hydraulic actuation system to provide reliable parking and emergency braking force. The SKU 4699.109.076 is precision-machined to ZF’s exacting tolerances, ensuring seamless fitment and long service life in demanding off-highway applications.

Symptoms of Failure

When the ZF 4699.109.076 brake wears out, operators typically notice gradual loss of holding power on inclines, a common long-tail search query for construction equipment. Another frequent symptom is intermittent transmission creep when the parking brake is engaged, indicating degraded friction material. You may also observe metallic grinding noises during brake application, which suggests the brake disc has worn past its service limit. Finally, hydraulic fluid contamination with friction particles is a telltale sign that the brake lining is disintegrating, requiring immediate replacement of the 4699.109.076 unit.

Technical Specifications

Compatibility

This brake is designed for use in ZF’s WG series powershift transmissions commonly found in wheel loaders, graders, and telehandlers. It is a direct fit for the ZF WG180, ZF WG200, and ZF WG210 models. Additionally, it may be compatible with certain variants of the ZF 4WG-200 and ZF 6WG-250 series. Always verify your transmission model and serial number against the OEM parts catalog before ordering the 4699.109.076 brake.

During installation, this brake interfaces directly with the 4699101123 HOUSING, which encloses the brake pack and channels hydraulic fluid. The 4699301208 HOUSING provides additional structural support for the output shaft. A secure seal is maintained by the 4699301017 BEARING COVER, while the 4699301085 COVER protects the brake from external debris. These components must be inspected for wear whenever the brake is replaced.
