Overview
The ZF 5838.200.026 DISC BRAKE is a critical friction component engineered for high-stress construction machinery drivelines. This OEM genuine part functions as the primary stopping mechanism within the axle assembly, converting kinetic energy into thermal energy through controlled friction. Positioned directly on the output shaft of the transmission, it interfaces with the 5838022003: REAR AXLE to ensure precise deceleration under heavy loads. The SKU 5838.200.026 is manufactured to ZF’s exacting tolerances, guaranteeing consistent clamping force and heat dissipation in demanding environments such as wheel loaders and graders.
Symptoms of Failure
- Reduced braking force during heavy loads: Operators may notice increased stopping distances when the disc brake surface becomes glazed or worn beyond the service limit.
- Intermittent transmission shudder: A pulsating sensation through the driveline often indicates uneven wear or thermal cracking on the 5838.200.026 disc brake.
- Visible metallic debris in axle oil: Contamination from friction material breakdown signals imminent disc brake failure, requiring immediate replacement.
- High-pitched squealing under partial engagement: This noise typically points to worn friction pads or a warped disc surface, compromising the 5838109001: DIFFERENTIAL performance.

Compatibility
This disc brake is designed for ZF’s heavy-duty transmission series, specifically the WG180, WG200, and WG250 models commonly deployed in construction machinery. It directly mounts within the axle housing and works in concert with the 5838300128: DIFFERENTIAL HOUSING to maintain driveline integrity. The 5838.200.026 also pairs with the 0750117075: TAPER ROLLER BEARING to ensure smooth rotational support during braking cycles. For optimal performance, always replace the disc brake alongside the associated stub axles and thrust washers listed below.
