ZF 0501.215.757 BRAKE

Overview

The ZF 0501.215.757 BRAKE is a critical OEM genuine component engineered for precise stopping control within heavy-duty construction machinery transmissions. This part functions as a friction-based braking element that engages directly within the planetary gear set to halt output shaft rotation under load. Specifically designed for ZF’s powershift transmission architecture, the 0501.215.757 brake assembly ensures reliable deceleration during loader, dozer, and excavator operations. The SKU 0501.215.757 is manufactured to exact OEM tolerances, guaranteeing seamless integration with the 4699101046: HOUSING and the 4699301109: HOUSING that enclose the clutch pack. Without this brake, the transmission cannot achieve positive neutral or controlled descent on steep grades.

Symptoms of Failure

• Delayed engagement or “brake drag” – When the 0501.215.757 wears, operators notice a hesitation before the machine stops, often accompanied by a grinding noise during directional shifts. This is a common long-tail search query for “ZF transmission brake drag symptoms.”
• Transmission overheating under light load – A failing brake that fails to fully release generates constant friction, raising oil temperature beyond normal operating range. Search terms like “ZF brake overheating construction machinery” target this issue.
• Intermittent loss of park brake hold – On inclines, the machine may creep forward or backward even with the brake engaged. This symptom is frequently searched as “ZF park brake not holding on slope.”
• Oil contamination with metallic debris – Worn brake friction material sheds particles into the hydraulic circuit, visible during oil changes. This triggers searches for “metal shavings in ZF transmission oil.”

Technical Specifications

Compatibility

This brake is designed for use in ZF WG series powershift transmissions commonly found in construction machinery. Based on its disc dimensions and spline configuration, the 0501.215.757 is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG250. It also fits select variants of the 4WG-200 and 6WG-250 series used in wheel loaders and telehandlers. Always verify the clutch pack stack height when replacing this brake alongside the 4699301017: BEARING COVER and the 4699301085: COVER to maintain proper piston travel.
