ZF 5838.124.004 DISC BRAKE | OEM Genuine Part

Overview

The ZF 5838.124.004 DISC BRAKE is a critical friction component engineered for heavy-duty construction machinery transmissions. This OEM genuine part functions as the primary braking interface within the final drive assembly, converting hydraulic pressure into mechanical stopping force to control wheel or track rotation under extreme loads. Specifically designed to integrate with the differential housing, the 5838.124.004 disc brake works in concert with the 5838109007: DIFFERENTIAL to ensure precise torque distribution during braking events. The SKU 5838.124.004 represents ZF’s latest metallurgical formulation for heat dissipation and wear resistance in off-road applications.

Symptoms of Failure

• Intermittent brake fade under heavy load: When the disc surface glazes or warps, operators notice reduced stopping power during downhill grading or excavating cycles, often accompanied by a burning odor.
• Metallic grinding or squealing during engagement: Worn friction material exposes the steel backing plate, producing high-pitched noise that intensifies with the 0750117075: TAPER ROLLER BEARING rotation.
• Hydraulic fluid contamination in the brake chamber: Failed piston seals allow transmission oil to bypass, causing spongy pedal feel and visible leakage around the axle housing.
• Uneven braking torque leading to vehicle pull: Asymmetric disc wear from a failing 2095209019: DIFFERENTIAL causes the machine to drift during straight-line stops.

Technical Specifications

Compatibility

This disc brake is a direct fit for ZF WG180, WG200, and WG250 series powershift transmissions commonly used in wheel loaders, dozers, and graders. It also applies to the ZF 4WG-200 and 6WG-250 variants found in articulated dump trucks. The 5838.124.004 interfaces with the 0631329086: SPRING PIN that secures the brake piston assembly. For optimal performance, always pair this disc with the corresponding thrust washers and clutch disks listed below.
