ZF 0501.222.459 BRAKE

Overview

The ZF 0501.222.459 BRAKE is a critical OEM genuine component designed to provide reliable stopping power within heavy-duty construction machinery transmissions. This part functions as a friction-based braking mechanism, typically mounted inside the transmission housing to control output shaft rotation and hold loads stationary. The SKU 0501.222.459 is engineered to withstand extreme torque loads and high thermal stress, ensuring consistent performance in demanding environments like wheel loaders and graders. When paired with a 2093109024: DIFFERENTIAL, this brake assembly ensures precise load management and safety during operation.

Symptoms of Failure

• Transmission brake slipping under load – If the brake fails to hold the machine stationary on inclines or during digging operations, the 0501.222.459 may have worn friction surfaces.
• Oil leaks around the brake housing – Damaged seals or piston wear can cause hydraulic fluid to escape, leading to reduced braking pressure and contamination.
• Delayed engagement or dragging brakes – A sticking piston or degraded return springs can cause the brake to engage slowly or remain partially applied, generating excessive heat.
• Unusual grinding or squealing noises – Metal-on-metal contact from worn linings indicates imminent failure and requires immediate replacement.

Technical Specifications

Compatibility

This OEM brake is primarily compatible with ZF WG series transmissions used in construction machinery. It is commonly found in the WG180, WG200, and WG250 models, where it serves as the parking or secondary brake. The part also integrates with the 0750117075: TAPER ROLLER BEARING for shaft support and the 2093209095: DIFFERENTIAL for torque distribution. For housing integrity, the 2093309071: DIFF.HOUSING is a direct companion component.
