ZF 4699.109.032 BRAKE | OEM Genuine Part

Overview

The ZF 4699.109.032 BRAKE is a critical OEM genuine component designed to deliver precise stopping power and load-holding capability within heavy-duty construction machinery transmissions. This part functions as a friction-based braking element, typically located within the clutch pack or output shaft assembly, ensuring controlled deceleration and stationary security under extreme torque loads. The SKU 4699.109.032 is engineered to meet ZF’s original tolerances, providing reliable engagement and disengagement cycles in demanding environments such as wheel loaders, graders, and excavators. When installed alongside the 4699101046: HOUSING and the 4699301109: HOUSING, this brake ensures optimal alignment and hydraulic pressure distribution within the transmission system.

Symptoms of Failure

• Gradual loss of holding power on inclines – When the brake wears, the machine may creep or roll on slopes, indicating insufficient friction material thickness.
• Delayed engagement or shuddering during braking – Worn plates cause intermittent contact, leading to vibration or hesitation when the brake is applied.
• Overheating and discoloration of transmission fluid – Excessive slippage generates heat, often resulting in burnt-smelling oil and reduced hydraulic efficiency.
• Unusual grinding or metallic noises from the transmission housing – Metal-to-metal contact from worn friction surfaces produces audible scraping, especially during low-speed maneuvers.

Technical Specifications

Compatibility

This brake component is primarily compatible with ZF WG180, WG200, and WG310 series transmissions commonly used in construction machinery. It also fits select models of the ZF 4WG-200 and 6WG-200 power shift transmissions. For proper installation, ensure the 4699301017: BEARING COVER and the 4699301085: COVER are inspected for wear, as these parts directly interface with the brake assembly to maintain axial clearance and prevent contamination.
