ZF 4699.109.041 BRAKE | OEM Genuine Part

Overview

The ZF 4699.109.041 BRAKE is a critical OEM genuine component designed to provide controlled deceleration and secure holding within ZF heavy-duty transmission assemblies. This part functions as a spring-applied, hydraulically released brake, ensuring that the driveline remains stationary when the machine is parked or during specific operational phases. It is commonly installed in the output section of the transmission, directly interfacing with the final drive to manage torque loads. The SKU 4699.109.041 is engineered to meet strict factory tolerances, making it a direct replacement for worn units in construction machinery. When paired with the 4699103026: OUTPUT assembly, this brake ensures reliable power interruption and safety compliance in demanding environments.

Symptoms of Failure

When the ZF 4699.109.041 brake begins to degrade, operators may notice several distinct performance issues. 1. Machine Creep on Inclines – If the brake fails to hold, the vehicle may slowly roll forward or backward on a slope, indicating internal friction material wear. 2. Delayed Engagement or Disengagement – A sluggish response when applying or releasing the brake often points to hydraulic leakage past the piston seals, which can be exacerbated by a failing 0634303980: O-RING. 3. Unusual Grinding or Squealing Noises – Metallic sounds during braking suggest that the brake plates have worn down to the backing material, requiring immediate replacement. 4. Transmission Fluid Contamination – Excessive brake dust or debris can migrate into the oil, causing discoloration and reduced lubrication efficiency across the 4699102082: INPUT shaft area.

Technical Specifications

Compatibility

This brake component is primarily designed for use in ZF’s WG series powershift transmissions, which are prevalent in construction machinery such as wheel loaders, telehandlers, and graders. The 4699.109.041 is directly compatible with the following transmission models: WG180, WG200, and WG211. It also fits select variants of the WG150 series when used in conjunction with the correct 4699101065: HOUSING adapter. For optimal performance, always verify the brake’s spline count and pilot diameter against your specific transmission’s output shaft. The 4699004017: GK25 gear kit is often replaced simultaneously to ensure even wear patterns across the driveline.
