ZF 5838.300.365 BRAKE LINE | OEM Genuine Part

Overview

The ZF 5838.300.365 BRAKE LINE is a critical hydraulic conduit within the final drive assembly of heavy-duty construction machinery. This OEM genuine part channels pressurized brake fluid from the axle housing to the wheel-end brake calipers, ensuring consistent stopping power under extreme loads. As a direct-fit component, the SKU 5838.300.365 replaces worn or corroded lines to restore full braking authority. It integrates directly with the 5838022003: REAR AXLE and the 5838109001: DIFFERENTIAL assembly, forming a sealed circuit that prevents fluid loss and contamination.

Symptoms of Failure

• Visible hydraulic fluid seepage near axle housing: A cracked or fatigued brake line often produces slow drips at the connection points, leading to low reservoir levels.
• Spongy or unresponsive brake pedal feel: Air ingress through a compromised line reduces hydraulic pressure, causing delayed braking response in wheel loaders and graders.
• Uneven brake pad wear on one wheel: Restricted fluid flow from a kinked or blocked line forces the opposite brake to overcompensate, accelerating pad degradation.
• Dashboard warning light for brake pressure: Modern ZF transmissions trigger fault codes when line pressure drops below 80 bar, often traced to this specific part.

Technical Specifications

Compatibility

This brake line is engineered for ZF powershift transmissions commonly used in construction equipment. It fits the following models: WG180, WG200, WG210, and WG250 series. The part also interfaces with the 5838300128: DIFFERENTIAL HOUSING and requires the 0750117075: TAPER ROLLER BEARING for proper axle alignment during installation. Always verify your transmission serial number before ordering.
